As wearables become more commonplace in our daily lives, the need for new power sources to power wearables via smartwatches and fitness tracking devices is driving research. innovative technologySome time ago we explored the possibilities of the human body. Renewable energyfocuses on the possibilities posed by substances such as sweat by harnessing kinetic energy or released heat. foldable and stretchable device It can be placed on the skin and can generate power through human sweat, one of the most common “biofuels”.
this innovative technology project is the result of the combined expertise of the bioelectrochemical team at the University of Grenoble Alpes and the knowledge of our American counterparts in nanomachines, biosensors and nanobioelectronics. The basic principle is the reduction of oxygen and the oxidation of lactic acid contained in sweat.Regarding the types of materials they used for their devices, this developer technology project We used a mesh of nanotubes, polymers and enzymes carrying a series of flexible connectors printed straight onto the surface. An anode is an enzyme that takes electrons from lactic acid and transfers them to a molecule that acts as a cathode.
they eventually created bio batterythe first goal of the technology project was to develop a lactate sensor that would allow real-time measurement of physical effort. This is due to the fact that, when exercising, sedentary people release much more lactic acid, the compound behind the muscle soreness experienced in these situations. It is due to
of new bio batteryHowever, it won’t replace nuclear power plants for the foreseeable future, as it only produces enough power to power a small LED diode. According to its creators, it can currently generate only 70 microwatts worth of power per square centimeter.Nevertheless, this battery It’s an easy-to-manufacture, low-cost technology that researchers hope to optimize in the future so it can power more demanding devices.
bacterial battery
The battery developed by the University of Grenoble Alpes is not the only example of technology exploiting the potential of perspiration. produce electricityTwo years ago, researchers at Binghamton University in New York unveiled another battery model based on a stretchy material that carries bacteria that can feed on your sweat and generate electricity. In this approach, materials are embedded into sportswear for power. IoT deviceDevelopers of this new technology are also exploring potential uses for the electric charges found in the millions of bacteria that live in the human body.
