Abstract: A conformal electronic device with a deformation indicator is disclosed. The conformal electronic device includes electronics operable to measure one or more parameters of an object on which the conformal device is disposed on or proximate to, a conformal layer that encapsulates the electronics, and a deformation indicator configured to indicate a deformation threshold of the electronics, the conformal layer, the conformal device, or a combination thereof.

Abstract: An electronic device is disclosed that includes a band, a functional layer disposed over the band, neutral mechanical surface adjusting layers disposed over a portion of the functional layer, and encapsulating layers disposed over the neutral mechanical surface adjusting layers. The band includes a bistable structure having an extended conformation and a curved conformation. The functional layer includes a device island and a stretchable interconnect coupled to the device island at a junction region. At least one of the neutral mechanical surface adjusting layers can have a property that is spatially inhomogeneous relative to a location in the electronic device. The device island and stretchable interconnect are disposed about the band such that the device island and the junction region are disposed at areas of minimal strain of the electronic device in the curved conformation of the bistable structure.
