| 摘要 | A sensing apparatus that includes a polylactic acid film having a first surface and an opposing second surface. The polylactic acid film is molecularly oriented and thermally treated so as to have a shear piezoelectric property. An electrode arrangement is provided adjacent at least one of the first and second surfaces of the polylactic acid film, and is configured to detect a relative position of an input on the polylactic acid film and detect a pressure of the input toward the polylactic acid film. | ||

| 主权项 | 1. A sensing apparatus comprising: a polylactic acid film having a first surface and an opposing second surface, the polylactic acid film being molecularly oriented and thermally treated so as to have a d14 piezoelectric property; and an electrode arrangement adjacent at least one of the first and second surfaces of the polylactic acid film, the electrode arrangement being configured to detect a relative position of an input on the polylactic acid film and detect a pressure of the input toward the polylactic acid film based on a voltage generated within the polylactic acid film by deformation of the polylactic acid film. | ||
