STYLUS INPUT CAPACITIVE TOUCHPAD SENSOR |
摘要 |
A capacitive sensor comprises first and second sets of conductive traces and a compliant rugose material having a rugose surface located proximate to the first and second sets of conductive traces whereby deformation of the rugose surface causes a change in dielectric constant of the rugose material in the region of the conductive traces.
