History of the Development of Ultrasound Technology

# The science of sound is an ever-evolving and vast study. It is documented as far back as the sixth century BC when Greek philosopher and mathematician Pythagoras constructed mathematical properties of stringed instruments. Sound waves, whether heard audibly or at such a high frequency that they cannot be heard by

Piezo Sensor Development from APC

Piezo sensors operate by converting a physical acceleration, pressure, or force to an electrical signal that will serve as an input to a data processing system. The signal from the sensor will often result in a response from the processing system. APC offers two piezoelectric materials for use in sensing applications:
