Researchers at MIT have created a new text selection interface for motor impaired individuals. People with severe physical disabilities can type to communicate with others, and often activate a switch or blink an eye to indicate a letter selection in a grid of letters on a computer screen. This approach to typing is painstaking and […]

Flexible Brain-Computer Interface Array for Better Contact
Researchers at the University of California San Diego have created a brain-computer interface array featuring microneedles affixed to a flexible backing. The design allows the array to better conform to the undulating surface of the brain, permitting better contact and improved signal recording across a wide area. The technology represents an upgrade from the rigid […]
Fingertip Sensor Lets Prostheses Feel Applied Force
Researchers at the Max Planck Institute for Intelligent Systems in Germany have created a fingertip sensor that allows a robot, including a robotic prosthesis, to very sensitively gauge how much force is applied to it. The system is based on a camera that is mounted inside the rubbery robot finger. The camera observes the internal […]
Armband Provides Finger-Specific Haptic Feedback for Robotic Hand
Researchers at Florida Atlantic University have created a system for a robotic hand that provides finger-specific haptic feedback for a user, significantly improving dexterity. By delivering haptic feedback for objects grasped with the thumb, index, and little finger, the system allows users to control a robotic hand to pick up and set down two objects […]
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 by paralysis. The […]
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) […]
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 nanoparticles that provide conductivity and allow electrical […]
Personalized Exosuit Uses Ultrasound to Adapt to User’s Needs
At Harvard University a team of scientists and engineers developed an exosuit that uses ultrasound to measure muscle activity. The capability allows for rapid calibration of the suit for users’ needs. The soft wearable device continuously assists when walking or running, reducing the energy required to perform these tasks, which could be very useful for […]
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 proteins in neural tissue. The technique has […]
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, over invasive arterial […]
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 sense how they’re stretched and […]
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 challenging in terms of walking. Many […]
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 […]
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 the joints […]
Cleveland Clinic’s New Prosthetic Arm with Advanced Functionality
Researchers at the Cleveland Clinic have developed an advanced bionic arm that allows users with upper limb amputations to achieve a similar level of function as non-amputees. The system incorporates a sense of touch and movement and allows for intuitive motor control. The device is intended for users who have undergone targeted sensory and motor […]
Magnetic Beads for More Precise Control of Bionic Limbs
At MIT a team of engineers have developed a system that they claim will enhance a user’s control of a bionic limb. The technology consists of implantable magnetic beads and a series of sensors that can monitor their movement. When implanted within a muscle in a residual limb, pairs of the beads can provide information […]
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 some tactile feedback […]
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 pressure […]
Robotic Brace Measures Neck Mobility in Cancer Patients
Patients with head and neck cancer frequently require surgical removal of lymph nodes from the neck. While this is necessary, it can cause pain and stiffness that can persist for a long time after surgery. Assessing neck mobility of such patients would be useful, as it would allow doctors to identify deficits in range of […]
