Internet of Things (IoT)
Self-Powered Weather Station
Bio-inspired technologies have remarkable potential for energy harvesting from clean and sustainable energy sources. Inspired by the hummingbird-wing structure, we propose a shape-adaptive, lightweight triboelectric nanogenerator (TENG) designed to exploit the unique flutter mechanics of the hummingbird for small-scale wind energy harvesting. The flutter is confined between two surfaces for contact electrification upon oscillation. With a six TENG network, the hybrid design attained a 1.5 W m-2 peak electrical output at 7.5 m/s wind speed. We demonstrate the ability of the H-TENG networks to operate Internet of Things (IoT) devices from sustainable and renewable energy sources.

Self-Powered Temperature Sensing Node
This work presents a fully enclosed duck-shape triboelectric nanogenerator (TENG) for effectively scavenging energy from random and low frequency water waves. The design of the TENG incorporates the freestanding rolling mode and the pitch motion of a duck-shape structure generated by incident waves. In addition, the hybrid system is experimentally tested to enable a commercial wireless temperature sensor node. In summary, the unique duck-shape TENG shows a simple, cost-effective, environmentally friendly, light-weight, and highly stable system.
