A pressure detection structure and a touch device. The pressure detection structure comprises a base plate (1) and a sensor (4). A strain concentrated area (11) and a non-strain concentrated area (12) are provided on the base plate (1). The sensor (4) is arranged near the strain concentrated area (11) or within the strain concentrated area (11). The thickness of the base plate (1) in the strain concentrated area (11) is smaller than that of the base plate (1) in the non-strain concentrated area (12). The strain concentrated area (11) reacts sensitively to pressure, the strain deformation is apparent, and a detectable electric signal is generated when pressure is applied on the surface of the base plate (1). The touch device comprises at least one pressure detection structure, the operation of the pressure detection structure is sensitive, the cost is easy to control, and the pressure detection structure is adapted to environments requiring high on a dust-free condition, security and the like and is widely applied. |
