BAND WITH CONFORMABLE ELECTRONICS
First Claim
1. An electronic device, comprising:
- a band comprising a bistable structure, wherein the bistable structure has an extended conformation and a curved conformation, and wherein the band has a first surface;
a functional layer disposed over the first surface, the functional layer comprising;
at least one device island; and
at least one stretchable interconnect coupled to the at east one device island at a junction region;
one or more neutral mechanical surface adjusting layers disposed over at least a portion of the functional layer; and
one or more encapsulating layers disposed over the one or more neutral mechanical surface adjusting layers;
wherein the one or more neutral mechanical surface adjusting layers have a property that is spatially inhomogeneous relative to a location in the electronic device; and
wherein the at least one device island and at least one stretchable interconnect are disposed about the band such that the at least one 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.

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.
