Flexible Piezoelectric and Triboelectric Materials for Wearable Sensing and Energy Harvesting
This community develops flexible, composite-based materials that convert mechanical motion into electrical signals or power, primarily for wearable sensors, human motion monitoring, and self-powered electronic devices.
The research centers on polymer composites, specifically polyvinylidene fluoride (PVDF) and its copolymers, combined with fillers like barium titanate, graphene oxide, and carbon nanotubes to enhance dielectric and piezoelectric properties. A significant portion of the work focuses on triboelectric nanogenerators and flexible piezoelectric films designed for pressure, strain, and touch sensing. Applications are heavily oriented toward wearable electronics, including e-skin, health monitoring bands, and self-powered sensors that harvest mechanical energy from human movement. The materials are engineered for high sensitivity, flexibility, and integration into soft, conformable substrates suitable for long-term skin contact or textile embedding.
The largest share of this community’s output is found in Fluorine research, accounting for 8.7% of all Fluorine research and comprising 8,440 papers within this group. Barium and Gallium are also prominent, with Barium contributing 3.1% of its research and Gallium 2.4%.
The community comprises 30,038 papers, with the highest publication volumes in Nano Energy, ACS Applied Materials & Interfaces, and Advanced Functional Materials.
Recent work continues to focus on advanced hydrogel electrodes for long-term ambulatory health monitoring, high-temperature polymer composite capacitors, and biodegradable, self-healing flexible sensors for human activity detection.
