Battery life is a major challenge for mobile electronic devices. In terms of technology, this means finding ways to reduce power consumption, select the most appropriate batteries, and integrate energy harvesting systems that harness the energy in the environment to power the device.
With in-depth knowledge of low-power electronics and substantial experience developing energy-management systems, CEA Tech addresses all of these issues. CEA Tech is also developing a range of energy solutions, from micro fuel cells and micro-batteries to thermoelectric, piezoelectric, and PV energy harvesting systems.
Leti, a CEA Tech institute, and STMicroelectronics have developed a circuit that can harvest the mechanical energy produced by sporadic impacts in vibratory environments and enable self-powered devices.
A new hybrid polymer electrolyte technology with the capacity to enhance battery safety was developed for Solvay. The company has begun presenting the new technology to battery manufacturers.
Compressed data acquisition collects and analyzes only the useful part of a signal—the part that contains the most relevant information. A system to test the compressed acquisition of radiofrequency signals was set up in lab conditions.
For the first time ever, scientists at Liten used XPS to observe changes in the chemical composition of lithium-ion batteries during operation. The purpose of the research was to gain a deeper understanding of battery degradation mechanisms.
What if it was possible to harvest energyfrom any type of movement, fast or slow,regular or irregular? Enerbee has answeredthe challenge with a new breed of innovativemicrogenerators.

How to collaborate with CEA Tech teams ?
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.
