A Mutual Boosting Self‐Excitation Hybrid Cell for Harvesting High Entropy Energy at 32% Efficiency

Abstract

The contact-separation process of TENG and deformation of DEG were carried out by a line motor (WEINERMOTOR WMU-090-D) with sinusoidal motion. The voltage signals of the generators were measured by an electrostatic voltmeter (Trek 370), and the transferred charges and short-circuit currents were measured by an electrometer (Keithley 6514).

Controllable Manipulation of Large‐Volume Droplet on Non‐Slippery Surfaces Based on Triboelectric Contactless Charge Injection

“…As a unique HV power source, TENG has been widely applied to fields requiring high voltage such as electrospinning, [37,38] dielectric elastomer actuator, [39,40] air purification, [41,42] and droplet manipulation. [43,44] The existing TENG-based droplet manipulation strategies usually employed conventional alternating current triboelectric nanogenerators (AC-TENGs), typically working in the free-standing mode to actuate the system.…”

Polynary energy harvesting and multi-parameter sensing in the heatwave environment of industrial factory buildings by an integrated triboelectric–thermoelectric hybrid generator

“…1,2 Taking advantage of hybrid generators incorporating multiple electricity generation mechanisms to harvest polynary energy from a single energy input source can maximize energy utilization and conversion efficiency, which may be a promising solution for the power crisis and is conducive to the development of self-powered micro-systems based on the IoTs. [3][4][5][6] Among the large number of energy input sources that exist in ambient environment, sunlight, falling raindrop, and hot-wind Powering widely distributed micro/nano sensors in real time is the emerging energy dilemma that needs to be solved urgently in the era of the Internet of Things (IoTs). There are many existing energy sources containing polynary energy forms in the ambient environment.…”
