Multi-element acoustic recharging system

This invention describes a system to wirelessly recharge medical devices implanted inside a patient's body. Specifically, it uses an external device that sends ultrasound waves through the skin to the implanted device. The implanted device, which includes an ultrasonic transducer, then converts these sound waves into electrical energy to replenish its internal battery.

Why it matters: Filed before modern advancements in ultrasonic transducer efficiency and precise acoustic beamforming. These improvements make the targeted delivery and conversion of acoustic energy for IMD recharging more practical now.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedUltrasonic transducers, power management, medical device integration.
