Ultrasonic signals are like audible sound waves, except the frequencies are much higher. Our ultrasonic transducers have piezoelectric crystals which resonate to a desired frequency and convert electric energy into acoustic energy and vice versa. The illustration shows how sound waves, transmitted...

The integration of sensor and electronics is important to reduce size, cost and power consumption for a measurement system. Sensors based on piezoelectric ceramic materials traditionally have a low degree of sensor and electronics integration. This paper describes the design of a highly integrated...

The ultrasonic electronic generator transforms AC line power to a 20KHz signal that drives a piezoelectric convertor/transducer. This electrical signal is converted by the transducer to a mechanical vibration due to the characteristics of the internal piezoelectric crystals. The vibration...

...variations in the form of sound is the most common sensor application, which is seen in piezoelectric microphones and piezoelectric pickups for electrically amplified guitars. Piezoelectric sensors in particular are used with high frequency sound in ultrasonic transducers for medical imaging and industrial...

...to measure the natural frequency produced during vortex shedding include: Piezoelectric crystals and ceramics - These materials produce an electrical charge in response to an applied mechanical stress. As vortices pass the sensor, they apply the stress needed for the piezoelectric material to produce...
