Core Viewpoint - Panasonic Holdings is developing a microwave power supply system aimed at charging devices wirelessly, with initial applications expected for sensors in robots and potential future applications for smartphones, drones, and electric vehicles (EVs) by 2028 [2][5]. Group 1: Technology Overview - The technology utilizes microwave waves, similar to those used in microwave ovens, to charge devices. The power received decreases with distance due to the dispersion of waves in space [4]. - To enhance charging efficiency, Panasonic employs a method that allows microwave waves from multiple antennas to interfere with each other, creating stronger signals at the device's location [4]. - The system can charge devices up to 10 meters away and can simultaneously charge multiple devices, making it suitable for use in populated areas due to the lower frequency of the waves [5]. Group 2: Initial Applications and Testing - The initial focus will be on sensors installed on factory robotic arms, which will be tested starting in March to monitor operational status continuously [5]. - Due to the lower efficiency of power transmission, the technology is expected to be primarily used for low-power devices like sensors in the short term. More efficient power transmission methods will be needed for charging larger devices like drones or EVs [5].
