Look inside the silk screen press and find a battery

On our video, you can see some of the key drivers for the imminent growth of the business of the thin and flexible SoftBattery®, linked intimately with the success of the Internet of Things.

Firstly, any Thing that is a part of the Internet of Things needs power. It is as simple as that. Any object that communicates with the Internet needs to have a power source. Some use a lot of power, some less. Enfucell products are designed to serve the latter. The devices powered by Enfucell batteries are typically wireless sensors, using power-thrifty electronics components. They are a part of the last ten meters of the Internet. Like in most networks, the last meters actually contain the bulk of the connected devices. This means that the business potential is considerable.

Secondly, thin and flexible batteries open up the world of new innovation to engineers, who are looking for solutions for wireless sensors that fit anywhere. Whatever the thin opening, or a surface of flat or curved shape, where something worthwhile should be measured and sent off, a smart label or sensor patch can be a part of the design. The solutions are not only practical, but they can also be made visually attractive, as can be seen on the video.

The wireless sensors are using two principal technologies for data read-out: Bluetooth and NFC. Bluetooth is a well-established technology since the early days of cellular phones. Originally used for connecting accessories like earphones or media players to phones, Bluetooth is finding a new boom in connecting a multitude of sensors to the Internet of Things. Bluetooth LE (Low Energy) is a recent variant of the original standard, having the benefit of a lower transmission power. This has made it possible to use the Enfucell SoftBattery® as power source for wireless sensors. The maximum output current of our battery is superior to any other thin and flexible battery in the market, allowing a simple electronics design for the sensor.

NFC data transmission is a smartphone-readable variant of RFID technology. For NFC applications, such as temperature loggers, Enfucell batteries can provide power for functions like sensor measurements and storing the data in a memory. The battery life of such devices can extend up to several months, even one year.

After read-out, you just monitor and analyse the data on a smartphone, tablet, or in the cloud.

Enfucell crowdfunding campaign was opened to public subscription on September 6, and will remain so until September 30. Please feel free to take a piece of our future success.

Cool applications with Enfucell SoftBattery® products - adjustable expiry dates, interactive movies

I have earlier written about some key applications where we see great potential for the use of thin and flexible power sources. The examples, based on Enfucell's work with partner companies, were for logistics, sports and healthcare. The logistics device that we have developed in a consortium with NXP is a smart label for cold chain monitoring. For sports, I described our Golf Sensor Patch, developed with Qualcomm and Nordic Semiconductor. My example for healthcare was the soft skin-attachable wireless sensor patch, which measures vital signs, and transmits them to care personnel.

There is no limit to what kind of wireless sensor patches can be designed, all thin and flexible. I am giving some food for thought in the examples below.

For logistics, I would like to see an application, where the temperature measurement performed by a smart label would be combined with an algorithm, which could adjust the "Use before" date of a dairy product or some other foodstuffs. There is at present a big public debate about the amount of food that goes wasted because it has passed its expiry date. If an intelligent label were used to indicate and adjust the expiry date, taking into account the real cold chain history experienced by the product, much of the foodstuff waste could be eliminated. This would bring major savings to world economy, not to mention the ecological effect of the reduced amount of household waste. With the help of new electrochromic displays, it is possible to change text with very little electricity.

In sports, we foresee that wireless sensors, equipped with accelerometers and gyroscopes, will find use in multiple disciplines. Combined with smart algorithms, the performance of an athlete in any racquet sports can be perfected by analysing the movement of the racquet, and indicating the exact trajectory in 3D. Tennis, badminton, and ice hockey are just some examples of good target sports for wireless sensors. The sensor can be a good substitute for a coach, who cannot be present all the time during the training sessions of an athlete. The performance can be viewed, and the key performance indicators studied together with the coach, when he/she is available.

For healthcare, we believe that there will be many specific clinical use cases for novel sensors, which will be able to measure a particular signal from the human body. As the signal is best observed at close proximity to the organ, which generates it, the freedom to choose the location of the sensor becomes very important. Using a soft skin-attachable sensor near the heart, lungs, muscles or blood vessels would make the measurement more accurate than measuring at a distance, say on the wrist of a person.

For the entertainment industry, it would be a great idea to measure the heart rate or some other vitals that react to the excitement level of a person, and use the wirelessly transmitted information in a feedback loop to change the contents of an interactive movie or a computer game. The healthcare sensor patch would be a good starting point for such a cool application.

Scalable business model for thin and flexible batteries - how does it work?

How does one do business on global basis, in a growing market, while maintaining a lean balance sheet? Enfucell thin and flexible SoftBattery® products are meeting the demand coming from the Internet of Things revolution without major investment in manufacturing facilities. How do we do this in practice?

The starting point is IPR. Enfucell currently holds several patents in key market areas in the EU, in USA and in China. Patents cover proprietary solutions in battery structure, materials and chemicals, production methods and electrical connections. All in all, Enfucell's core technology is already patented, approved and applicable to proprietary use in various battery and IoT-related uses. We sell licenses and technical support services to manufacturers willing to produce Enfucell batteries, and to sell them to their respective customers. We also provide them with proprietary materials needed for battery production.

