TDK: MEMS “Silicon Chip Sonar”

June 25, 2019

TDK Corporation will launch Chirp’s MEMS-based ultrasonic Time of Flight sensor (CH-101) worldwide.

Ultrasonic Time of Flight Sonar: (CH-101)

Transmit ultrasonic pulses using a small ultrasonic transducer tip.
Detects the echo returned from an object at the sensor’s viewing angle.
By calculating ToF, the sensor measures the location of the object relative to the device.
