Plasticized PVC‐Gel Single Layer‐Based Stretchable Triboelectric Nanogenerator for Harvesting Mechanical Energy and Tactile Sensing

Abstract

Triboelectric nanogenerators have garnered significant attention as alternative power sources for wearable electronics owing to their simple structure, easy fabrication, low cost, and superior power output. In this study, a transparent, stretchable, and attachable triboelectric nanogenerator (TENG) is built with an advanced power output using plasticized polyvinyl chloride (PVC)‐gel. The PVC‐gel exhibit very high negative triboelectric properties and electrically insulating PVC became an electrically active material. It is found that a single layer of PVC‐gel can act as a dielectric and as a conducting layer. The PVC‐gel based single layer of triboelectric nanogenerator (S‐TENG) creates output signals of 24.7 V and 0.83 µA, i.e., a 20‐fold enhancement in the output power compared to pristine PVC‐based TENGs. In addition, the S‐TENG can stably generate output voltage and current under stretching condition (80%). The S‐TENG can be implemented as a tactile sensor that can sense position and pressure without combining multiple elements or electrode grid patterns. This study provides new applications of power sources and tactile sensors in wearable electronics.

Control of the Biodegradability of Piezoelectric Peptide Nanotubes Integrated with Hydrophobic Porphyrin

“…Moreover, mechanical energies produced via heartbeat, blood flow, and motion in joints are not utilized; therefore, power generation devices based on the piezoelectric effect that harvest mechanical energy from the human body have attracted considerable attention. 5,6 Piezoelectric nanogenerators (PENGs) based on ceramic piezoelectric materials such as PZT, 7,8 BTO, 9,10 and ZnO, 11,12 and polymer piezoelectric materials such as polyvinylidene fluoride (PVDF) 13,14 and P(VDF-TrFE) 15 have been applied extensively. However, conventional piezoelectric materials contain harmful elements such as lead or can cause side effects to the human body, and they must be surgically removed after performing their role in the body; therefore, they are unsuitable for use in implantable electronics.…”

“…71 Moreover, a stretchable TENG using the PVC-gel-based single layer is reported with an output voltage and current of 24.7 V and 0.83 μA, respectively. 72 Moreover, previously, we have also developed several types of the nanogenerator devices, however in the present case, the output performance obtained from the paddy straw derived GQDs reinforced-ZnO nanosheets is several order higher than previous reports. For instance, we have used the vanadium doping to achieve the ZnO nanosheet morphology, and the maximum output current density was limited to 1.0 μA/cm 2 from V-doped ZnO nanosheet based piezoelectric nanogenerator.…”
