WebAug 1, 2024 · An ultrasonic sensor is a system that can emit and receive ultrasonic waves. It is generally used to sense the distance to and from an object. It also belongs to the family of “transducers” because it generates ultrasonic waves from an alternating voltage. Thus, it transforms electrical energy into acoustic energy. WebUltrasound Wave Generation: Transducers, Frequency, Attenuation Medical ultrasound systems operate by exciting an array of piezoelectric crystals, causing them to vibrate at an intrinsic resonant frequency. Energy from the vibrating crystals is transmitted into the body in periodic waves of the same frequency. WebAbstract.
