TDK Corporation’s (TSE:6762) 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 an object relative to a device and trigger a programmed behavior.
TDK’s MEMS ultrasonic technology leverages a proprietary ToF sensor in a 3.5 mm x 3.5 mm package that combines a MEMS ultrasonic transducer with a power-efficient digital signal processor (DSP) on a custom low-power mixed-signal CMOS ASIC. The sensor handles a variety of ultrasonic signal-processing functions, enabling customers flexible industrial design options for a broad range of use-case scenarios, including range-finding, presence/proximity sensing, object-detection/avoidance, and position-tracking.
CH-101 is the first commercially available MEMS-based ultrasonic ToF sensor intended for consumer electronics, AR/VR, robotics, drones, IoT, automotive, and industrial market segments. TDK’s MEMS ultrasonic product portfolio also includes the CH-201 ultrasonic ToF sensor for room-scale sensing applications, and Chirp SonicTrack™, a complete hardware-software system solution enabling inside-out 6-DoF controller tracking for AR/VR/MR systems.
