# TDK InvenSense

> TDK InvenSense designs the tiny MEMS sensors that let machines feel the physical world - motion, sound, pressure and ultrasound. Founded in San Jose in 2003 and acquired by Japan's TDK Corporation in 2017, it pioneered the integrated 6-axis IMU and ships motion, microphone and ultrasonic sensors into smartphones, wearables, drones, cars, robots and industrial systems. Its work pairs CMOS-MEMS hardware with proprietary fusion firmware and increasingly edge AI, turning raw physics into usable signals for billions of devices.

- **Founded:** 2003
- **Headquarters:** San Jose, California, United States
- **Founders:** Steve Nasiri (Founder, former President, CEO & Chairman)
- **Team size:** ~750 employees (InvenSense business group)
- **Products:** SmartMotion (IMUs), SmartSound (MEMS microphones), SmartSonic (Ultrasonic ToF), SmartIndustrial / SmartAutomotive, SmartPressure / SmartEnviro
- **Notable:** Invented the first integrated single-chip 6-axis MotionTracking IMU., Supplied motion sensors to Nintendo Wii, Oculus Rift DK1 and major smartphones., IPO on the NYSE in 2011 under ticker INVN with ~$800M market cap.

## Products & services
