Comparison of Ground Reaction Forces Components on Sound and Prosthetic Legs in Trans-Tibial Amputated Individuals

طب جانباز, 2016
Aims: The utilization of prosthesis not only changes the gait pattern in the patients with lower-limb amputations, but also applies asymmetrical forces on the limbs leading to disturbances. Therefore, it is very important to identify the application mode

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites

Advanced Materials Technologies, EarlyView.
Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.

Multimodal Haptic Perception Through Synergistic Nanocomposite Sensor Arrays

Advanced Materials Technologies, EarlyView.
Multi‐modal fingertip haptics are advanced through a bioinspired &vertical‐via' electronic skin architecture. A confined PDMS/MWCNT/NiNP nanocomposite, sitting at the percolation threshold, enables tactile, thermal, and magnetic sensing. A unique via‐density gradient and dedicated &Un‐Touch' reference nodes provide robust spatial resolution and signal ...

Patient satisfaction concerning implant-supported prostheses: an observational study

Brazilian Oral Research, 2015
The aim of this observational study was to assess the degree of patient satisfaction toward implant-supported prostheses. A questionnaire was used with two scales (one consisting of detailed adjectival and the other of numerical responses) regarding ...

Nickel sensitivity and the implantation of orthopaedic prostheses [PDF]

Contact Dermatitis, 1993
There is no evidence that nickel‐sensitive patients, when given a modern plastic‐to‐steel hip replacement, develop cutaneous reactions or loosening of their prostheses. However, eczema I occasionally seen with static metal prostheses and eruptions sometimes accompanied the use of the older types of joint prosthesis.

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

Advanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.
