wireless power transfer for iot devices

1. Charging for IoT Devices IoT devices are typically battery-powered, and in some cases, they are designed to be discarded once the battery runs out. This is because the cost of replacing or recharging the batteries is not considered worthwhile. IoT devices are often used in a scattered manner, and if devices containing batteries with chemicals are left unattended, they can have a negative impact on the natural environment. If a WPT (Wireless Power Transfer) system can be developed, this problem can be fundamentally solved. Our laboratory aims to implement a WPT system using drones. While there has been much research on charging drones, there has been little consideration given to utilizing the mobility of drones for wireless power supply. If this can be achieved, it will lead to the realization of a power supply system that eliminates spatial constraints.
