Inflatable Prosthetic Hand with a Sense of Touch

Researchers at MIT and Shanghai Jiao Tong University created an inexpensive robotic hand intended for use by upper limb amputees. The device is more like a soft robot than previous robotic prostheses, and includes inflatable components and pneumatics, making it lightweight and inexpensive. Excitingly, the hand is equipped with sensors and provides (Read more...)

Pressure-Sensing Glove to Aid in Stroke Recovery

Researchers at MIT created a sensing glove that can detect small pressuref changes along its surface when a wearer grasps something. The glove is threaded with tiny pressure sensors, which are studded with micropillars that create changes in an electrical signal when they bend and deform. This provides an incredibly sensitive measurement of tactile (Read more...)

Artificial Skin Bruises Like The Real Thing

Researchers at the Chinese University of Hong Kong have developed an artificial skin that can effectively indicate if damage has occurred, in the same way that our skin bruises naturally. The new skin is made using an ionic hydrogel, and demonstrates changes in electrical signaling when it is deformed. It also produces a purple color […]

Brain Stimulation Lets User Feel Robotic Arm

Researchers at the University of Pittsburgh have demonstrated that providing direct sensory feedback into the brain dramatically enhanced an impaired patient’s control of a robotic arm. The arm was operated through a brain-computer interface, but the system also included brain implants in an area of the brain responsible for sensory feedback. (Read more...)

Wireless Sensor Measures Deep Tissue Oxygen Levels

Researchers at the University of California, Berkeley have developed an ultrasound-powered implantable sensor that can measure oxygen levels in tissues deep within the body and transmit these data to an external device. The technology could be useful in monitoring transplant viability or oxygen exposure in preterm infants. It also has potential to (Read more...)

Tunable Vibrations Could be Key to Reducing Lower Back Pain

Researchers at the Nagoya Institute of Technology in Japan have developed a device that can diagnose and help to correct postural instability leading to back pain. The technique involves using vibration to stimulate sensory receptors that help the brain to perceive the position of the body in space, which is known as proprioception. The approach [& (Read more...)

mRNA Delivery System Protects Neurons After Stroke

Researchers at the Tokyo Medical and Dental University have developed a way to deliver therapeutic mRNA to the brain, in this case to produce brain-derived neurotrophic factor (BDNF) which can protect neurons from ischemia. The researchers hope that the treatment could help patients who have suffered a stroke to achieve better outcomes by reducing (Read more...)

Silver-Hydrogel Composite for Bioelectronic Applications

Researchers at Carnegie Mellon University have developed a silver-hydrogel composite that can conduct electricity, which looks promising for use in a variety of bioelectronics applications. These include skin mounted electrodes for neuromuscular stimulation that may be helpful in treating muscular disorders or other motor issues. Soft materials are (Read more...)

Skin-Like Sensor for Fine Control of Prosthetic Arms

Researchers at the City University of Hong Kong have developed a soft sensor for sensitive measurement of shear forces applied to its surface. When attached to robotic grippers, the tactile sensing allows for fine control of grasped objects, enabling the robot to perform impressive feats, such as threading a needle and gripping an egg without [&hel (Read more...)

Electrical Stimulation for Improved Function Post-Spinal Cord Injury: Interview with Dave Marver, CEO, ONWARD

You may have seen an article Medgadget published recently about a minimally invasive neuromodulation technology that has shown significant promise in improving arm and hand function in patients with spinal cord injuries. The technology, called the ARC system, has been developed by ONWARD, a medtech company started by researchers at the Swiss Federa (Read more...)

Brain-Machine Interface and Exoskeleton Improve Stroke Rehab

Stroke rehabilitation as a field of research holds great promise in improving how patients recover. Unlike other organs, the brain’s neuroplasticity allows it to functionally reshape itself in beneficial ways. But it doesn’t do it on its own, so targeted interventions that require patient participation are key to optimal outcomes. There (Read more...)

Implantable Bladder Wrap for Improved Urinary Control

Researchers at Penn State have developed an implantable device that coils around the bladder to detect when the bladder is full and assist with emptying it by contracting on-demand. The device is intended to treat underactive bladder, a condition in which incomplete bladder emptying leads to irregular and uncomfortable urination. “Researchers (Read more...)
