The Fraunhofer Institute for Integrated Circuits IIS in Germany recently presented one of the applications of the FitnessSHIRT, the wearable sports monitor that the institute is looking to launch in 2014.

The FitnessSHIRT is fitted with sensors that track physical metrics such as breathing, pulse, and changes in heart rate. The data collected is transmitted to a memory card or computer for analysis and monitoring.

The research team paired it with a smartphone app and an exercise bike to manage the motor output based on the shirt wearer’s physiological data — allowing the bike to adjust the training levels based on how tired or energetic the user is.


The project, called MENTORbike, shows how the technology can be applied to larger performance-based systems. The MENTORbike system uses data from the user’s body, the bike, and the smartphone app to make adjustments in real-time. The FitnessSHIRT collects the physiological data which is transmitted to a handlebar-mounted smartphone. The smartphone app analyzes the data together with other data like speed and energy, and adjusts the motor output of the bike based on it analysis.

The system allows for seamless training adjustments, as opposed to the person analyzing his stats after exercising and planning for adjustments for the next session.

The system was demonstrated at the 2013 Medica Trade Fair held last month in Dusseldorf.
