Abstract

Inexpensive and flexible sensors are being designed as inkjet-printed circuits (iPCs) to solve a dynamic range of conditional issues in the biomedical, environmental, civil and industrial fields. The combination of print pattern, material choice and layering structure give iPCs a robust platform for developing products not attainable with printed circuit boards (PCBs). In this paper, a fully printed pressure sensing array was created as a multipurpose device useful for pressure mapping applications; specifically for monitoring and mapping the gait of physically compromised hospital patients. The printed array of gate-less field effect transistors utilizes aluminum-doped zinc oxide (ZnO) as the semiconducting layer due to its piezoelectric properties. Testing shows single nodes in the array detect various levels of pressure, while the entire array acts as a pressure gradient map, depending on the circuit containment method. This paper is concluded with a discussion of testing and research for future applications.
