Finger Clip for Blood Pressure Monitoring

At the University of Missouri a team of researchers developed a custom finger clip device that can continuously measure a variety of vitals, including blood pressure. The novel device represents a new way to measure vitals, and contains two commercial photoplethysmography (PPG) sensors that operate at two different points on the finger. This approach allows […]

Pop-Up Sensors Measure Electronic Signals in Cardiac Cells

Researchers at University of California San Diego have developed a tiny ‘pop-up’ sensor that can measure the electronic signals propagating inside cardiac cells. The technology consists of tiny spike-like protrusions that can penetrate cell membranes without causing damage, and which can detect electrical signals within individual cells and between cells in 3D tissue samples. The […]

O2Ring Keeps an Eye on Your Blood Oxygen Level: A Medgadget Review

We have all been living through a life-altering pandemic. As a result, words such as “oxygenation” and “pulse oximetry” have become mainstream and the general public has increased the use of pulse oximeters. This should come as no surprise since hypoxia (i.e., low blood oxygen level) is one of the hallmarks of COVID-19 pneumonia. Today, […]

Wireless Blood Pressure and Hemodynamic Monitoring: Interview with Jeff Pompeo, CEO, Caretaker Medical

Caretaker Medical, a company based in Virginia, developed the VitalStream wireless patient monitor, and the company recently announced that the device has received FDA clearance. The technology is intended to improve on traditional blood pressure cuffs that provide only a snap-shot of blood pressure data, while being an alternative, in many cases, over invasive arterial […]

POEMS Electro-Optical Cardiac Stimulator to Study Arrhythmias

At the University of Bern in Switzerland, researchers have developed the Panoramic Opto-Electrical Measurement and Stimulation (POEMS) system, which allows them to conduct advanced optogenetic experiments with mouse hearts. The device, which contains a volume into which a mouse heart can be placed, lets the Swiss team stimulate various cell types using light, and then […]

Magnetoelastic Patch Turns Body Motion Into Electricity

A team of scientists at University of California Los Angeles created a magnetoelastic device that can generate electricity from movements of the body, including the movements caused by the pulse at the wrist. The patch-like device may help to power medical wearables or implantable sensors, and may function as a waterproof heart rate monitor in […]

Carbon Nanotube Thread Lets Clothes Monitor Health

Researchers at Rice University managed to create flexible carbon nanotube fibers that can be incorporated into clothing to function as wearable health monitors. The new thread is highly conductive, but it is washable and strong, allowing it to function as an unobtrusive component of clothing. So far, the researchers have incorporated the fibers into a […]

Cracking Calcium in Arteries Using Sound Waves: Interview with Shockwave Medical’s Scott Shadiow

Shockwave Medical, a medtech company based in California, has developed a technique called intravascular lithotripsy, which involves delivering sonic waves to calcified plaque in an artery in much the same way that sound waves have been used to treat kidney stones for many years. The idea is to safely crack the calcified deposits so that […]

Photoacoustic Carbon Nanotubes Reveal Dangerous Atherosclerotic Plaques

Researchers at Michigan State University have developed a system that allows the imaging and identification of inflamed atherosclerotic plaques, which are considered to be at risk of rupture. Their system involves administering carbon nanotubes that are preferentially taken up by macrophages and monocytes, which tend to accumulate at inflamed plaques. The researchers then illuminate the […]
