Green energy harvesting; Fabrication of Single Jersey wearable TENGs

We have developed simple, lightweight, and easy to upscale Single Jersey Wearable Tribo- Electric Nano Generators (SJWTENG) by employing two different (different polarity) fabrics. In addition, they were also coated with magnetic nanoparticles to increase the electrical conductance of the samples. Compression and Vertical contact-separation modes were adopted for studying the performance of the developed samples. The maximum voltage reached was a time-varying signal of 7.68 volts peak to peak volts with an approximate frequency of 50.5 Hertz. The rectified signal was observed to be 5 volts which was enough to light up an LED with a threshold voltage of 1.7 volts DC as well as charge 3.7 volts, 3.6Ah Li-ion battery pack. The system can be used to power the battery-powered IOT (Internet of Things) devices, widely used in medical and body sensor network applications. The technology used was very simple and easy to implement. A good step towards harvesting energy by using body movement which seems been wasted. The possibility of using other materials can also be explored shortly to impart sustainability to save the environment further.
