Chirp Microsystems, a startup enabled with technology developed at UC Davis and UC Berkeley, announced it has been acquired by Japanese electronics giant TDK Corporation.
Based in Berkeley, Chirp Microsystems makes tiny, ultra-low power sensors that function like sonar or echolocation, sending out ultrasonic sound waves and then measuring how long it takes for the returning echo to come back. The micro-electromechanical systems (MEMS) technology enables extremely precise sensing, ranging from several centimeters to several meters.
Chirp’s sensor technology can be used in drones, robots, vehicles, smart home products, augmented reality and virtual reality systems, and many other applications. Because the transducers are just a few millimeters across, they use very little power compared to a conventional ultrasound transducer.
Chirp was one of 13 companies enabled by UC Davis research during fiscal year 2014–15. The company licensed intellectual property from the University of California and currently owns over 20 patents covering the core MEMS device technology, application specific Integrated Circuits (ASIC) design, packaging, signal processing, ultrasound systems, and applications.
David Horsley, a professor in the UC Davis Department of Mechanical and Aerospace Engineering, is a co-founder of Chirp and the chief technology officer.
“Professor Horsley is an exemplar of the type of faculty entrepreneur who is driving societal impact through innovation in the collaborative environment that the University of California fosters, and that the UC Davis College of Engineering enables,” said Dushyant Pathak, associate vice chancellor of research and executive director of Venture Catalyst. “The novel sensor system that he invented and that was developed by Chirp Microsystems, where he was co-founder and chief technology officer, is an example of the cutting-edge technology and engineering innovation being driven by our faculty.”

Horsley and his graduate students developed the sensor technology collaboratively with Bernhard Boser, a professor in the UC Berkeley Department of Electrical Engineering and Computer Sciences. Much of the work was done at the Berkeley Sensor and Actuator Center, which conducts industry-relevant, interdisciplinary research on micro- and nano-scale sensors.
“UC research projects like ours fill an important role of conducting fundamental research that can have commercial impact,” Horsley said. “After the fundamental work was done, we founded Chirp based on a vision of tiny ultrasonic sensors in everyday devices, from smart-phones to robots. As part of TDK, Chirp will have the resources and global scale to make this vision a reality.”
The acquisition announcement from TDK highlighted Chirp’s synergies with TDK sensors and sensor fusion software libraries. TDK also noted the uniqueness of Chirp’s sensors: “Chirp’s ultrasonic sensors are robust, accurate, draw less power and are smaller than the ultrasonic range finders used in today’’s automotive applications and industrial solutions,” the company said in their statement.
Chirp will become a fourth business unit, Ultrasonic Tracking and RangeFinding, within InvenSense, a TDK Group company headquartered in San Jose. InvenSense is a world leading provider of MEMS sensor platforms. Chirp will remain based in Berkeley.
About Chirp Microsystems
Chirp Microsystems mission is to bring ultrasonic sensing to everyday products. Founded in 2013 based on pioneering research performed at the University of California, Chirp’s piezoelectric MEMS ultrasonic transducers offer long range and low power sensing capabilities in a micro-scale package, enabling products to accurately perceive absolute position in the three-dimensional world in which we live. Combined with Chirp’s embedded software library, these sensors advance user experiences with VR/AR, mobile, wearables, robotics, drones and occupancy detection.
