Background:

Wearable electronics require advanced materials like stretchable electrets.
Current stretchable electrets face challenges in balancing softness, durability, and charge density.

Purpose of the Study:

To develop a novel all-polymer hybrid composite electret with enhanced stretchability and longevity.
To investigate the performance and sensing capabilities of the new electret material.

Main Methods:

Fabrication of the composite electret using a casting and thermal curing process.
Characterization of electret properties including surface potential, stretchability, durability, and charge retention.
Assembly and testing of a self-powered flexible sensor utilizing the electret for human activity monitoring.

Main Results:

The developed soft composite electrets demonstrated a stable surface potential (-0.38 kV) over 30 days.
Achieved excellent stretchability (450% strain) and durability (15,000 cycles) with low hysteresis.
Successfully demonstrated a self-powered flexible sensor for human activity monitoring, with pressure mode yielding significantly higher output signals than strain mode.

Conclusions:

The proposed all-polymer hybrid composite electret offers a promising solution for soft, stretchable, and long-lasting energy storage in wearable devices.
The material's performance validates its potential for developing advanced self-powered flexible sensors.
Further investigation into the distinct sensing mechanisms in pressure and strain modes is warranted.
