Remote Performance Measurement and Monitoring: RPM2 Device Validation

Kelly A Brooks


The RPM2 device is a state-of-the-art wireless, remote monitoring, pressure sensing device that is used for sports performance enhancement. The device measures several variables of interest to athletes, trainers, and coaches who can use these variables to correct mechanics, promote correct form, and potentially prevent injury, and when injury occurs, possibly speed recovery. RPM2 can measure body weight, pressure distribution and range-of-motion of lower extremities using four pressure transducers and a 9 access sensor embedded in a shoe insert. The device offers 3D tracking capabilities, wireless communication, and a secured user interface through Android/IOS phone applications.


RPM² has developed technology that will serve to enhance human performance. Performance enhancement in athletics, specifically with runners, is the company’s primary mission. Running performance is improved through gait analysis feedback. Sensors, embedded in shoe inserts monitor the distribution of pressure on the soles of each foot.  A 9 access sensor is embedded in a microcontroller in each insert, creating a gyroscope. This effectively measures range of motion of the lower extremities.  Measurements of pressure distribution and range of motion provide evaluative data relating to gait and bilateral equivalency.
