Researchers at Pennsylvania State University said they developed a new ferroelectric polymer that could convert electrical energy into mechanical strain. Such a polymer could offer potential for applications in medical devices, advanced robotics and precision positioning systems. The team says that mechanical strain represents an important property for an actuator. Traditionally, these actuator materials were…

Engineers at MIT say they developed a new technology that can control neural circuits connecting the gut and the brain. Using fibers embedded with sensors, plus light sources for optogenetic stimulation, the researchers demonstrated this control in mice. The study showed that they could induce feelings of fullness or reward-seeking behavior by manipulating cells of…

Researchers at George Washington University recently tested a method for remotely driving a miniature video capsule into problem areas of the stomach. Medical technology company AnX Robotica created the capsule endoscopy system used in the study, called NaviCam. The company also funded the research. Physicians can direct the capsule to potential problem areas to visualize…

University of California San Diego engineers have prototyped an inexpensive device that clips onto a smartphone to monitor a user’s blood pressure. The 3D-printed device uses the smartphone’s camera and flash paired with an algorithm on an app to take systolic and diastolic blood pressure readings. “We’ve created an inexpensive solution to lower the barrier…

BBy, a healthtech company revolutionizing hospitals’ breast milk storage and administration process, introduces its food device that condenses breast milk to a powder, maintaining the crucial bioactive components that make breast milk the best infant nutrition. BBy is disrupting a 70-year-old process in which hospitals have stored and administered donor breast milk in freezers, wasting…

Researchers at the University of Hawaiʻi at Mānoa College of Engineering say they developed a 3D-printed, wearable sweat sensor. Called the “sweatainer,” the device harnesses the power of additive manufacturing to enable a new type of wearable sweat sensor. The researchers say the small, wearable device — similar in size to a child’s sticker —…

Researchers at the University of Illinois developed “smart” coatings for orthopedic implants that can monitor strain on the devices. These coatings monitor strain to provide early warnings of implant failures while killing infection-causing bacteria. They integrate flexible sensors with a nanostructured antibacterial surface. Researchers say they received inspiration for the surface from the wings of…

Researchers say a soft robot inserted through a tiny hole in the skull could offer effective brain monitoring and treatment.
