Problems solved by technology

However, this study used relatively thin metal film layers (e.g., about 105 nm) and was relatively limited because the system could potentially be made into an electrical conductor that could be stretched by about 10%

Embodiment 1

[0213] Example 1: A pullable with self-similar serpentine interconnection and integrated wireless recharging system Stretched battery

[0214] An important trend in electronics involves the development of materials, mechanical designs and manufacturing strategies to enable the use of unconventional substrates, such as polymer films, metal foils, paper sheets or rubber slabs. The last possibility is particularly challenging because the system must accommodate not only bending but also stretching, sometimes to high strain levels (>100%). Although several approaches are available for electronic devices, continuing difficulties exist in energy storage devices and power supplies with similar mechanical properties in order to allow co-integration of energy storage devices and power supplies with electronic devices. In this example, we provide a set of materials and design concepts for rechargeable lithium-ion battery technology utilizing thin, low modulus, silicone elastomers as...

Embodiment 2

[0298] Example 2: Device geometries and material strategies for stretchable electronic systems.

[0299] Figure 25 and Figure 27 An example fabrication process flow diagram for fabricating some electronic systems of the present invention is provided. Figure 25 Provide an overall manufacturing flow chart. Figure 26 Illustrates the silver glue scratch used to make the electrical contact between the serpentine interconnect and the COTS chip. Figure 27 Exemplary liquid chamber fabrication. A cavity or pocket is formed by laminating a thin sheet of elastomeric sheet on top of the substrate, and sealing at the surrounding perimeter is achieved under heat and pressure with uncured elastomer as glue. Fluid is injected into the formed cavity by injecting with a syringe through the side edge of the cavity.

Abstract

The present invention provides electronic systems, including device arrays, comprising functional device(s) and / or device component(s) at least partially enclosed via one or more containment chambers, such that the device(s) and / or device component(s) are at least partially, and optionally entirely, immersed in a containment fluid. Useful containment fluids for use in containment chambers of electronic devices of the invention include lubricants, electrolytes and / or electronically resistive fluids. In some embodiments, for example, electronic systems of the invention comprise one or more electronic devices and / or device components provided in free-standing and / or tethered configurations that decouple forces originating upon deformation, stretching or compression of a supporting substrate from the free standing or tethered device or device component.
