Flexible Piezoelectric and Dielectric Materials for Energy Harvesting and Storage
This community develops flexible polymer and ceramic composites that convert mechanical motion into electricity and store electrical energy in compact capacitors, primarily for powering wearable sensors and electronic devices.
The work centers on polyvinylidene fluoride (PVDF) and barium titanate ceramics, often combined into nanocomposite films to enhance dielectric properties and breakdown strength. Key technologies include triboelectric and piezoelectric nanogenerators that harvest energy from vibration and human movement. Recent efforts focus on high-entropy ceramic designs for energy storage and lead-free relaxor materials. Applications range from self-powered strain and pressure sensors to wearable health monitors, with a strong emphasis on mechanical flexibility and high energy density.
Fluorine research accounts for the largest share of this community's output at 6.1%, followed by titanium at 2.1% and barium at 3.6%. Fluorine also contributes the highest number of papers within this group, with 11,522 entries.
The community comprises 34,849 papers, published most frequently in Nano Energy, Ceramics International, and Chemical Engineering Journal.
Recent work includes machine-learning-guided design of high-temperature polymer capacitors, flexible triboelectric nanogenerators for sleep pattern detection, and self-powered sensors for medical monitoring, all consistent with the established focus on flexible energy conversion and storage.
