| Abstract | ||||
| As we progress further and further into the 21st century, the need for more sustainable sensors in the new internet of things (IoT) era has become clear. In this paper, a cheap and effective self-powered sensor was made using commercial polyamide (PA) and polytetrafluoroethylene (PTFE). The sensor is based on the sliding mode triboelectric nanogenerator (TENG) and it consists of a rotating dielectric made of PTFE and stationary dielectric-electrode pairs made from PA and aluminum. The sensor was found to be effective as a self-powered one, outputting a maximum voltage of 2.6 V at a 100 MΩ resistive load and a current of 0.0625 ηA at a 10 MΩ resistive load. The maximum power output was 0.145 ηW at a resistive load of 40 MΩ. Although the power output was low, the high voltage output confirmed its usability as a self-powered sensor. The TENG-based sensor was then calibrated and was found to have a voltage sensitivity of 0.3626 V / (ms-1) and a rotational speed sensitivity of 0.3083 rps / (ms-1). Having two wind-speed-dependent variables increase the reliability of the sensor. This sensor is promising as cheap alternative to the already present self-powered wind speed sensors. | ||||
