A New Band for Wireless Self-charging System


The fastest emergence of wearable devices is encouraging numerous studies conducted for the development of charging systems of wearable devices. A team from the Korea Advanced Institute of Science and Technology (KAIST) has developed permanent and wireless self-charging systems for low-power devices near-infrared (NIR) band radiation to electrical energy.

The recently developed technology can be useful in the charging system of flexible and wearable devices. Colloidal-quantum-dots (CQDs) are promising materials for manufacturing semiconductors, particularly, CQDs based on the PbS have facile optical uncountable from visible in the infrared wavelength. Hence, the platform can be applied to numerous devices like lighting, photodetectors, and photovoltaics.

The studies on optoelectronic devices has increased its power conversion efficiency (PCE) to 12%. However, these wearable electronics are having problems in charging systems as users need to charge their devices.

This idea of applying CQD PV was of the team from the Graduate School of Energy, Environment, Water, and Sustainability and this study was led by led by Professor Jung-Yong Lee. This team installed a stable and efficient NIR energy transformation strategy.

The team replaced the existing battery from the commercialized wearable from the bracelet which helps in monitoring healthcare with the self-charging systems.

It has higher photostability and efficient than the existing batteries. The researchers confirmed that the system can be employed in the low power wearable devices. Numerous platforms are using solar radiation, but this new platform has more advantages as this platform allows conventional devices are comfortable for wearing in daily routine and charged easily with NIR energy transformation strategy.
