We have developed two fundamental components to manufacture a prosthetic skin: a stretchable pressure sensor formed of piezoelectric elastomer/ferroelectret multilayer sandwiched between stretchable electrodes and stretchable thin-film transistors. The components are prepared and embedded in silicone rubber, a polymer, which mimics the mechanical compliance of human skin. We demonstrate the stretchability of the sensory unit. In both relaxed and stretched states, the soft sensor skin transduces kPa pressures into electrical currents in the μA range.

The realization of hand function reengineering using a manipulator is a research hotspot in the field of robotics. In this paper, we propose a multimodal perception and control method for a robotic hand to assist the disabled. The movement of the human hand can be divided into two parts: the coordination of the posture of the fingers, and the coordination of the timing of grasping and releasing objects.

Unlabelled: The bacterium is an opportunistic pathogen that can cause lung, skin, wound, joint, urinary tract, and eye infections. While is known to exhibit a robust competitive response toward other bacterial species, this bacterium is frequently identified in polymicrobial infections where multiple species survive. For example, in prosthetic joint infections, can be identified along with other pathogenic bacteria including , , and .

Midface deformities due to oncologic bony defects are often difficult to secondarily correct. The authors herein report 2 cases of secondary reconstruction of an oncological premaxillary defect using a π-shaped fibula osteocutaneous flap. The authors divided the fibula into 3 pieces and made it π-shaped to reconstruct the curvature of the premaxilla.

Background: Prosthetic socket is a key component of the prosthesis for clinical application; its performance directly affects the adaptation of the residual limb to the prosthetic socket. There are long-term and short-term volume fluctuation of the residual limb. The volume fluctuation of the residual limb will lead to the pressure mismatch at the interface of the residual limb and the prosthetic socket, which will cause a series of skin and fit problems.

In alloplastic breast reconstruction, the choice of implant positioning and the selection of periprosthetic devices is a critical and challenging decision. Surgeons must navigate between various biologic and synthetic meshes, including acellular dermal matrices (ADM). This study aimed to propose a simple selection tool for periprosthetic devices in prepectoral breast reconstruction.
