AB  - Purpose– The purpose of this paper is to provide a thin tactile force sensor array based on conductive rubber and to offer descriptions of the sensor design, fabrication and test.Design/methodology/approach– The sensor array consists of a sandwich structure. Sensing elements are distributed discretely in the sensor. Each sensing element has two electrodes and a piece of conductive rubber with piezoresistive property. The electrodes, as well as the conductive trace for signal transmission, are printed on the substrate layer by the screen printing technique. A scanning circuit based on zero potential method and an experimental set‐up based on balance to characterize the sensor array are designed and implemented in the test of the sensor array.Findings– Experimental results verify the validity of the sensor array in measuring the vertical tactile force between the sensing elements and the object.Research limitations/implications– In this paper, all the sensors are tested without calibration procedures and the procedure of the dynamic test is implemented by manual operation.Practical implications– The sensor array could be applied to measure the plantar force for gait detection in clinical applications.Originality/value– The paper presents a tactile force sensor array with discrete sensing elements to essentially restrict the cross‐talk among sensing elements. This paper will provide many practical details that can help others in the field.
