Machine learning-based design enables more efficient wireless power transfer
Wireless power transfer (WPT) systems transmit electrical energy from a power source to a load without physical connectors or wires, using electromagnetic fields. This idea goes as far back as the 1890s, when Nikola Tesla famously experimented with wireless energy transmission. Today, WPT systems are widely used to power smartphones, electric toothbrushes, and wireless sensors for the Internet of Things. A typical WPT system has a transmitter coil connected to a power source. This transmitter converts the supplied power into an electromagnetic field, which is received by a receiver coil that ...
