Abstract: An elastic strain sensor can be incorporated into an artificial skin that can sense flexing by the underlying support structure of the skin to detect and track motion of the support structure. The unidirectional elastic strain sensor can be formed by filling two or more channels in an elastic substrate material with a conductive liquid. At the ends of the channels, a loop port connects the channels to form a serpentine channel. The channels extend along the direction of strain and the loop portions have sufficiently large cross-sectional area in the direction transverse to the direction of strain that the sensor is unidirectional. The resistance is measured at the ends of the serpentine channel and can be used to determine the strain on the sensor. Additional channels can be added to increase the sensitivity of the sensor. The sensors can be stacked on top of each other to increase the sensitivity of the sensor. In other embodiments, two sensors oriented in different directions can be stacked on top of each other and bonded together to form a bidirectional sensor. A third sensor formed by in the shape of a spiral or concentric rings can be stacked on top and used to sense contact or pressure, forming a three dimensional sensor. The three dimensional sensor can be incorporated into an artificial skin to provide advanced sensing.

Abstract: In at least some aspects, the present concepts include a method for configuring an assistive flexible suit including the acts of outfitting a person with an assistive flexible suit, monitoring an output of at least one sensor of the assistive flexible suit as the person moves in a first controlled movement environment, identifying at least one predefined gait event using the output of the at least one sensor, adjusting an actuation profile of the at least one actuator and continuing to perform the acts of monitoring, identifying and adjusting until an actuation profile of the at least one actuator generates a beneficial moment about the at least one joint to promote an improvement in gait. The at least one controller is then set to implement the actuation profile.

Abstract: A soft brace to prevent injury to one or more target joints or body segments is disclosed. The soft brace includes one or more tensile elements configured to limit motion of one or more target joints based on placement of the one or more tensile elements relative to the one or more target joints such that the placement and tension of each of the one or more tensile elements provides resistance against motion of the one or more target joints; one or more soft tissue anchors positioned on a body around the one or more target joints, the one or more anchors being configured to anchor one or more of the one or more tensile elements to the body to provide force distribution relative to the one or more target joints; and wherein at least one of the one or more tensile elements is routed in parallel with the approximate center of rotation of at least one of the one or more target joints.
