A way to make wearable technology more appealing to the average person. As most wearable converts use their devices for fitness, scientists have come up with a stretchable battery that can be inserted into clothes.
Like any battery, bio-batteries consist of an anode, cathode, separator and electrolyte with each component layered on top of another. Anodes and cathodes are the positive and negative areas on a battery that allow electrons to flow in and out. The anode is located at the top of the battery and the cathode is located at the bottom of the battery. Anodes allow current to flow in from outside the battery, whereas cathodes allow current to flow out from the battery.
Between the anode and the cathode lies the electrolyte which contains a separator. The main function of the separator is to keep the cathode and anode separated, to avoid electrical short circuits. This system as a whole allows for a flow of protons and electrons which ultimately generates electricity.
Although biobatteries are not ready for commercial sale, several research teams and engineers are working to further advance the development of these batteries. Sony has created a bio battery that gives an output power of 50 mW (milliwatts). This output is enough to power approximately one MP3 player. In the coming years, Sony plans to take bio batteries to market, starting with toys and devices that require a small amount of energy. Several other research facilities, such as Stanford and Northeastern, are also in the process of researching and experimenting with bio batteries as an alternative source of energy. Since there is glucose in human blood, some research facilities are also looking towards the medical benefits of bio-batteries and their possible functions in human bodies. Although this has yet to be further tested, research continues on the subject surrounding both the material/device and medical usage of bio-batteries.
