Ultralow Quiescent Power-Consumption Wake-Up Technology Based on the Bionic Triboelectric Nanogenerator.

ABSTRACT: Wake-up circuits in smart microsystems make huge contributions to energy conservation of electronic networks in unmanned areas, which still require higher pressure-triggering sensitivity and lower power consumption. In this work, a bionic triboelectric nanogenerator (bTENG) is developed to serve as a self-powered motion sensor in the wake-up circuit, which captures slight mechanical disturbances and overcomes the drawback of conventional self-powered motion sensors in the wake-up circuit that the circuit can only be triggered when a considerable pressure is applied on the sensor. The bTENG mimics the structure of plants and the addition of the leaf-shaped tentacle structures can increase the electrical outputs by four times, which largely extends the detection range of the wake-up circuit.
