PRESSING-DETECTION DEVICE AND TOUCH PANEL |
摘要 |
The invention provides a pressure detecting device containing a pressurized member having a contact surface that is subjected to pressure due to contact with a pressurizing means; and a piezoelectric member that is arranged facing the pressurized member and that includes a polymeric piezoelectric material having a piezoelectric constant d 14 of 1 pm/V or more as measured by a displacement method at 25°C, and a ratio IEb/IEa between a product IEb of a cross-sectional secondary moment Ib and a Young's modulus Eb of the pressurized member, and a product IEa of a cross-sectional secondary moment Ia and a Young's modulus Ea of the piezoelectric member, is in a range of from 10 2 to 10 10 . |
