Electrets TRIZ Cases
- Composite Oxide Electret for High-Temperature Surface Potential
Composite oxide electrets with a 3 eV+ band gap hold high surface potential up to 200°C, overcoming polymer thermal instability.
- Strained Dielectric Meta-Materials With In-Plane Superdomains
Strain-engineered ferroelectric thin films use dense in-plane superdomains to suppress depolarization hysteresis and raise tunable dielectric response.
