The proposed flexible sensor structure utilizes a special series of Bristol paper as the main fabrication material, which is coated with electric paint graphite paste and silver paste. The implemented sensor system uses a planar absolute encoder-like sensing topology to locate the impact and has a low-cost and quick manufacturing process. The size of the structure is 210 x 18.56 mm with a thickness of approximately 340 mu m. It has an electronic read-out consisting of three identical Wheatstone bridge circuits and instrumentation amplifiers for each bit. It can detect the external forces in the range of 0.6N to 12N with a spatial resolution of 2.4 cm and 0.55 cm in horizontal and vertical axes, respectively. The proposed sensor structure is tested in a series of experiments using a robotic setup consisted of a pantograph mechanism and a direct drive linear motor. The experiments illustrate the results with measurement sensitivity as small as 1N and proper fatigue resilience against repetitive loads.eninfo:eu-repo/semantics/closedAccessDisposable DevicePiezoresistive SensorForce SensorPosition SensorSoft RobotsElectronic-SkinTactileStrainArticle2-s2.0-8513273877110.1109/JSEN.2022.31824761400714Q11399922Q1WOS:000828762500026
