Abstract:
Printed electronics technology is a promising way of fabricating low-cost electronics without the need for masking and etching. In recent years, additive printing techniques, such as inkjet and screen printing, have been adopted to fabricate low-cost and large-area electronics on flexible substrates. In this work, the design of a 3-axial normal and shear force sensor was developed, that consists of four miniaturized printed capacitors. The partially overlapping electrodes are arranged in a manner so that force sensitivity in orthogonal directions is achieved. The base unit of this sensor has been fabricated using inkjet-printing and characterized. The force response of this sensor was investigated in a force range from 0.1 N to 8 N, the normal-force sensitivity was determined to be Sz = 5.2 fF/N and the shear-force sensitivity was Sy = 13.1 fF/N. Due to its sensing range, this sensor could be applicable in tactile sensing systems.
