Scalable and Composable Flex Leak Sensor Sheet

Abstract

A scalable and composable flex leak sensor sheet composed of individual sensor tiles arranged in a matrix pattern. Each sensor tile features multiple redundant connections, ensuring functionality even if some traces are damaged. The sensor sheet is bendable and foldable, allowing the sensor sheet to conform to various shapes and sizes. The sensor tiles employ electrical traces on a flexible Printed Circuit Board (PCB). The sensor sheet can be cut into various shapes and connected to form larger composite structures. The first set of traces is located on the top side of the flexible PCB, and the second set of traces is located on the back side. The sensor sheet detects the presence of liquid by changing electrical properties when in contact with the liquid. The sensor tiles can be cut on three sides while maintaining electrical connectivity and functionality through the redundant connections.
