Fig. 5: Measurement and analysis of ultralow crosstalk sensor arrays.

a Three-dimensional analysis of micro-cage structure formed by prslPDMS layer to isolate mechanical crosstalk, and the stressed pixels will affect the adjacent pixels from three directions (0°, 45°, 90°). b Displacement of PET and prslPDMS spacer model in different directions, and the model with spacer layer has almost no additional deformation to adjacent pixels. c Crosstalk simulations and corresponding voltage variation of sensors based on PET, PDMS and PDMS & prslPDMS layer, it could be found that the sensor arrays using the prslPDMS layer has less mechanical crosstalk and a clear pressure imaging. d A 6 × 6 sensor array used for pressure detection, and the imaging of the letter “B” could be seen clearly for the device with the prslPDMS layer. e Multichannel voltage variation of sensor array to detect the letter “B”. f Demo of application scenarios. The pixels of the sensor array are divided into four regions, which could be used to control the model movement in the game.
