Flexible alternating current electroluminescent devices integrated with high voltage triboelectric nanogenerators

Abstract

Flexible alternating current electroluminescence (ACEL) has attracted growing interest as promising wearable displays for its uniformity of light emission, low power consumption, and excellent reliability. However, the requirement of high-voltage...

Surface engineering of PDMS for improved triboelectrification

“…8 Modification of the polymer surface morphology can increase the generated charge. 9–14 An increase can also be achieved by optimising the architectures of the devices, 15–19 doing chemical functionalization of the surfaces, 20 or adjusting the electronic and physicochemical properties of the contacting polymer materials. 21–27…”

“…8 Modification of the polymer surface morphology can increase the generated charge. [9][10][11][12][13][14] An increase can also be achieved by optimising the architectures of the devices, [15][16][17][18][19] doing chemical functionalization of the surfaces, 20 or adjusting the electronic and physicochemical properties of the contacting polymer materials. [21][22][23][24][25][26][27] Chemical surface functionalization by self-assembled monolayers (SAMs) has been previously reported as an effective strategy for increasing the magnitude of triboelectric surface charge.…”

Highly Adaptive Liquid–Solid Triboelectric Nanogenerator-Assisted Self-Powered Water Wave Motion Sensor

“…The fundamental principle of the solid–liquid interfacing friction was discussed, which proved the effectiveness in the conversion of water wave energy. ,− The other mechanism is that, under the impact of water waves, the internal pressure of the device is in the horizontal direction. The latter process between the crumpled Ag layer and the PVC layer in the device is the classic contact–separation mode TENG. − As the water wave fades, the crumpled Ag layer is separated from the PVC with positive charge, while the PVC has an equal amount of negative charge. Therefore, as the separation distance increases, the electrons will flow through the external circuit to balance the potential difference.…”

Structural Flexibility in Triboelectric Nanogenerators: A Review on the Adaptive Design for Self-Powered Systems

“…However, the heavy power supply required to drive this kind of equipment has greatly hindered its commercialization process. Chen et al developed a self-powered flexible ACEL device with a TENG [ 77 ], which uses a simple and low-cost corrugated aluminum electrode. The resulting voltage and current can be as high as 490V and 71.74 μA., corresponding to a most extreme momentary result power of 1.503 mW/cm 2 .…”
