Smart Stent Monitors Hemodynamics

Researchers at the Georgia Institute of Technology have developed a smart stent that can monitor hemodynamic parameters. The wireless and battery-free device can transmit the data to the outside of the body, and is powered through a wireless energy transfer system that uses magnetic fields, similar to wireless chargers that are available for many s (Read more...)

Heart Chamber on a Chip

Researchers at Boston University engineered a heart chamber on a chip that can beat by itself. The technology relies on cardiomyocytes generated from induced pluripotent stem cells and small acrylic valves that allow the fluid pumped by the chamber to come and go. The chamber is supported by a thin acrylic scaffold that aims to […]

vMap Mapping Technology for Cardiac Arrhythmias: Interview with Mike Monko, CEO of Vektor Medical

Vektor Medical, a medtech company based in San Diego, created the vMap system, a mapping solution for cardiac arrhythmias. The system is the first to identify arrhythmia sources anywhere in the heart, including the septal wall, outflow tracts, and all four chambers. The company reports that the technology takes less than three minutes to provide [& (Read more...)

Wearable Sensor Uses Kirigami to Improve Skin Contact

Researchers at Osaka Prefecture University in Japan developed a wearable and wireless electrocardiogram monitor that employs kirigami, an ancient art of folding and cutting paper, to ensure better skin contact, stretchability, and breathability. The kirigami design lets the researchers minimize the size of their sensor and the technology allows for (Read more...)

Magnetic Tentacle Robot Travels Deep into Lungs

Researchers at the University of Leeds in the UK have created a magnetic “tentacle robot” that is just 2 mm in diameter, which they hope will be able to navigate through some of the smallest airways in our lungs. At present, a bronchoscope is used to investigate the lungs, but this cannot pass into very […]

Modified Red Blood Cells for COVID-19 Vaccination

Researchers at McMaster University in Ontario, Canada created engineered red blood cells to act as a new COVID-19 vaccine technology. The cell membranes have been studded with the SARS-CoV-2 spike protein, and in experiments the researchers have conducted in mice the cells can trigger an immune response with minimal side-effects. The team reports t (Read more...)

Humanoid Robot Measures Blood Pressure with a Touch

Researchers at Simon Fraser University in Canada unveiled a humanoid robot that can measure blood pressure by touching a patient’s chest. The robot uses sensors on its fingertips to perform the measurements. Inspired by blood-sucking leeches, the dry electrode sensors infer blood pressure by combining electrocardiogram (ECG) and photoplethysm (Read more...)

The Slimmest ECG Ever Created: A Review

A couple of weeks ago, AliveCor, a leading innovator in the FDA-cleared personal electrocardiogram (ECG) technology space, announced the launch of the KardiaMobile Card. The KardiaMobile Card is the slimmest and smallest self-contained, commercially available ECG that has been created to date. It is the size of a standard credit card, and is able t (Read more...)

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 approa (Read more...)

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 (Read more...)

New Wearable Detects Respiratory Exacerbations: Interview with Dr. Maria Artunduaga, CEO of Respira Labs

Respira Labs, a medtech company based in California, created the Sylvee sensor, an adhesive patch that the user wears on their lower rib cage, and which monitors respiratory health. The device works through acoustic resonance, whereby it emits sound into the chest cavity and analyzes the echoed vibrations. The measured data provide information on l (Read more...)

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, (Read more...)
