Indian Scientists Develop Flexible Nano-Gold Energy Film

Recently, scientists from the Institute of Nano Science and Technology (INST, Mohali) developed an ultrathin nano-gold embedded flexible film that converts small temperature changes into electricity for wearable, self-powered electronic devices and smart sensors.

Key Points

Material Used: Scientists used polyvinylidene fluoride (PVDF), a flexible polymer widely used in sensing and electronic technologies.
Nano-Gold Innovation: Tiny hexagonal gold nanoparticles were embedded into films thinner than 100 nanometres.
Pyroelectric Effect: The film generates electrical signals from minor temperature fluctuations through enhanced pyroelectric performance.
Improved Efficiency: Gold nanoparticles improved optical absorption and thermal-to-electrical energy conversion efficiency.
Temperature Range: The system worked effectively within an ambient temperature range of 294-301 Kelvin.
Potential Applications: The technology may support wearable electronics, smart photodetectors, healthcare devices, environmental monitoring, and low-grade heat harvesters.
