Abstract:
1. A pressure sensing device comprising: a first conversion layer and a second conversion layer that are made with elastomer having Young's Modulus of 0.1 MPa to 1.0 GPa; an electrically conductive element between the first and second conversion layers; and a pair of electrically conductive yarns, attached to a surface of the electrically conductive element, adapted to detect resistivity change of the electrically conductive element in between the pair of electrically conductive yarns, wherein the first and second conversion layers include at least one deformation member adapted to deform the electrically conductive element and change the resistivity of the electrically conductive element, when pressure exerts on the first and/or the second conversion layer.
