Smart Phyjamas for Monitoring Physiological Signals at Night

Researchers from University of Massachusetts at Amherst have developed a new smart pajama, dubbed Phyjama, that can track physiological signals during sleep. Their work demonstrates that the technology can reliably measure heart rate, breathing rate, and sleep position during the course of the night. One day, advances like this can be incorporated (Read more...)

Tivus Ultrasound System for Pulmonary Arterial Hypertension Gets FDA Breakthrough Designation

SoniVie, a company based in Israel, won FDA Breakthrough Device Designation for its TIVUS intravascular ultrasound system for patients suffering from pulmonary arterial hypertension (PAH). Currently there are only medications available for PAH and even those don’t do so well at improving mortality rates, so the new designation is potentially (Read more...)

Nanovolcanoes Record Electrical Activity Inside Heart Cells

The electrical activity of cardiomyocytes and other excitable cells such as neurons is studied using a number of techniques. To get details about the action potentials within the interior of the cell requires either forcefully pushing microelectrodes through the cellular barrier or using electroporation, a high voltage technique that makes temporar (Read more...)

FDA Clears First Cuff-Free Blood Pressure Monitors

The FDA has granted Biobeat, an Israeli firm, clearance for the company’s wrist watch and patch that measure blood oxygenation, heart rate, and blood pressure. Not relying on a traditional cuff allows for long-term monitoring of blood pressure, particularly in patients who have difficulty keeping track of their health parameters on their own. (Read more...)

Fully Flexible and Wireless Body Monitoring Sensors

Flexible body-worn sensors that conform to the skin have great potential for monitoring patient health, conducting long-term studies, and giving consumers a way to track their exercise and overall health. Although there have been flexible sticker-like body monitors developed in the past, they have all involved rigid electronic chips and batteries. (Read more...)

Swiss Scientists Print World’s Smallest Stent

In rare cases, some children, often still in the womb, develop urethral strictures that make it difficult or impossible to empty the bladder. Typically, a surgical procedure is performed to remove the narrowed section of the urethra, with the open ends being sewed together. This is traumatic for the children and can be difficult for […]

Ultrasound System to Charge Medical Implants

Batteries power most electric medical implants. Pacemakers, for example, use the same battery for years without recharging, but eventually have to be replaced once the charge starts to run out. There have been numerous attempts to create technology to generate electricity from within the body to power these devices. These have resulted in rather mo (Read more...)

LipoGlo Makes Bad Cholesterol Glow Inside Zebrafish

So-called “bad cholesterol” is a molecular complex of fat and protein. Specifically, the protein is Apolipoprotein-B, or ApoB, and the fat is cholesterol. While ApoB helps fat molecules to move around the blood vasculature, it is also what makes cholesterol stick to vessel walls, forming dangerous plaques that are one of the main causes (Read more...)

3D Printed Cardiac Components

Researchers at Carnegie Mellon University have developed a method to 3D print collagen and cells to form organ components, potentially paving the way for full organ printing in the future. The technique, called Freeform Reversible Embedding of Suspended Hydrogels (FRESH), involves printing collagen layer-by-layer in a bath of support gel, which all (Read more...)

Breath Analyzer for Acute Respiratory Distress Syndrome

Acute respiratory distress syndrome (ARDS) is a condition in which fluid leaks into the lungs and builds up in the alveoli within. It is a rapidly progressive condition that often leads to terminal consequences, yet it can be difficult to diagnose and monitor. Now, researchers at University of Michigan have developed a portable device that [&hellip (Read more...)

New Device Helps Deliver Accurate Chest Compressions

Chest compressions, if performed properly, can save people from cardiac arrest. Most bystanders faced with an individual requiring resuscitation fail at this task, in many cases because their compressions are too weak and are not delivered correctly. Now, researchers from the Fraunhofer Institute for Silicate Research and University of Applied Scie (Read more...)
