Bionic finger, implanted electrodes, enable amputee to “feel” texture

Swiss Federal Institute of Technology and Scuola Superiore Sant’Anna researchers have developed  a bionic fingertip that allows amputees to feel textures and  differentiate between rough and smooth surfaces. Electrodes were surgically implanted into the upper arm of a man whose arm had been amputated below the elbow.  A machine moved an artificial finger, wired with electrodes,  across […]

Self-healing sensor improves “electronic skin”

Hossam Haick and Technion colleagues are developing materials to be integrated into flexible electronics that mimic the healing properties of human skin.  The goal is to quickly repair incidental scratches or damaging cuts that might compromise device functionality. The synthetic polymer can “heal” electronic skin in one day, which can improve the materials used to […]

Sensors allow more natural sense of touch in prosthetics

Stanford’s Zhenan Bao is developing technology that could restore a more natural sense of touch in prosthetics.  Her flexible, thin plastic sensors send signals to the brain that more closely resemble nerve messages of human skin touch sensors. The disruptive technology has not yet been tested on humans, and researchers still need to find a safe way to […]

Biocompatible neural prosthetics

Spinal injury patients, and those with lost limbs, sometimes have neural prosthetic devices implanted in an attempt to regain independence.  They are used for deep brain stimulation and brain controlled external prosthetics.  However, neural prosthetics are often rejected by the immune system, and can  fail because of a mismatch between soft brain tissue and rigid […]

Intent controlled prosthetic foot using myoelectric sensors

Ossur‘s sensor implant allows amputees to control  bionic prosthetic limbs with their minds.  Myoelectric sensors are surgically placed in residual muscle tissue.  Prosthetic movement is triggered via a receiver. Ossur’s existing “smart limbs”  are capable of real-time learning and automatically adjust to a user’s gait, speed and terrain.   However,  conscious thought is still required. […]
