Summary
This case study details the collaboration between Infineon Technologies AG and Gore in the development of advanced photoacoustic spectroscopy (PAS) sensors for CO2 detection. The focus on improving indoor air quality has driven Infineon to enhance their gas sensor technology, seeking optimized performance and efficient manufacturing processes. The partnership with Gore was initiated to address the unique challenges presented by the compact design of the PAS sensors, specifically the need for a membrane that minimizes background noise while allowing gas diffusion. The engineering teams from both companies worked closely to develop a suitable solution, which included creating an acoustic test method to identify the appropriate membrane options. The results of this collaboration included a significant improvement in sensor response time, the simplification of the assembly process, and enhanced cost efficiency. This project not only strengthened the relationship between Gore and Infineon but also opened avenues for further applications of the new sensor design.
