A bicycle pedal which measures the cyclist’s power output

From 5th to 8th January 2017, CEA will be present at the Consumer Electronics Show (CES) in Las Vegas, with three radically innovative technologies: a general public headset for monitoring brainwaves, a smart and connected bicycle pedal and an obstacle detector for driverless cars.

Visitors to the Las Vegas CES, the number one meeting place for digital technology innovators, will be able to test three demonstrators of the most advanced technologies from CEA-Leti, at institute at CEA Tech (1).

 Push, the first innovative bicycle pedal 

Push is the first innovative bicycle pedal which measures power output, at one tenth the cost of existing systems, with a target price of under $100: this pedal is easy to use and can be adapted to all types of cycles (outdoor and stationary). It measures the force applied to the pedal and the pedalling cadence and then combines them to calculate and display the cyclist's power output in real time. A single Push pedal provides reliable power measurements and works whichever side of the pedal is being pressed. Amateur and professional cyclists can thus monitor their performance and improve their pedalling technique. This innovation makes power measurement accessible and paves the way for numerous applications (coaching, fitness, gaming)

  • What's new? The Push pedal sensors are coupled with data merging algorithms which enable the power output by the cyclist to be estimated to within 8%. The system incorporates wireless communication enabling the pedal to be connected to a smartphone. Its low energy consumption offers a range of more than 10,000 km without recharging.

Relax: a helmet to measure the state of relaxation

Relax is a headset offering the best compromise between ease of use and precision of brain activity measurement. It is very simple to install, which means that it can be used by anyone(*). Through the information provided by the headset and its smartphone or tablet application , the users of Relax can check their level of relaxation. In the future, the technology could also be adapted to control IT applications such as virtual reality, video games, or assistance systems for the disabled.

  • What's new? Relax is the first electroencephalography (EEG) brain activity measurement system working with dry electrodes (no contact gel). It aims to create a new standard for the development and dissemination of medical applications (it is compatible with medical certifications) as well for personal comfort and leisure uses.

 (*) Relax is based on a highly innovative technology, working without contact gel and can be used with precision by nearly all individuals (depending on hair mass and scalp thickness). It measures brainwaves but does not interact with the brain in return. It can be used at home or in the office and does not require a medical environment.

Sigma Fusion : Component embedded in autonomous vehicles

When installed on-board a driverless vehicle, Sigma Fusion is a digital component capable of interpreting the signals from a stereoscopic camera and two Lidars. It provides the car's automatic control system with precise and reliable real-time data on the position of obstacles and safety spaces around the car. It can also be fitted to drones or surveillance, rescue or security systems.

  • What's new? Sigma Fusion consumes less than 1 watt and is thus 100 times more efficient than equivalent systems currently available. It is compatible with a broad range of standard sensors. It is compact and inexpensive and can be used on production lines for all types of vehicles.
