Abstract: An elastically-deformable, conductive composite using elastomers and conductive fibers and simple fabrication procedures is provided. Conductive elastomeric composites offer low resistance to electrical current and are elastic over large (>25%) extensional strains. They can be easily interfaced/built into structures fabricated from elastomeric polymers.

Abstract: A soft robot is described, including: a flexible and/or stretchable body; a common fluid pressurization unit; and a plurality of fluid chambers each embedded in the flexible and/or stretchable body and capable of fluidic connection with the common fluid pressurization unit through a pressurizing valve; wherein the pressurizing valve is capable of being activated to allow the pressurized fluid to flow from the common fluid pressurization unit into the fluid chamber to result in actuation. Methods of using the soft robot are also described.

Abstract: A soft material retractor includes at least two soft actuators, each actuator having at least one pressurizable interior space, wherein the actuator has a first flexible resting state and a second stiffer pressurized state; and a flexible sheet spanning the actuators such that the actuators can be spaced apart from each other by a distance selected to displace a volume of material of a body cavity. The retractor can be uses for holding open wounds or incisions, with trochars, or to displace anatomical features such as organs within a body cavity.
