摘要
Magnetoelectric transducers (ME) wireless power transfer systems (WPTS) offer a way to power small biomedical implants. However, if the ME receiver becomes misaligned the wireless power delivered to the load can be dramatically reduced. A dynamic transmit coil using actuators and physically rotating or moving the transmit coil reduces the misalignment between the transmitter and the receiver. We model the expected power gains a WPTS has using a dynamic transmitter versus a static transmitter (a coil that does not move or rotate). We experimentally show that adding a single servo motor to make a dynamic transmit coil increases the power available to load by a factor of 2.4 over an otherwise identical static transmit coil for a given misaligned ME receiver in a WPTS.
