One aspect of the invention provides a prosthetic foot including a heel member, a toe member, and an attachment member comprising a shear thickening material (STM). In one embodiment, the attachment member has a first end and a second end. The first end can be connected to the heel member, and the second end can be connected to the toe member. In another embodiment, the attachment member further comprises an elastic polymer. In one instance, the elastic polymer is impregnated with the STM. In yet another embodiment, the attachment member further comprises an elastic reservoir. The elastic reservoir can contain the STM. Alternatively, the attachment member further comprises a rigid reservoir. The rigid reservoir can contain the STM.

A system for control of a device includes at least one sensor module detecting orientation of a user's body part. The at least one sensor module is in communication with a device module configured to command an associated device. The at least one sensor module detects orientation of the body part. The at least one sensor module sends output signals related to orientation of the user's body part to the device module and the device module controls the associated device based on the signals from the at least one sensor module.

A prosthetic knee for active users has a locking head generally parallel to a vertical axis of the prosthetic knee, a chassis, and a plurality of links connecting the locking head to the chassis. The knee includes a swing control mechanism having a flexion stop connected to the chassis and arranged to control the flexion angle of the knee. The flexion stop extends outwardly from the chassis and obliquely relative to the vertical axis. The knee has an audible feedback mechanism for providing the user with information about the location of the knee. The knee may also have a block lock forming a manually activated mechanism allowing load bearing in a flexed position.

A method and an osseointegrated prosthesis system having an osseointegrated prosthesis member are provided having a monitoring system operably coupled to the osseointegrated prosthesis member configured to quantitatively assess the osseointegration of the osseointegrated prosthesis member, a wave-generating element coupled to the osseointegrated prosthesis member and configured to output guided waves along the osseointegrated prosthesis member interrogating an interface between bone and the osseointegrated prosthesis member, and a sensing system configured to sense a condition of the interface between bone and the prosthesis.

A system and method for transferring proprioceptive and/or sensory information from a prosthesis or from a sensing system disposed at a body part having poor or no sensation, to the skin of a user wearing the prosthesis or the sensing system, includes: a device for providing electrotactile feedback in the form of an electrical stimulation pattern with coding scheme for at least one input signal; and at least one multi-pad electrode configured to be positioned on a part of the body of the user. The multi-pad electrode includes a plurality of pads configured to be selectively and discretely activated/deactivated according to the predefined stimulation pattern.

A system for attachment of a device to a bone is provided. The system includes an internal axial rod with a proximal and distal end that is configured to be inserted and secured into a bone cavity's distal end. The system can also include an internal-external transfer rod with a proximal and distal end mounted into the distal end of the axial rod and a central channel extending through the transfer rod from the proximal end to the distal end and a plurality of attachment rings for attaching at least one tissue or muscle group to the transfer rod. The system also includes a bio-compatible and bio-occlusive artificial membranes (BIOCAMS) lamina, wherein the lamina includes either a polyetheretherketone (PEEK) mesh, a biocompatible polymer, a carbon fiber polymer, an artificial tissue polymer, molded donor tissue, allogenic tissue, a collagen/hyaluronic acid-based tissue, or connective tissue biosynthetic substrate material suitable as webbing.
