Flexible Nano-Gold Film for Self-Powered Electronics
In May 2026, scientists developed an ultrathin flexible film embedded with nano-gold particles that can convert small temperature changes into electrical signals.
Key Features of the Innovation
- Developed using:
- Polyvinylidene fluoride (PVDF) polymer.
- Hexagonal nano-gold particles.
- Film thickness Less than 100 nanometres.
- Converts thermal energy into electrical energy through Pyroelectric effect.
How does the Technology Work?
- Nano-gold particles improve:
- Electrical performance.
- Thermal-to-electrical energy conversion.
- Optical absorption.
- Gold nanoparticles help create: Highly ordered polar phase in PVDF film.
- Operates efficiently within: 294-301 Kelvin temperature range.
Potential Applications
- Wearable electronics.
- Self-powered sensors.
- Smart photo detectors.
- Healthcare monitoring devices.
- Environmental sensing systems.
- Low-grade heat energy harvesters.
