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.

Abstract: A stretchable insulating film may include a first insulating layer having stretchability and a second insulating layer on the first layer and having non-stretchability. The first insulating layer may include an elastomer and the second insulating layer may include a cyclic siloxane polymer framework. An electronic device may include the stretchable insulating film. A method of manufacturing the stretchable insulating film may include forming the first insulating layer and forming the second insulating layer. The forming the first insulating layer may include coating a composition including the elastomer or depositing the elastomer. The forming the second insulating layer may include injecting a cyclic siloxane monomer and an initiator on the first insulating layer into a reactor equipped with a heat source and performing a polymerization reaction by low-temperature vapor deposition.
