Tissue engineers face a major obstacle when creating complex 3D‑printed or implanted biological structures: there are very few ways to monitor cell health noninvasively and in real time. Existing methods often require piercing or damaging the tissue to measure metabolite […]
Optical Sensor Particles Allow Real‑Time Tissue Health Monitoring Using Only Light Read More »
High blood pressure often develops without clear symptoms, and many patients may unknowingly have an underlying hormonal disorder that routine testing fails to detect. Researchers at the University of Bristol and collaborating institutions found that people with primary aldosteronism experience
Wearable Device Reveals Hidden Hormone Spikes Linked to High Blood Pressure Read More »
Lung diseases are difficult to study because the alveoli constantly expand and contract, and this motion influences how lung cells grow, function, and respond to inflammation. Conventional cell‑culture systems cannot reproduce this movement, and even lung‑on‑a‑chip devices often rely on
Ultrathin Artificial Lung Reproduces Alveolar Motion for Virus and Drug Studies Read More »
Gastric leaks are a serious complication that can occur after weight‑loss surgery, leading to infection, prolonged hospitalization, and repeated medical interventions. Current drainage stents used to treat these leaks were originally designed for bile ducts rather than the stomach, and
Blood draws are among the most common medical procedures in the United States, yet many patients experience delays because of a nationwide shortage of trained phlebotomists. The U.S. Food and Drug Administration has authorized a fully autonomous robotic blood‑draw device
FDA Authorizes Robotic System To Perform Blood Draws Read More »
Many amputees struggle with prosthetic devices that cannot provide meaningful sensory feedback, leaving them unable to feel temperature, pressure, or texture during everyday tasks. Existing electronic skins attempt to address this gap, but they are often expensive, difficult to customize,
Electronic Skin System Enables Prosthetics To Sense Temperature and Pressure Read More »
Pacemakers require periodic battery replacement, a process that can be risky, costly, and burdensome for patients who depend on long‑term cardiac rhythm management. Leadless intracardiac pacemakers reduce complications compared with traditional chest‑implanted models, but their batteries still occupy more than
Pacemaker Nanogenerator Harvests Heartbeat Energy To Power Itself Read More »
Patients in intensive care often experience rapid and dangerous changes in blood pressure, yet the standard method for continuous monitoring requires inserting a catheter directly into an artery. This approach provides accurate, beat‑by‑beat measurements but carries risks such as bleeding,
Wearable Sensor System Uses AI To Generate Continuous Blood Pressure Waveforms Read More »
Severe bone injuries caused by trauma, cancer, or infection often fail to heal because engineered bone tissue struggles to form the blood vessels needed to deliver oxygen and nutrients. Without vascularization, even advanced bioprinted constructs cannot mature or integrate with
Genetic Switches Enable 3D‑Printed Bone Tissue To Support Blood Vessel Growth Read More »
Spinal cord injuries often lead to permanent loss of movement, sensation, and autonomic control because damaged neural pathways can no longer carry signals between the brain and the body. Current technologies typically focus on restoring only one function at a