We have a technology center at our headquarters in Vantaa, Finland. This is the place where the development of the basic battery technology has taken place over the years. We have a small but strong team of technology experts, who are designing new battery shapes and structures to meet the need for customized batteries in customer-specific applications. We also have a silk screen press, which we use for manufacturing small prototype series, and a quality assurance laboratory, where we qualify the inbound battery materials and the outgoing materials and batteries. For customized batteries, we typically have them qualified by the end customer, and then help our license manufacturers to fine-tune their production setup for the particular design.

We currently have seven licensees, who are able to manufacture Enfucell-designed batteries globally, or for specific markets or applications. The licensees are located on three continents: Europe, North America and Asia.

In addition to the battery licenses, Enfucell has revenue streams from customer driven device development projects and from the sales of low-cost IoT devices. We subcontract the manufacturing, and selected parts of the design of such devices. Enfucell is using device development projects as a means of extending its business from battery license and materials supplier towards being a developer and supplier of IoT devices.

Below, we illustrate the main elements of our business model, and the revenue streams.

Why does the Internet of Things need thin and flexible batteries?

On what grounds did I state in my previous blog that it is difficult to connect a milk carton, a golf club or a blood bag to the Internet? What is the common factor between such objects, as far as powering them up is concerned? How about human skin? Is the location of a wearable device for health monitoring limited by user comfort due to bulky batteries?

At Enfucell, we have studied different use cases of IoT devices, and come to the conclusion that there is a significant part of the Internet of Things that requires the device to be thin and flexible, and the same requirement goes for the battery as well.

In logistics, a typical use case is an intelligent label, capable of sensing conditions of the surroundings, such as temperature, humidity, pressure, impact or tampering. It is expected that such a label stores the information in a local memory, which can be read out at the receiving end of transport, to makes sure that the product is intact and safe to use. In most common packages an intelligent label needs to be very light, so that the weight of the shipment is not increased, and thin, so that it does not protrude from the surface of the package, and risk being ripped off in different handling phases.

Sports is an important sector where digitalization is a key trend, as athletes are eager to understand more about their performance, and be able to follow it up on a continuous basis. One of the key characteristics of sports equipment is weight. For instance, in racquet sports and in golf, the equipment has been optimized so that the physical effort needed to use it is at a minimum. Any additional weight due to a wireless sensor device sets off that fine balance, and distracts the athlete in his/her performance. A protruding element, due to a thick battery setup would also have an effect on the performance due to a change in air resistance.

Wearable devices need to be comfortable to the wearer. As conventional wireless health monitors or sports wearables contain a bulky metal-cased battery, they need to be worn in a place where they do not cause discomfort due to the thickness of the device. The perfect location for monitoring vital signs of a person is not on the wrist, but it is one of the places where people are used to wearing hard-shelled devices. Vital signs and performance indicators would be better sensed near the organs where they originate. The best wearable would be such that you can even sit or lie on it, and not feel any discomfort. A thin and flexible device would be the best solution - and that requires a thin and flexible power source.

With these three examples, I want to give you a sense of the benefits that can be reached by using thin and flexible SoftBattery® products, based on Enfucell technology. I believe that they also indicate that there is a genuine need for this technology, and a significant market opportunity within the Internet of Things that will help Enfucell to reach significant growth in the next few years.

Power to the Internet of Things now available to crowds

How would you connect a milk carton, a golf club or a blood bag to the Internet? Not an easy task, as it is difficult to find a power source for the electronics, which follows the contours of the object, and does not disturb its function.

Enfucell has been working on this for more than a decade now, and knows how to bring power to places that have been difficult to reach until now. The company has developed the know-how of manufacturing thin and flexible batteries, and has sold a manufacturing license already to six companies on three continents. The business model consists of selling technology licenses and special battery materials to manufacturers. This resembles the way that a successful global company like Coca Cola operates, keeping the capital requirements low, while maintaining a high level of scalability.

Enfucell battery technology has now been perfected, and is ready for large volumes, expected from a number of applications, starting later this year. The most important sectors to start utilizing Enfucell SoftBattery® technology in the nearest future are logistics, sports and healthcare. 

We are involved in each sector with partners, by developing customized prototypes of low-cost IoT devices using SoftBattery® technology. We will follow up selected projects by entering into the business of selling the devices.

Enfucell has an aggressive business plan, based on participation in the three key sectors, which is seems to be leading to a third year of revenue growth in a row. The business model will lead to high profitability, and makes us an attractive investment target. We are launching a crowdfunding campaign together with an established operator in the field, Invesdor. We aim to both expand and extend our reach within the growing IoT market through targeted use of the new funding. We are seeking EUR 800'000 in funding to make it happen rapidly. Funding will be used to ramp up sales and marketing efforts, and ensure quality controls and smooth production by licensees to meet growing demand.

Enfucell pursues funding through crowdfunding instead of venture capital funding, because we aim to broaden our investor base in preparation for a potential public listing. Assuming the successful implementation of plans, we are targeting a potential public listing, possibly on the First North marketplace during the next few years.

The funding campaign will be open to public subscription on September 6, and will remain so until September 30. Please feel free to take a piece of our future success.
