Miniature sensor

Abstract

A strain sensing apparatus including a deformable substrate is presented. The deformable substrate is configured to detect a strain of the body that can be coupled to the deformable substrate. Sometimes, the deformable substrate is a flexible substrate having an upper surface and an opposite lower surface. The lower can be coupled to the body. There are sensing elements fabricated within the flexible substrate and proximate to the upper surface to detect properties of the body. The strain sensing apparatus is able to detect different strain modes, such as whether the strain is the result of bending of a body or a uniaxial elongation. Furthermore, the apparatus is small and less fragile than most conventional sensors, making it easy to use.
