e-kayak
E-kayak is a data acquisition system for kayak and canoe.
E-kayak takes training and race analysis to the next level.
The system is composed of a control unit, up to 8 instrumented nodes (4 paddles and 4 footrests) and a software program for data visualisation and analysis.
The e-kayak system
The control unit contains a high frequency (20 Hz) GPS receiver with high gain external antenna, a triaxial accelerometer and a triaxial gyroscope. These sensors measure with high accuracy the distance, speed, acceleration and attitude (roll, pitch, yaw speed).
The great innovation of e-kayak are the instrumented paddles and footrests with wireless connection. They measure the force applied by the athlete with great accuracy, thanks to a conditioned full bridge of strain gauges, and send the data to the control unit at a frequency of 100 Hz.

The system has over 2 hours of autonomy, thanks to its LiPo battery and 8 GB onboard memory.
Acquired data can be downloaded via wifi and visualised on a powerful proprietary software tool.
