Evaluation of Post Thermo Formed Screen Printed Silver Electrode Capacitive Sensor

Abstract

The automobile industry is currently placing a premium on vehicle electronics and ergonomics in order to meet customer needs and future applications. Due to their fast production rate, flexibility, and complex geometries, flexible printed sensors (FPS) are now frequently suggested in the automotive industry. Flexible sensors with low manufacturing costs and strong formability for seamless cockpit integration may be easily made utilizing screen printing technology. Flexible printed sensors are hence perfect for IME-based infotainment bezels. The IVI bezel can be simply created in two-dimensional or three-dimensional shapes utilizing the IME method in accordance with the ECE21automotive standard. Capacitive sensors printed on a substrate provide a higher sensing performance and can be used in automobile bezels. The purpose of this effort was to design and optimize interdigitated pattern printed Ag electrode flexible sensors for enhanced vehicle infotainment applications. Flexible printed sensors exhibit superior sensing capabilities. With a 15mm overlap and a 0.5mm Electrode width, the capacitance change is greater and the production cost is lower. Because of the superior spatial interpolation, overlap has a stronger effect on sensor performance.
