CSEM was instrumental in developing the wireless communication transmission protocols and the ultra-low-power hardware/software to ensure the new AMPWISE system consumed as little energy as possible,” notes Damien Piguet, Project Manager of Integrated and Wireless Systems at CSEM. “The communication system supports thousands of wireless sensors scattered throughout the aircraft in star topologies. Intelligent hubs then manage up to 300 wireless sensors each and control their operating cycle to minimize power consumption,” he adds.
The electronics developed by CSEM offer ultra-low-power wireless communication functions; they can measure the physical quantities required for the application and manage the system's activity and recovered energy to ensure continuous operation. CSEM also integrated robust communication elements at all levels: custom antennas optimized for metallic environments, secure and efficient communication protocols, node management, and self-healing.
The project was finalized in July 2021, and applications for the new sensing system could go well beyond its intended scope. Its potential extends to other transport vehicles, including trains and electric vehicles.
The consortium includes one industrial partner, SENIS (CH), a sensor manufacturer, and SERMA INGENIERIE (FR), an OEM for aeronautical equipment. It also includes Imperial College London (U.K.), a university with a significant track record in Energy Harvesting, including prototypes for aircraft, and CSEM, who coordinated the project thanks to its long experience in IOT, space and aeronautical projects.
