Self-Powered
Sensing for Smart Agriculture by Electromagnetic–Triboelectric
Hybrid Generator
Posted on 2021-11-29 - 12:35
The
lack of efficient, low-cost, distributed energy collection
methods is a vital factor restricting the application of the Internet
of Things (IoT) in smart agriculture. This paper proposes a method
based on triboelectric nanogenerator and electromagnetic generator
to realize self-powered IoT nodes and self-powered sensors at the
same time. An energy harvesting and sensing device based on electromagnetic-triboelectric
hybrid generator (ES-ETHG) is designed. The peak power of ES-ETHG
is 32.4 mW, which can supply power to IoT nodes for a long time with
power management circuits. In addition, ES-ETHG can critically measure
wind speed and wind level within the range of 3–15 m/s, and
accurately detect wind direction within 2 s. Furthermore, the self-powered
distributed weather sensing system based on ES-ETHG is developed to
realize the remote collection of wind speed, wind direction, temperature,
and humidity. This work proposes a solution for developing self-powered
IoT and sensor in the field of smart agriculture.
