Single electrode mode triboelectric nanogenerator for recognition of animal sounds

This research presents an innovative and sustainable solution by designing triboelectric nanogenerators (TENGs) for energy harvesting. The fabrication process of TENGs includes PDMS and aluminum. The two single electrode mode TENG was designed one is plain PDMS/Al and the other is porous PDMS/Al TENG devices. The porous PDMS/Al TENG device generated a voltage and current of 7 V and 5 nA for 2 cm ´ 2 cm device area. Moreover, the TENG system was employed to successfully charge capacitors, and recognize various animal sounds. This study underscores the promising potential of harvesting energy from body movements and powering of devices, paving the way for eco-friendly solutions to energy generation.
