Motion Analysis » Inertial motion capture » Wi-Fi IMU sensor: STT-IWS


The STT-IWS is a wireless (Wi-Fi) Inertial Measurement Unit (IMU) with unique features. It can operate at high acquisition rates, up to 400 Hz, with an outstanding performance and efficient power consumption. It also offers data logging capabilities as well, which will be extremely useful when performing motion analysis of athletes or subjects moving away from the wireless network.
