Piezo Switches and Ultrasonic Sensors

Piezoelectric film (PVDF) ultrasound transmitter and receivers offer unique advantages for air ranging applications. Depending on the application, resonance frequency and vertical beam directivity of the transmitter and receiver can easily be...

Piezoelectric film (PVDF) ultrasound transducers offer unique advantages for air ranging applications. Cylindrical 80kHz PVDF transducers exhibit omni-directional horizontal beam directivity and broadband characteristics. These characteristics lend...

The NDT1-220K element offers outstanding ultrasonic transducer performance in a low-cost, flexible format for general-purpose use. 3 MHz nominal center frequency, with extremely low Q-factor of 1.3 (air-backed, into PMMA). Electrical impedance is...

Piezoelectric film (PVDF) ultrasonic transducer, wide angle GaAs IrLEDs, flexible printed circuit strip, and plastic tip guard assembly, for use in digitizer pen applications. The cylindrical transducer gives full 360° horizontal directivity and...

Piezo film's capabilities to generate a high voltage output under bending strain, combined with its rugged form factor, make it an ideal candidate for solid state impact switches. Rather than using a switch contact closure, the piezo film generates...
