Abstract
A self-powered portable triboelectric nanogenerator (TENG) is used to collect biomechanical energy and monitor the human motion, which is the new development trend in portable devices. We have developed a self-powered portable triboelectric nanogenerator, which is used in human motion energy collection and monitoring mobile gait and stability capability. The materials involved are common PTFE and aluminum foil, acting as a frictional layer, which can output electrical signals based on the triboelectric effect. Moreover, 3D printing technology is used to build the optimized structure of the nanogenerator, which has significantly improved its performance. TENG is conveniently integrated with commercial sport shoes, monitoring the gait and stability of multiple human motions, being strategically placed at the immediate point of motion during the respective process. The presented equipment uses a low-frequency stabilized voltage output system to provide power for the wearable miniature electronic device, while stabilizing the voltage output, in order to effectively prevent voltage overload. The interdisciplinary research has provided more application prospects for nanogenerators regarding self-powered module device integration.
Highlights
With the development of technologies, the electric consumption of one electronic equipment becomes lower; the monitoring system integrated with lots of sensors still requires large power supplies [45,46]
The biggest issue in sport monitoring is that a battery with a short lifespan can lead to high-cost maintenance and environmental pollution
We find that triboelectric nanogenerator (TENG) can collect mechanical energy and convert it into electronic energy to charge the mini capacitor to drive micro electronic equipment in the test process
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Energy is a kind of physical resource that enables humanity in so many ways. With the increase of consumable devices and their functions in daily life, more energy is required to satisfy the respective demands [1,2,3,4]. Considering that humanity is fully aware of the consequences of non-renewable energy exhaustion for the planet, we should use renewable energy sources as much as possible in order to satisfy these increasing demands [5]
