  • Publication number: 20230294307
    Abstract: Certain examples are directed to an apparatus having a stretchable synthetic membrane material and series of patterned conductive or semiconductive sections. The stretchable synthetic membrane material may be provided with the series of patterned sections being integrated in or against the material (e.g., on similarly-configured robotic digits operating as a pair). One or more of these sections are electrically coupled to sensor circuitry which may also be secured to or embedded in the material. As the apparatus moves relative to an external object, various environmental parameters may be sensed via at least one sensor as the object and the digit(s) approach one another. Depending on how the sensor circuitry is configured, such parameters may include one or more of proximity, capacitance, temperature, impedance, contact with the object, and movement of the robotic member relative to the external object.

  • Publication number: 20230065894
    Abstract: Periodic placement of directional dynamic bonding units along a flexible polymer backbone enables the formation of large supramolecular structures during strain. These structures, which form due to the alignment of stretched backbone chains, lock the stretched chains in their elongated state due to the formation of the directional dynamic bonds. Application of an appropriate stimulus (i.e., heat or light) weakens the dynamic bonds and enables the elongated chains to retract, performing measurable work and enabling the use of these structures as polymer actuators. Importantly, the high strength of the dynamic bonds enables a large amount of entropic energy to be stored in the elongated chains, enabling the polymer to achieve a large actuation force during recovery.

  • Publication number: 20230067079
    Abstract: Next-generation wearable electronics require enhanced mechanical robustness and device complexity. Besides previously reported softness and stretchability, desired merits for practical use include elasticity, solvent resistance, photo-patternability and high charge carrier mobility. The present embodiments provide a molecular design concept that simultaneously achieves all these targeted properties in both polymeric semiconductors and dielectrics, without compromising electrical performance. This is enabled by covalently-embedded in-situ rubber matrix (iRUM) formation through good mixing of iRUM precursors with polymer electronic materials, and finely-controlled composite film morphology built on azide crosslinking chemistry which leverages different reactivities with C—H and C?C bonds. The high covalent crosslinking density results in both superior elasticity and solvent resistance.

  • Publication number: 20230036244
    Abstract: The present embodiments relate to lithium-based batteries, and particularly to coordinated solvent molecules that can increase the ionic conductivity of the electrolyte without undermining its non-flammability. Some embodiments include a liquid-state polymer electrolyte composed of LiFSI salts, Dimethoxyethane (DME) solvents, and polysiloxane tethered with ion solvating moieties. DME coordinates with both the salt and the polymer, while together with the salt, they synergistically plasticize the polymer to increase the ionic conductivity. The resulting non-flammable polymer electrolyte has a room temperature ionic conductivity of 1.6 mS/cm and a wide operation window of 25-100° C. Benefiting from its liquid nature, the electrolyte can pair with commercially available electrodes without further cell engineering. Embodiments can extend the ionic conductivity range of polymer electrolytes and provide a new design pathway for next generation safe and manufacturable electrolytes.
