| Abstract: | Flexible resistive sensors have applications in modern devices that implement tactile sensors for pressure and force sensing. The e-Cone is a low-cost prototype device developed by the University of Twente to measure grip strength. The last version of this sensor has a high resolution of 64x128 sensor pixels. However, the sensor exhibits significant cross-talk, which adversely affects the readout of sensing pixels when multiple pixels are simultaneously pressed. To address this issue, we present an evaluation method that utilises spring mechanisms to study the behaviour of a single sensing pixel. Additionally, we propose a modification to the acquisition PCB circuit aimed at reducing the cross-talk. Finally, we introduce a machine learning approach to compensate for the cross-talk effect, thereby enabling reliable pressure pattern measurement. |
