120 W Underwater Capacitive Wireless Power Transfer Demonstrator
This demonstrator was developed to investigate capacitive wireless power transfer (CWPT) in underwater environments. The setup validates modelling techniques, evaluates transfer efficiency through water, and demonstrates wireless power delivery above 100 W using a four-plate capacitive coupler.
