Sweat as biofuel: scientists have developed a new source of energy for gadgets
Scientists in Tokyo have developed a device that allows sweat to be used as an energy source for sensors mounted on the skin.
Visually, the development is a paper bandage. Biofuel cells are lined with water-repellent paper, which must receive lactate - one of the constituents of sweat.
Depending on what voltage and power parameters are required by the sensors, the number of structural compartments is regulated. In each of them, through the interaction of lactate and enzymes, a current is produced. The latter moves to a common receiver of electric current.
This is not the first biofuel cell of its kind. Scientists have previously had to create something similar. But there are still design differences in the development. For example, using screen printing, which is cost effective in terms of mass production.
It is envisioned that the device will be used for miniature electronic sensors that help monitor performance of functional systems. The latter are so small that the problem of their energy supply is very acute - traditional batteries are bulky, and smaller devices for recharging create problems with energy consumption and safety.
The biofuel design of Tokyo experts will solve the problem of energy supply not only for miniature gadgets. Scientists plan to use their biocells for implants.
The test results were published in specialized journals, which allows experts from similar fields to familiarize themselves with them.
