wireless energy transfer

Wireless energy transfer is a way to send electrical power without physical cables, using electromagnetic fields or waves. It typically involves devices like coils or antennas that generate and receive these fields. When the transmitting device creates a magnetic or radio-frequency field, energy is transferred through space to a matching device nearby, which converts it back into electricity. This technology is used in applications such as charging smartphones, electric toothbrushes, or even powering sensors in remote locations, providing convenience and reducing dependency on cables while maintaining efficiency within certain distances.
