Many wearable health sensors are uncomfortable, noticeable or distracting, especially when placed on the face. These devices can make people self‑conscious and even change the very signals they are meant to measure. Researchers at the University of Tokyo have developed […]
Invisible Skin Sensors Capture Facial and Brain Signals Without Being Seen Read More »
Wound infections often begin quietly, with bacteria entering a fresh injury and forming a protective biofilm within hours. Once this biofilm develops, infections become much harder to treat and can slow healing significantly. Researchers at the University of Bath have
Plant‑Based Wound Dressing Delivers Antibiotics Before Infection Takes Hold Read More »
Liver fibrosis is a silent condition in which the liver gradually hardens like a callus, often without obvious symptoms until serious damage has already occurred. Today, doctors usually rely on liver biopsies or expensive imaging tests to detect fibrosis, procedures
Astronauts have long faced a major challenge when dealing with injuries or illness in orbit because ultrasound has been the only practical imaging tool available. Ultrasound can be helpful, but it requires extensive training and depends on a sound‑transmitting medium,
First X‑Rays Taken in Space Could Change How Astronauts Stay Healthy Read More »
Finding the right contact lenses can be a slow and frustrating process for people whose eyes do not match standard lens shapes. Many patients with irregular corneas need rigid lenses that must be fitted over several appointments, and even then
New 3D‑Printing Method Creates Personalized Contact Lenses on Demand Read More »
Many medicines require careful dosing, yet doctors often rely on occasional blood tests that provide only brief snapshots of drug levels. This approach can make it difficult to understand how a medicine moves through the body over time. Researchers at
Wearable Microneedle Patch Could Help Monitor Medicines in Real Time Read More »
Many medical sensors used to monitor heart and muscle activity can feel stiff, uncomfortable or difficult to keep attached to the skin, especially when patients move or sweat. Engineers at the Pennsylvania State University have developed paintable electrodes that can
Paintable Electrodes Enable Flexible and Artistic Wearable Health Sensors Read More »
Treating infected wounds is difficult because the skin needs protection, cooling and antibacterial support, yet most dressings can only provide one or two of these benefits at a time. Researchers at The Hong Kong Polytechnic University and their collaborators have
Cooling Nanofiber Skin Speeds Healing in Infected Wounds Read More »
Cleaning wounds and surgical instruments is often difficult because bacteria and debris often cling to surfaces that are hard to reach with conventional methods. Researchers at the University of Illinois Urbana‑Champaign have developed a new approach that uses tiny microparticles
Ultrasound‑Activated Microparticles Provide a New Approach to Wound Cleaning Read More »
Monitoring premature infants is challenging because traditional sensors rely on wires, adhesives and repeated blood draws that can irritate fragile skin and cause stress during critical stages of development. Researchers from Tufts University and several universities in Germany have developed
