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.
Claims5
A combination sensor, comprising:
- a bio-signal sensor configured to detect a bio-signal;
- a stretchable strain sensor configured to detect a strain caused based on stretching of at least a portion of the stretchable strain sensor;
- and
- a light-emitting element configured to supply light to the bio-signal sensor and the stretchable strain sensor,
- wherein the bio-signal sensor includes a first photo-detective element configured to detect reflected light wherein light supplied from the light-emitting element is reflected by an object of a living body,
- wherein the stretchable strain sensor includes
- an optical structure disposed in a path of light irradiated from the light-emitting element, the optical structure configured to have optical properties that change in response to stretching of at least the portion of the stretchable strain sensor, and
- a second photo-detective element configured to detect light transmitted through the optical structure or reflected by the optical structure.
