Self-powered and self-sensing devices based on human motion

A supramolecular electrode with high self-healing efficiency at room temperature, recyclability and durability for dielectric elastomer generators

“…[1][2][3] In the eld of energy conversion, there is widespread interest in the dielectric elastomer transducer (DET), in which a thin dielectric elastomer (DE) lm is sandwiched between two exible electrodes, allowing the interconversion between mechanical energy and electrical energy under specic conditions, and therefore nding applications in articial muscles, micro-robots, sensors, energy harvesters, etc. [4][5][6][7][8][9] One of its most promising applications is the dielectric elastomer generator (DEG), [10][11][12][13] a kind of deformable elastic capacitor that can easily harvest electrical energy from natural mechanical energy such as human movements, waves, and tides with the help of stretching and energy storage devices. 14,15 Compared with traditional generators of large size and complex structures, the DEG has the advantages of light weight, high energy density and electromechanical conversion efficiency, exible structure, etc.…”

Mechanical Intelligent Energy Harvesting: From Methodology to Applications

“…Mechanical energy harvesting technology has been seen a boom in the last two decades. There have been published a number of excellent reviews that summarized from different perspectives, including, energy sources, [53][54][55][56][57][58][59] new materials, [60][61][62] electromechanical conversion mechanisms, [63][64][65][66][67][68] structure design, [69][70][71][72] circuit processing, [73] application scenarios, [74][75][76][77] etc. Adaptation to dispersed, uncertain, and irregular practical excitation is a critical issue in moving energy harvesting systems from the laboratory to practical applications.…”

Achieving High‐Performance Triboelectric Nanogenerator by DC Pump Strategy

“…[8,9] Among them, TENG, based on the coupling of triboelectrification and electrostatic induction, is considered as one of the most potential technologies to provide sustainable power supply for the widely distributed electronics due to the merits of low cost, light weight, simple formation, multifarious choice of materials and especially high efficiency at low frequency. [10] It has been demonstrated to gather the mechanical energy from the surroundings such as human motion, [11,12] wind, [13,14] water waves, [15,16] droplets, [17,18] etc., and shows enormous applications in self-powered sensors/ systems, [19,20] micro/nano-power sources, [21,22] blue energy, [23][24][25] and high-voltage power sources. [26,27] Nevertheless, enhancing its output performance is still highly desired, and also a challenge to promote the widespread applications of TENG.…”
