1. A method of charging a wearable electronic device, comprising:
- receiving ultrasonic wave transmissions at an acoustic horn, the acoustic horn being electrically and mechanically coupled to the wearable electronic device;
generating a concentrated ultrasonic wave signal within the acoustic horn;
directing the concentrated ultrasonic wave signal to a piezoelectric transducer and an AC-DC converter located within the acoustic horn to convert the concentrated ultrasonic wave signal into a charging signal;
charging a battery coupled to the wearable electronic device via the charging signal while the wearable electronic device is being worn; and
powering the wearable electronic device with the charged battery.
