Abstract

We present the details necessary for building a scalable, flexible, and universal sensor performance evaluation platform with an impactor-inspired sample chamber and a virtual pin grid array for maintaining electrical connections. The system is designed to accommodate a wide range of sensors varying in physical dimensions, electrical connections, and transduction mechanisms. By integrating a switch matrix system with a commercial chip carrier, we have built a platform for rapidly screening sensors for promise in military, homeland security, and commercial applications without requiring custom circuits or packages for each sensor technology. Intuitive, graphical software is written and provided to control and monitor temperature, flow rate, and electrical connections. The system is capable of operating and interfacing with a variety of vapor delivery systems for chemical vapor detection measurements of emerging sensor technologies.
