Atrial fibrillation-detecting ring

Eue-Keun Choi and Seoul National University colleages have developed an atrial fibrillation detecting ring, with similar functionality to AliveCor and other watch-based monitors. The researchers claim that the performance is comparable to medical grade pulse oximeters. In a study, Soonil Kwon and colleagues analyzed data from 119 patients with AF who underwent simultaneous ECG and photoplethysmography […]

3D printed, vascularized heart, using patient’s cell, biological materials

Tel Aviv University professor Tal Dvir has printed a 3D vascularized engineered heart, including cells, blood vessels, ventricles and chambers,  using a patient’s own cell and biological materials. A biopsy of fatty tissue was taken from patients. Cellular and a-cellular materials were separated. While the cells were reprogrammed to become pluripotent stem cells, the extracellular […]

Adhesive emergency response sensors

VitalTag by Pacific Northwest National Laboratory is a chest-worn sticker that detects, monitors and transmits blood pressure, heart rate, respiration rate and other vital signs, eliminating the need for multiple medical devices. It is meant for emergency responders to quickly assess a person’s state. Additional sensors are worn on the finger, and in the ear. Data […]

Small ultrasound patch detects heart disease early

Sheng Xu, Brady Huang, and UCSD colleagues have developed a small, wearable ultrasound patch that  monitors blood pressure in arteries up to 4 centimeters under the skin.  It is meant to detect cardiovascular problems earlier, with greater accuracy Applications include continuous blood pressure monitoring in heart and lung disease, the critically ill, and those undergoing […]
