Claim 0:
1. 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.
