In an international collaboration, scientists have developed a kind of “bio-fuel cell” that can be worn directly on the body and supplied with energy by sweat alone. At the end of September 2019, French researchers from the Département de Chimie Moléculaire (DCM), a research unit comprising CNRS (National Center De La Recherche Scientifique) and the Université Grenoble Alpes, together with …
US colleagues from the UC (University of California) San Diego, presented a new flexible and stretchable construction that could, for example, supply portable electrical devices with electricity.
As reported in the journal Advanced Functional Materials, the first experiments involved laboratory experiments with carbon nanotubes and tiny biosensors. However, it is conceivable that in the future an energy supply using body fluids (e.g. lactate in sweat) could contribute to the permanent use of small electrical devices for medical purposes or for recording sporting activities. The researchers have already succeeded in ensuring that an LED lamp is permanently lit. Now they are working on increasing the resulting voltage, it was said.
