Self-sustained autonomous wireless sensing based on a hybridized TENG and PEG vibration mechanism

Autonomous wireless sensor nodes (WSN) for information acquisition and status monitoring, play an important role in the boom area of internet things (IoT) industry 4.0. Self-sustained power supply is pursuit massive practical applications but yet to be developed. Here we propose a novel hybrid piezoelectric generator (PEG) triboelectric nanogenerator (TENG) form self-sustainable WSN. The PEG consisting hinged-hinged PZT bimorph two T shaped proof mass, has output 6.5 mW excited 25 Hz at 1.0 g. also shows broadband characteristics thanks impact TENG tunable frequency due axial force. 30 serial LEDs sine vibration 20 shock are lighted up with proposed double voltage rectifier circuit by PEG, which can serve as alarming signals drop monitoring. accelerometer good linearity sensitivity 15 V/g 0–1.5 g optimized gap 1.5 mm. After low design, Arduino nano RF transceiver sustainably powered send acceleration signal wirelessly Zigbee. A VR train monitoring demonstration been conducted showing great prospect WSN harsh environments. hybridized mechanism achieve self-sustained autonomous node (WSN). • Both impact-induced behavior force-induced achieved PEG. remote
