Security veins: Advanced biometric authentication through AI and infrared

Hyperspectral imaging is a technology that detects slight differences in color to pinpoint the characteristics and conditions of an object. While a normal camera creates images using red, green, and blue, a hyperspectral camera can obtain over 100 images in the visible to near-infrared light range in a single shot. As a result, hyperspectral imaging can obtain information that the human eye cannot see. Specially Appointed Associate Professor Takashi Suzuki at the Osaka Metropolitan University Center for Health Science Innovation captured images of palms of human hands using a hyperspectral camera and AI-based region of interest. Hemoglobin contained in red blood cells absorbs light, ...

Paralyzed man moves robotic arm with his thoughts

Researchers at UC San Francisco have enabled a man who is paralyzed to control a robotic arm through a device that relays signals from his brain to a computer. He was able to grasp, move and drop objects just by imagining himself performing the actions. The device, known as a brain-computer interface (BCI), worked for a record 7 months without needing to be adjusted. Until now, such devices have only worked for a day or two. The BCI relies on an AI model that can adjust to the small changes ...

Tufts scientists develop open-source software for modeling soft materials

When mechanical and structural engineers design machines, bridges, and buildings, they calculate loads, stresses, and deformation of metal, steel, concrete, glass, wood, and plastic to find the optimal geometry that bears loads with the minimum cost of material. Designing for relatively hard materials that do not deform too much is commonly handled by software that calculates and optimizes structures using mathematical models that are well understood and easily applied. But there is an expanding class of design challenges for things that incorporate soft materials—biological materials, engineered tissues, membranes, and even shape-shifting ...

AI can open up beds in the ICU

At the height of the COVID-19 pandemic, hospitals frequently ran short of beds in intensive care units. But even earlier, ICUs faced challenges in keeping beds available. With an aging American population, 11% of hospital stays included ICU stays. Artificial intelligence offers a possible solution, says Indranil Bardhan, professor of information, risk, and operations management and Charles and Elizabeth Prothro Regents Chair in Health Care Management at Texas McCombs. AI models can predict the lengths of time patients will spend in the ICU, helping hospitals better manage their beds and, ideally, cut costs. But although AI is good at predicting length of stay, ...

Are robotic hernia repairs still in the “learning curve” phase?

For an abdominal wall hernia repair, also known as a ventral hernia repair, the most common surgical approaches have been laparoscopic and open techniques. But a new approach for repairing hernias has been steadily growing in popularity: the surgical robot. Supporters of using the robot method state multiple advantages over traditional laparoscopic and open approaches, including improved surgeon ergonomics. But there may be downsides to the technology that are going undiscussed. In a research article published in JAMA Surgery, Brian Fry, M.D., M.S., a ...

New device could allow you to taste a cake in virtual reality

COLUMBUS, Ohio – Novel technology intends to redefine the virtual reality experience by expanding to incorporate a new sensory connection: taste. The interface, dubbed ‘e-Taste’, uses a combination of sensors and wireless chemical dispensers to facilitate the remote perception of taste – what scientists call gustation. These sensors are attuned to recognize molecules like glucose and glutamate — chemicals that represent the five basic tastes of sweet, sour, salty, bitter, and umami. Once captured via an electrical signal, that data is wirelessly passed to a remote device for replication. Field ...

Improving the scope of wearable monitors

By Alistair Jones SMU Office of Research – Even by the standards of medical terminology, photoplethysmography (PPG) is a mouthful. Yet it is widely used in clinical settings as a non-invasive, optical technique for measuring the oxygen saturation level in the blood, and the pulse rate, as vital signs of a patient. It is commonly encountered as a clip-on oximeter attached to a finger. First developed in the 1930s, PPG emits light to illuminate the microvascular bed of the skin. Then a photodiode, positioned alongside the light emitter, captures the reflected light, termed the PPG waveform, which ...
