Abstract
A stretchable strain sensor includes a light-emitting element, an optical structure, and a photo-detective element. The stretchable strain sensor is located in a path of light emitted from the light-emitting element. The optical structure is configured to have optical properties that change in response to stretching of at least a portion of the stretchable strain sensor. The photo-detective element is configured to detect light transmitted through the optical structure or reflected through the optical structure.
Claims20
A stretchable strain sensor, comprising
- a light-emitting element;
- an optical structure located in a path of light emitted from the light-emitting element, the optical structure configured to have optical properties that change in response to stretching of at least a portion of the stretchable strain sensor;
- a photo-detective element configured to detect light transmitted through the optical structure or reflected by the optical structure;
- and
- a stretchable light-transmitting layer that supports the light-emitting element, wherein each of the optical structure and the photo-detective element is supported by the stretchable light-transmitting layer, is coupled to the stretchable light-transmitting layer, or is embedded in the stretchable light-transmitting layer, wherein at least one of transmittance or reflectance of the optical structure changes in response to stretching of the stretchable light-transmitting layer.
