A deformable complementary moisture and tribo energy harvester

Abstract

A deformable complementary energy harvester combining moisture-induced and triboelectric energy in a single cell is developed, offering mechanical resilience, high energy output, rapid capacitor charging, and potential in emergency guidance systems.

3D dendritic hierarchically gradient nanoflowers in situ grown on conductive substrates for efficient hydrovoltaic power generation

“…Numerous studies have reported materials with significant output power densities and provided valuable models for theoretical research. 7,10,53 However, achieving a trade-off between the selectivity and the permeability remains a challenge. In this study, hierarchical structures that facilitate rapid ion flow while maintaining high selectivity were constructed.…”

Advancement of 2D Material-Based Moisture-Enabled Nanogenerators

“…The directional movement of protons has occurred due to the moisture gradient that works similarly to GO, MoS 2 , etc. Recently, a moisture and triboelectric nanogenerator has been developed by Kim et al 103 using 2D Ti 3 C 2 T x /melamine foam; one-fifth of the active sample has been coated with an organoionic hydrogel, which supplies water and ions to the uncoated MXene. A single unit of this highly deformable energy harvester generates electric energy by absorbing moisture and triboelectricity.…”

“…; a Ti 3 C 2 T x / melamine composite-based MEG generates power from moisture at 20−90% RH. 103 So, it is quite early to judge the best 2D materials for MEG Still, based on the few previously reported results, graphene QDs, GO/rGO composite, and GO fiber are the most efficient candidates for MEGs compared to other 2D materials. Hence, more exploration is still necessary to determine the best 2D materials for MEG applications.…”

“…For instance, a few works have been done using MXenes, such as Ti 3 C 2 T x , Nb 2 CT x , , etc. ; a Ti 3 C 2 T x /melamine composite-based MEG generates power from moisture at 20–90% RH . So, it is quite early to judge the best 2D materials for MEG applications.…”
