MEMS BASED “SONAR ON A SILICON CHIP” ULTRASONIC TIME OF FLIGHT SENSORS

MEMS-BASED “SONAR ON A SILICON CHIP” ULTRASONIC TIME-OF-FLIGHT SENSORS

Electronics News Updates / By

TDK Corporation’s announces the immediate worldwide availability of the Chirp CH-101 MEMS-based ultrasonic Time-of-Flight (ToF) sensor. This ToF sensor utilizes a tiny ultrasonic transducer chip to send out a pulse of ultrasound and then listen for echoes returning from targets in the sensor’s field-of-view. By calculating the ToF, the sensor can determine the location of […]

Sound is produced by the PiezoListen piezoelectric speaker over a broader frequency range and with a greater output in the low range than any existing piezoelectric speakers, claims TDK. The speaker has an operating frequency range of 400 to 20,000Hz and achieves a high sound pressure of 80dB, even at low voltages of 24V peak to peak, or below. The PiezoListen
