Researchers from MIT and the Rhode Island School of Design have developed a wearable fabric microphone that can detect and transmit soundwaves and convert them into electrical signals, reports Shi En Kim for Popular Science. “Computers are going to really become fabrics," says Prof. Yoel Fink. "We’re getting very close.”
MIT researchers have created a flexible fiber that can generate electrical impulses that are conveyed to the brain as sound, reports Miriam Fauzia for The Daily Beast. “The researchers see endless possibilities for their smart fabric,” writes Fauzia. “The obvious application is in improving hearing aids, which Fink said have trouble discerning the direction of sound, particularly in noisy environments. But the fabric could also help engineers design wearable fabrics that can measure vital signs, monitor space dust in new kinds of spacecraft, and listen for signs of deterioration in buildings like emerging cracks and strains.”
MIT researchers have developed a transparent, degradable medical dressing that could be used to help gut wounds heal more quickly and efficiently without leaking bacteria, reports Alex Wilkins for New Scientist. The researchers “designed their dressing to work like duct tape, which is only sticky on one side,” writes Wilkins. “Once it covers the wound, it quickly forms a hydrogel, an adhesive layer that can help the wound to heal.”
In an article for The Wall Street Journal about next generation technologies that can create and quantify personal health data, Laura Cooper spotlights Prof. Dina Katabi’s work developing a noninvasive device that sits in a person’s home and can help track breathing, heart rate, movement, gait, time in bed and the length and quality of sleep. The device “could be used in the homes of seniors and others to help detect early signs of serious medical conditions, and as an alternative to wearables,” writes Cooper.
Mashable reporter Emmett Smith spotlights how MIT researchers have created a new toolkit for designing wearable devices that can be 3D printed. “The researchers used the kit to create sample devices, like a personal muscle monitor that uses augmented reality,” explains Smith, “plus a device for recognizing hand gestures and a bracelet for identifying distracted driving.”
Professor Xuanhe Zhao and his colleagues have developed a new soft robotic prosthetic hand that offers the wearer more tactile control. “You can use it to grab something as thin and fragile as a potato chip, or grasp another hand in a firm-but-safe handshake,” writes Mark Wilson for Fast Company. “By design, this rubbery, air-filled hand is naturally compliant.”
Dezeen reporter Rima Sabina Aouf writes that MIT researchers have created an inflatable prosthetic hand that can be produced for a fraction of the cost of similar prosthetics. “The innovation could one day help some of the 5 million people in the world who have had an upper-limb amputation but can't afford expensive prostheses.”
Engineers at MIT have developed a soft, inflatable, neuroprosthetic hand that allows users to carry out a variety of tasks with ease, reports Emmett Smith for Mashable. “People who tested out the hand were able to carry out quite complex tasks, such as zipping up a suitcase and pouring a carton of juice.”
MIT researchers are developing an electronic skin that can withstand sweating, reports Karen Kwon for Inside Science. The researchers “punched holes on the e-skin to match the size of sweat pores and the distance between them. Then, inspired by kirigami, the team cut away even more material between two holes in an alternating pattern,” writes Kwon. The resulting pattern “could tolerate bending and stretching more than the conventional e-skin with simple holes.”
MIT researchers have developed a new stent based on kirigami, the Japanese art of cutting and folding paper. The stent “can provide localized drug delivery through needle-like projections that pop out when the stent is extended,” reports Conn Hastings for Medgadget.
A new study by researchers from MIT and BU finds that the “thin gold leaf material used to decorate picture frames or lamp bases could also be used to detect viral infections,” writes Eva Amsen for Forbes. The use of an accessible material like gold leaf means a diagnostic device made from the material “could be used in doctors’ offices or field clinics anywhere in the world, no matter how far they are from a hospital.”
In an article for Wired, Prof. Amy Moran-Thomas writes about racial bias in pulse oximeters, noting that oximeters designed to work equitably existed in the 70s. “As part of AI’s growing role in health care, a wide range of noninvasive sensors are being developed with the pulse oximeter as their model,” writes Moran-Thomas. “Without care, a coming generation of optical color sensors could easily reproduce the unequal errors for which pulse oximetry is now known across many other areas of medicine.”
7 News reporter Byron Barnett spotlights how MIT researchers are developing new face masks aimed at stopping the spread of Covid-19. Prof. Giovanni Traverso is creating reusable masks with pop-put disposable filters, and Prof. Michael Strano is developing a mask that could “destroy the virus, using a nine-volt battery to heat the mask and kill the virus before the wearer breathes it in.”
Wall Street Journal reporter Suzanne Oliver spotlights two MIT efforts to innovate the face mask. Prof. Giovanni Traverso and his colleagues are developing a reusable, silicon-rubber mask with “sensors that give feedback on fit and functionality,” while Prof. Michael Strano has designed a version that “incorporates a copper mesh heated to about 160 degrees that traps and deactivates the virus.”
Popular Mechanics reporter Kyro Mitchell explores how MIT researchers have created a biodegradable medical patch that could be used to repair internal injuries. Mitchell notes that the patch “can be easily wrapped around robotic tools like a balloon catheter and a surgical stapler and then be inserted into the patient.”
