Smart Ski Experience
A battery-free, connected device to enable a new way of learning, practicing and using skis
The device, which is attached to the ski, includes a power sensor and a Bluetooth™ communication module. It is powered by a piezoelectric energy harvester device that captures energy from the vibrations and micro-deformations of the ski.
The piezoelectric generator is used as a power sensor to estimate the effort applied by the skier. An artificial intelligence merges and analyzes data retrieved from both the onboard system and the smartphone. The skier receives feedback about his or her overall technical skills and ski level, as evaluated by the Memento French Ski Teaching Method (École Nationale du Ski et de l'Alpinisme).
The system also collects data on the usage of the ski. It was developed as part of a strategic partnership between Rossignol and CEA.
This innovation is based on CEA's expertise in embedded artificial intelligence (edge-AI) and mechanical energy harvester. It gives rise to a low-cost, battery-free system that can be used for a variety of applications in which movement is used to harvest energy:
• snow sports: snowboarding, sledge, bobsleigh, aetc.
• water sports: sailing, rowing, kayaking, kitesurfing, windsurfing, etc.
• walking and running
• road and mountain biking
• fitness and weight training equipment
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
