Multistage sensing device
First Claim
1. A multistage sensing device comprising:
- a substrate;
a deformable unit having a first body disposed on said substrate, and a second body disposed on said first body and opposite to said substrate; and
a sensor unit including a first sensor element and a second sensor element that are disposed in said deformable unit, said first sensor element being disposed between said second sensor element and said substrate,wherein said second sensor element is operable to measure deformation of said second body when an external force is applied to said deformable unit, and said first sensor element is operable to measure deformation of said first body when said first body is deformed by the deformation of said second body, andwherein said first body is formed with a first space, and said second body is formed with a second space.

Abstract
A multistage sensing device includes a substrate, a deformable unit, and a sensor unit. The deformable unit has a first body disposed on the substrate, and a second body disposed on the first body and opposite to the substrate. The sensor unit includes a first sensor element and a second sensor element that are disposed in the deformable unit. The first sensor element is disposed between the second sensor element and the substrate. The second sensor element is operable to measure deformation of the second body when an external force is applied to the deformable unit. The first sensor element is operable to measure deformation of the first body when the first body is deformed by the deformation of the second body.
