Researchers in Bahia are working on new technology that allows energy to be generated during the walking process. New prototype could arrive in the coming months.
Researchers from Bahia are studying the possibility of producing and collecting energy from the walking process. In this scenario, the simple movement of the steps would turn into a renewable energy source and clean. Kinetic energy harvesting technology is being developed through a Federal University of the São Francisco Valley (Univasf), Juazeiro campus, guided by professor Helinando Pequeno de Oliveira.
Scientists from Bahia want to develop 'wearable devices' to collect energy from walking
The project in Bahia studies how to manufacture wearable electronics with the aim of developing parts that can collect energy from walking and transform it into electricity to charge electronic devices. Helinando highlights that the main objective of the research in Bahia is to produce a device that collects energy from body displacement.
The aim is for the triboelectric generator to capture energy from body movements and contact with clothing items, such as t-shirts, pants and sneakers. This energy will then be directed to power an energy storage device, such as a capacitor or supercapacitor, which, in turn, will provide the charge for electronic devices, making their operation independent of external recharging.

The team has been working with electronic wearables since 2018, with applications in energy storage, antibacterial activity and heat generation. According to one of the Researchers, the material needs to be comfortable, resistant, washable, resistant to washing machine traction and durable. The idea is that it is completely integrated into the garment.
É possible to cite as an example a prototype for use in the shoe insole. When the user steps on the floor, energy spikes are generated and stored in a device that makes all the energy saved available to charge a cell phone.
Device prototype cable to generate energy will be presented soon
The project, which is in partnership with the Universidade Estadual Paulista (Unesp), the Federal University of Pernambuco (UFPE) and the University of Araraquara (Uniara), is under development. Researchers from Bahia plan to present a prototype in the coming months.
According to the professor, the team is trying to come up with a patentable prototype of a wearable nano energy generator (TENG) soon.” In addition to Helinando, the team is made up of André Luiz, Iuri Custodio and Hermane Barud.
The State Secretariat for Science, Technology and Innovation (Secti) debuted on National Science and Scientific Researcher Day, July 8, 2019, a series of reports on how researchers and scientists from Bahia develop work in science, technology and innovation in order to contribute to improving the lives of the population in important topics such as health, safety, education, among others.
Other Advances in Generating Energy Through the Body
In addition to these advances in Bahia, the team of researchers from the University of Massachusetts Amherst, in the United States, developed a Biofilm that can take advantage of an energy source that has never been explored much: evaporation.
In short, researchers can generate clean energy with human sweat. The team of researchers developed a biofilm that transforms skin moisture into energy, generating continuous and stable renewable energy and can be used as an adhesive glued directly to the skin.
According to Xiaomeng Liu, a graduate student in electrical and computer engineering at the UMass Amherst College of Electrical Engineering and lead author of the article, this is a very exciting technology and is truly clean energy, different from other so-called energy sources. clean energy, its production is completely green.
