Abstract
Provided is a sensor device in which the sensitivity of a strain sensor is hardly inhibited despite the fact that a glass material is used as a protective material, and in which the glass material hardly breaks. The sensor device of the present invention includes: an optical laminate including a glass film, an adhesive layer, a resin layer, and a pressure-sensitive adhesive layer in the stated order; and a strain-sensing unit, wherein the glass film has a thickness of from 20 μm to 150 μm. In one embodiment, the strain-sensing unit is arranged on a pressure-sensitive adhesive layer side of the optical laminate.
Claims5
A sensor device, comprising:
- an optical laminate including a glass film, an adhesive layer, a resin layer, and a pressure-sensitive adhesive layer in the stated order;
- and
- a strain-sensing unit,
- wherein the glass film has a thickness of from 20 μm to 150 μm;
- the resin layer and the pressure-sensitive adhesive layer are directly in contact with each other;
- a modulus of elasticity of the adhesive layer at 23° C. ranges from 0.5 GPa to 15 GPa;
- and
- the strain-sensing unit is configured to sense strain caused by an external force applied to a surface of the optical laminate.
