Abstract: Provided herein are liquid crystal polymers and elastomers configured to include a thermal circuit for creating thermal paths between various nodes of the thermal circuit including a heat source, a heat sink, and an insulated area or insulated body. The liquid crystal elastomers described herein may be configured to include portions of the thermal circuit with modified conductivities that meet specifications for the heat flows along thermal paths and for the temperatures of nodes in the thermal circuit. The liquid crystal elastomers described herein include modifiable thermal conductivities based on a selected alignment of directors of the liquid crystal elastomers. Described herein are methods for designing alignments of directors for several and different portions of the liquid crystal elastomer and methods to create various thermal circuits utilizing liquid crystal elastomers and polymers.

Abstract: A helmet for improved impact protection includes a shell and a first pad disposed within the shell. The first pad includes a first lattice structure with at least one LCE pillar. In some aspects, the helmet includes a plurality of pads. Each pad may include multiple regions. Each region of a pad may be comprised of different lattice structures, some of which contain LCE pillars and some of which do not.

Abstract: A device for a metatarsophalangeal (MTP) joint includes a body with a stem and a head. The stem may be hollow and include a plurality of perforations about its length to improve osseointegration. The head may include one or more perforations and/or one or more islands. The one or more perforations and one or more islands are configured to promote bonding the body and liquid-crystalline elastomer (LCE) that is applied to the head. The device may be inserted into bone to form an MTP joint replacement.

Abstract: Various embodiments of the present disclosure include a consumable capsule containing an active ingredient in at least one compartment movably sealed by a stimuli responsive actuator, and an activation device configured to communicate with the consumable capsule. The activation device is configured to emit a wireless signal to activate the stimuli responsive actuator of the consumable capsule, and the consumable capsule is configured to release the active ingredient into an external environment based on the activation of the stimuli responsive actuator.
