Wearable Sensors Track Hand Use in Amputees

Researchers at the University of Missouri-Columbia have developed a system to track hand use in people with a hand prosthesis or patients who have undergone a hand transplant. The technology tracks movement in the hands and arms, and helps to monitor how people use their hands in everyday life. Such data could help to guide […]

Thought-to-Text Brain-Computer Interface: Interview with Florian Solzbacher, Chairman of Blackrock Neurotech

Blackrock Neurotech, a medical technology company based in Salt Lake City, created a suite of brain-computer interface systems with the goal of empowering patients to have increased independence and quality of life. This latest technology aims to restore written communication in patients who have difficulties in this regard, such as those affected (Read more...)

Voxel-Based Technique to Streamline Bioprinting

At the University of Virginia researchers developed a new bioprinting technique based on voxels. Voxels are 3D cubes that form basic building blocks in computer graphics, similar to what pixels are for 2D, and have been popularized by games such as Minecraft. The new technique involves printing discrete spherical blobs of bioink (as the voxels) [&h (Read more...)

Washable Fabric Measures Electrical Activity of Muscles

Researchers at the University of Utah engineered a wearable fabric that can function as a biosensor, measuring electrical activity of muscles. The technology could be useful for physical rehabilitation, allowing clinicians and physical therapists to monitor patients’ progress. The fabric contains a network of silver flakes and gold nanopartic (Read more...)

Synthetic Peptides Jump Around to Repair Spinal Injuries

Researchers at Northwestern University have developed an injectable therapeutic that consists of synthetic peptide sequences intended to regenerate spinal tissue. The team designed the material so that it would allow the peptides to ‘dance,’ with such movements increasing the chance that they will find and interact with receptor protein (Read more...)

Wireless Blood Pressure and Hemodynamic Monitoring: Interview with Jeff Pompeo, CEO, Caretaker Medical

Caretaker Medical, a company based in Virginia, developed the VitalStream wireless patient monitor, and the company recently announced that the device has received FDA clearance. The technology is intended to improve on traditional blood pressure cuffs that provide only a snap-shot of blood pressure data, while being an alternative, in many cases, (Read more...)

Robotic Textiles for Breathing Recovery

Researchers at MIT, alongside collaborators from Uppsala University and KTH Royal Institute of Technology in Sweden, developed a ‘robotic textile’ that consists of an array of actuatable fibers. The fiber actuators are powered using compressed air, and can perform an impressive array of movements. Garments made using such fibers can sen (Read more...)

Exoskeleton Helps Above-Knee Amputees to Walk

Researchers at the University of Utah built an exoskeleton that can ease walking for people with above-knee amputations. The new system, which uses an electromechanical actuator attached to the thigh and AI to adapt to each person’s walking style, significantly reduces energy consumption for users. Above-knee amputations are particularly chal (Read more...)

EvoWalk Digital Therapy Platform: Interview with Pierluigi Mantovani, CEO at Evolution Devices

Evolution Devices, a company based in California, created a functional electrical stimulation device to assist people with foot drop to walk more freely. Foot drop is caused by muscle weakness/paralysis, and those affected struggle to lift the front part of their foot, which makes walking difficult and can lead to falls. The product is called [&hel (Read more...)

Algorithm Helps Rehab Robots to Move Naturally

Researchers at the Shibaura Institute of Technology in Japan have developed a control algorithm for rehabilitation robots that ensures that they move naturally during rehab sessions. The control system accounts for the angles the joints in a human arm naturally make while performing various activities, and won’t let the robot attempt to bend (Read more...)

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...)
