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 u (Read more...)
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 int (Read more...)
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 […]

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 plaqu (Read more...)
Pressure-Sensing Glove to Aid in Stroke Recovery
Researchers at MIT created a sensing glove that can detect small pressuref changes along its surface when a wearer grasps something. The glove is threaded with tiny pressure sensors, which are studded with micropillars that create changes in an electrical signal when they bend and deform. This provides an incredibly sensitive measurement of tactile (Read more...)
Remote Monitoring for Cardiac Patients: Interview with Dr. Waqaas Al-Siddiq, CEO of Biotricity
Biotricity, a medtech company based in California, developed the Bioflux system, a mobile cardiac telemetry device. The system is a three channel ECG monitor, and it enables continuous data collection and data transmission to a call center in the case of anomaly detection. If the detected issue is considered to be serious, a clinician can [… (Read more...)
Ultrasound Patch Monitors Blood Flow
Researchers at the University of California San Diego created an ultrasound patch that can measure blood flow in vessels as deep as 14 cm within the body. The stretchy patch can be applied to the skin and may help clinicians to monitor and diagnose various conditions, including blockages that could cause an infarct. The patch […]
Heart Model Simulates Mechanical Load on Cardiac Tissues
Researchers at Carnegie Mellon University, along with collaborators in the Netherlands, have developed a heart model consisting of engineered cardiac muscle tissue that is attached to an elastic material. The design allows the team to mimic the mechanical forces experienced by heart tissue in the body, which should provide them with more accurate d (Read more...)
AI Powered Health Assistant for Seniors: Interview with Ryan Howard, CEO of 100Plus
100Plus, a California medtech company, created a suite of remote patient monitoring technologies. These include a digital weight scale, blood pressure cuff, thermometer, and blood glucose monitor. The company recently launched Ava, an AI powered healthcare assistant that is specifically intended for senior patients who may not be tech savvy or as o (Read more...)
Aortic Occlusion to Enhance Blood Flow to Brain and Heart: Interview with Habib Frost, CEO of Neurescue
Neurescue, a medtech company based in Denmark, created the NEURESCUE system, a balloon catheter designed to occlude the aorta, resulting in a significant increase in blood flow to the heart and brain. The mechanism is intended to provide emergency treatment for patients suffering a hemorrhage or cardiac arrest. Both hemorrhage and cardiac arrest re (Read more...)
Battery-Free Wireless Pacemaker Dissolves Post Treatment
Researchers at Northwestern University and collaborators have developed a temporary cardiac pacemaker that dissolves away in the body into harmless byproducts. The technology avoids the need for leads penetrating the skin as well as follow-up procedures to remove a pacemaker. The device could make temporary pacemaker placement a safer and more conv (Read more...)
Battery-Free Smart Fabrics to Monitor Health
Researchers at Purdue University have developed a technique to create smart garments that can harvest electrical power from nearby Wi-Fi networks and radio waves in a process known as magnetic resonance coupling. This power can then be used to energize on-board electrical systems, including body monitors. The fabrics are water repellent, breathable (Read more...)
