Natural ginkgo tree leaves as piezo-energy harvesters

Abstract

Ginkgo biloba has outlasted the dinosaurs, and is the oldest surviving tree on this planet. Here, we report for the first time the discovery of natural ginkgo tree leaves as...

Natural bioproducts’ hybridization creates transient dynamic electret nanogenerators

“…In the new era of Internet of Things (IoT), the rapid development of intelligent sports requires a maintenance-free, sustainable sensing technology for the real-time collection and real-time analysis of athletic big data. [49][50][51] As a proof of concept, in the practical scenario of pugilism training, the S-CNCsx piezo-device was used as a self-powered sensory system to monitor sports training activities in real time (Fig. 7).…”

Recent Advances in Self-Powered Tactile Sensing for Wearable Electronics

“…Generally, the sensitivity can be improved by reducing the intensity of the initial electrical signal. The commonly used methods include the introduction of microstructure [ 65 , 66 , 67 ], the use of new sensing materials [ 68 , 69 , 70 ], the introduction of small cracks [ 71 , 72 , 73 ], etc. The addition of bionic cracks has a number of benefits.…”
