  • Patent number: 11904585
    Abstract: The invention relates to an adhesive system comprising a fabricated structure having alternating regions that are unpatterned and patterned along its longitudinal length. Patterned regions have at least one subregion with a non-linear cut relative to the transverse direction across the width of the structure. The geometry, location of the subregion(s), number of nonlinear cuts, and other parameters allow tuning as well as pinpoint programming of the adhesive properties either along the entire width and length or the strip or just at pinpointed subregions of the strip. Such tuning can include not only adhesive strength, but its adhesive strength in certain peeling directions.

  • Patent number: 11732172
    Abstract: A method for synthesizing a thermally conductive and stretchable elastomer composite comprises mixing liquid metal and soft material (e.g., elastomer) in a centrifugal or industrial shear mixer under conditions such that the liquid metal forms microscale liquid metal droplets that are dispersed in the soft elastomer. Liquid metal-embedded elastomers, or “LMEEs,” formed in this manner dramatically increase the fracture energy of soft materials up to 50 times over an unfilled polymer. This extreme toughening is achieved by means of (i) increasing energy dissipation, (ii) adaptive crack movement, and (iii) effective elimination of the crack tip. Such properties arise from the deformability and dynamic rearrangement of the LM inclusions during loading, providing a new mechanism to not only prevent crack initiation, but also resist the propagation of existing tears for ultra-tough, highly functional soft materials.

  • Patent number: 11729904
    Abstract: An efficient fabrication technique, including an optional design step, is used to create highly customizable wearable electronics. The method of fabrication utilizes rapid laser machining and adhesion-controlled soft materials. The method produces well-aligned, multi-layered materials created from 2D and 3D elements that stretch and bend while seamlessly integrating with rigid components such as microchip integrated circuits (IC), discrete electrical components, and interconnects. The design step can be used to create a 3D device that conforms to different-shaped body parts. These techniques are applied using commercially available materials. These methods enable custom wearable electronics while offering versatility in design and functionality for a variety of bio-monitoring applications.

  • Patent number: 11682276
    Abstract: Soft-matter technologies are essential for emerging applications in wearable computing, human-machine interaction, and soft robotics. However, as these technologies gain adoption in society and interact with unstructured environments, material and structure damage becomes inevitable. A robotic material that mimics soft tissues found in biological systems may be used to identify, compute, and respond to damage. This material includes liquid metal droplets dispersed in soft elastomers that rupture when damaged to create electrically conductive pathways that are identified with a soft active-matrix grid. These technologies may be used to autonomously identify damage, calculate severity, and respond to prevent failure within robotic systems.
