Graphene foam is the future of IoT power, say Scottish boffins
By moving away from wearability and pocketable miniaturization, the team was able to create a floor sensor that could detect and draw enough electricity from a human step to power an Arduino computer. The sensor was also connected to software able to determine if someone was entering or leaving a room and who they were"based on measuring their unique temporal pressure profile," the team said in their paper.
3DG-TENG floor sensors could be used to manage energy usage in smart buildings by, for example, adjusting heating and cooling systems based on room occupancy, turning lights and other systems off and on when the first/last person enters/leaves, and the like. "We have proven that using … 3DG foam as an active layer in TENGs can work as a reliable and cost-effective energy harvesting power source for autonomous sensors and electronics," said Dr Carlos Garcia Nuñez, a lecturer in engineering and physical sciences at UWS and one of the authors on the research paper."This discovery has enormous potential for the booming global IoT industry.
