Neural bypass restores feeding and touch in paralyzed man

A paralyzed man who was injured in 2020 can now feed himself, drink from a cup, and feel his dog’s fur thanks to a double neural bypass that uses implanted electrodes to translate intention to move from the brain to arm muscles and sensors on the fingers to relay touch back to the brain. After 35 weeks of training, his right-arm strength rose 86% and his left 62%; gains persisted even when the device is off and have endured for more than two years, highlighting durable improvements and the promise of brain–computer interfaces for paralysis.

"Temperature-Sensitive Prosthetic Limb Enhances Human Connection"

A new prosthetic limb called MiniTouch allows wearers to sense temperature, providing realistic and real-time thermal sensory feedback to amputees. The device, which does not require surgery, transmits thermal information from the fingertip of the prosthetic hand to the wearer’s residual arm, enabling them to perceive and respond to temperature. The technology has the potential to restore a full range of sensations through prosthetics, marking a significant advancement in the field of sensory feedback for artificial limbs.

"Revolutionary Prosthetic Limb Sensing Temperature Like a Real Hand"

Researchers have developed the "MiniTouch," a device that enables amputees to sense and respond to temperature, enhancing their interaction with the environment and emotional connection with prosthetic limbs. The device, which requires no surgery for integration, allows amputees to discriminate between objects of different temperatures and experience affective touch. The technology is a significant step towards fully restoring sensory experiences for individuals with limb loss, potentially improving their quality of life.

"Temperature-Sensitive Prosthetic Limb Enhances Sensory Experience and Human Connection"

Researchers have developed a prosthetic limb device called MiniTouch that allows users to sense temperature differences, enabling them to perceive warmth or coolness in their missing limb. The device, which does not require surgery, uses a temperature sensor and readily available electronics to reproduce thermal sensations on the skin of the amputee. Testing on a patient showed improved accuracy in distinguishing between objects and materials, indicating the potential for enhancing sensory feedback in artificial limbs. The team aims to create a single wearable system that can provide various sensations, such as pressure, texture, position, temperature, and wetness, through prostheses.

Closed-loop Spinal Cord Stimulation: Restoring Foot Sensory Feedback and Alleviating Phantom Limb Pain

Researchers have demonstrated the successful restoration of sensory feedback from the foot and reduction of phantom limb pain in individuals with lower-limb amputations through closed-loop spinal cord stimulation. By stimulating the spinal cord in response to pressure sensors on the sole of the foot, the study participants were able to perceive sensations in their missing limb and experience relief from phantom limb pain. This breakthrough could significantly improve the quality of life for amputees and pave the way for the development of more advanced neuroprosthetic devices.

"Exploring the Fascinating World of Octopus-Inspired Robotic Arms"

Researchers have developed a soft robotic tentacle inspired by octopuses, capable of grasping small objects in air or water. The tentacle mimics the bend propagation movement of an octopus arm and can be operated remotely using a glove that fits over one finger. The robotic tentacle consists of five segments made of soft silicone embedded with metal wires, forming an electronic network that mimics the nervous system of an octopus arm. The tentacle can expand 1.5 times its original length and incorporates sensory feedback, allowing the operator to feel the engagement of the suckers at the tip. The technology has potential applications in marine research, biomedical technology, and artificial organs.

"Revolutionary E-Skin Communicates with the Brain and Mimics Human Touch"

Researchers at Stanford University have developed an artificial electronic skin (e-skin) that can convert sensory inputs into electrical signals that the brain can interpret. The e-skin incorporates soft integrated circuits and can detect stimuli similar to natural skin, including pressure, temperature, strain, and chemicals. The e-skin operates at a low voltage and can endure continuous stretching without losing its electrical properties. This advance could facilitate the creation of prosthetic limbs with sensory feedback or advanced medical devices.

Revolutionary Bionic Technology Allows Amputees to Feel Human Touch and Temperature Sensations.

Researchers at the École polytechnique fédérale de Lausanne (EPFL) have developed a bionic technology that allows amputees to feel hot or cold sensations in their phantom hand and fingers, as well as directly on the arm, through thermal electrodes placed on the skin of their residual arm. The technology, which has been tested for more than two years, does not need to be implanted and can be worn on the skin and combined with a regular prosthetic. The researchers hope that the technology could lead to a more natural feeling of loved ones when amputees are wearing their prosthetic.
