Sensors 3D printed directly on lungs, heart could be used with surgical robots to diagnose, monitor disease

Michael McAlpine and University of Minnesota colleagues used 3D printing and motion capture technology to print electronic sensors directly on organs that are expanding and contracting, such as the heart and lungs. This could be used to diagnose and monitor the lungs of patients with COVID-19. This builds on the team’s technique which enabled the […]

Organic electronic patch + algorithm continuously monitor multiple COVID symptoms

Northwestern and University of Illinois researchers have partnered to combine a COVID symptom-detecting wearable with a method to organize and analyze the massive data sets required to accurately show disease progression. The technology will be used in hospitals and nursing homes, to monitor both patients and healthcare workers, to identify contagion early in an effort […]

AirPod light sensors for health monitoring

A source has told DigiTimes that Apple supplier ASE Technology will manufacture ambient light sensors for AirPods. This could be used to monitor step count, head movement, and heart rate. It could also track blood oxygen levels — a key metric in detecting COVID-19. The shift from consumer-grade to less-obtrusive medical-grade health monitoring at scale […]

3D-printed, remote-controlled lab on chip for quicker, more accurate monitoring

Imperial College’s Martyn  Boutelle has developed a 3D printed, remote-controlled Lab on a Chip for real-time monitoring with improved personal care. Previous ‘Lab on a Chip’ devices have required large external support systems. Sensor deterioration over time inhibited their clinical effectiveness. The device can monitor chemical fluctuations, giving quicker and more accurate results, and potentially […]

Tiny fiber optic sensor monitors blood flow in real-time

John Arkwright and Flinders University colleagues have developed a tiny, low cost, fiber-optic sensor to monitor blood flow through the aorta in real-time.  The goal is continuous monitoring during prolonged intensive care and surgical procedures.  Current blood flow measurement, using ultrasound or thermo-dilution,  is intermittent, averaging every 30 minutes. The device is inserted through a […]

Sensor glove identifies objects

MIT’s Subramanian Sundaram has developed a sensor glove that identifies objects through touch.  This could improve assistive robot performance and enhance prosthetic design.The cheap “scalable tactile glove” includes 550 tiny, pressure-capturing sensors.  A neural network uses the data to classify objects and predict their weights.  No visual input is required. In a Nature paper, the system […]

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 […]

Glutamate sensor could predict migraines, monitor CNS drug effectiveness

Riyi Shi and Purdue colleagues have developed a tiny, spinal cord-implanted, 3D printed sensor that quickly and accurately tracks glutamate in spinal trauma and brain disease. The goal  is to monitor drug effectiveness, and predict migraine headaches in humans, although it has only been tested on animals. Glutamate spikes are often missed.  Damaged nerve structures allow glutamate […]

Wireless, skin-like sensors monitor baby heart rate, respiration, temperature, blood pressure

John Rogers and Northwestern colleagues have developed soft, flexible, battery-free, wireless, skin-like sensors to replace multi wire-based sensors that currently monitor babies in hospitals’ neonatal intensive care units.  The goal is to enable more accurate monitoring, and unobstructed physical bonding. The dual wireless sensors monitor heart rate, respiration rate and body temperature — from opposite […]
