Each neural dust mote possesses a piezoelectric crystal that can convert mechanical power from ultrasonic pulses broadcast from outside the body into electrical power. (businessinsider.com)
The researchers uncovered for the first time that the Pallas long - tongued bat use echolocation — a complex physical trait that involves the production, reception and auditory processing of ultrasonic pulses for detecting unseen obstacles or tracking down prey. (sciencedaily.com)
The piezoelectric crystals reflect some of the incoming ultrasonic pulses. (businessinsider.com)
