Abstract
A displacement meter including a photonic crystal color conversion film configured to change in color in accordance with a deformation thereof, and a mechanism connected to the photonic crystal color conversion film is disclosed. The displacement meter may not only measure a pressure in a severe environment such as an outdoor environment or an underwater environment, but also may easily and conveniently measure deformation of a construction, without using a separate power supply device or separate measurement equipment.
Claims12
A displacement meter comprising:
- a photonic crystal color conversion film configured to change in color in accordance with a deformation thereof;
- a plurality of mechanisms respectively provided at opposite ends of the photonic crystal color conversion film;
- and
- an attachment configured to attach the mechanisms to an object to be measured,
- wherein the photonic crystal color conversion film is configured to change in color while being linearly deformed in linkage with generation of a displacement of the object.
