Opening Keynote: Dr Michelle Kiang, CEO – Chirp | Topic: MEMS Ultrasonic Sensing Solutions for Everyday Products

While ultrasonic sensors are widely used in automotive, industrial, and robotics applications, they are rarely used in consumer electronics because conventional ultrasonic transducers are too big and too power hungry. Chirp Microsystems, a TDK Group Company, has introduced a line of tiny, MEMS-based, ultralow power, ultrasonic time-of-flight (ToF) sensors. Ultrasonic ToF sensors offer numerous advantages over other range and proximity sensors. They deliver the most accurate range measurement regardless of target size or color and are immune to ambient noise. Also, unlike optical ToF sensors, they work in any lighting condition, including direct sunlight. While ultrasonic sensors have been used successfully for many years in industrial and automotive applications, MEMS-based ultrasonic sensors are the first that are small and low-power enough for space-constrained consumer electronics applications. This presentation will describe the fundamentals of ultrasonic time-of-flight measurements and provide an overview of the operation and capabilities of Chirp’s ToF sensors. Example use-cases will be discussed, such as object detection and room navigation for drones and robots, room-occupancy, human-presence, and gesture sensing for smart-home products, and ultrasonic ToF-enabled 6-DOF controller tracking for VR/AR/MR.
