Preparation and characterization of functional rubber materials based on the iontronic pressure sensing mechanism

  • In order to make the silicone material not only as a dielectric or substrate material in the flexible sensor, effective methods were used to make it play a greater role in flexible sensing by having iontronic pressure sensing characteristics. By modifying polydimethylsiloxane (PDMS), organic electrolyte was added to PDMS and doped with silica to obtain iontronic pressure sensing characteristics, and the microscopic morphology of the material was observed. The mechanical and electrical properties of the material were investigated by comparing the organic electrolyte content and surface roughness. Finally, the ionic rubber consisting of PDMS, organic electrolyte, and silicon dioxide (the mass ratio is 2 ∶1 ∶0.3) possesses good mechanical property with the Young′s modulus of 1.1 MPa, and high sensitivity up to 1.46 nF/(kPa·cm2).
