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 […]

Wireless,biodegradable, flexible arterial-pulse sensor monitors blood flow

Zhenan Bao and colleagues have developed a wireless, battery-free, biodegradable sensor to provide continuous monitoring of blood flow through an artery.  This could provide critical information to doctors after vascular, transplant, reconstructive and cardiac surgery, with out the need for a visit. Monitoring the success of surgery on blood vessels is difficult, as by the […]

3D-printed, bluetooth-controlled ingestible capsule delivers drugs, senses environment

MIT’s Bob Langer and Giovanni Traverso have developed a 3D-printed, wirelessly-controlled, ingestible capsule that can  deliver drugs, sense environmental conditions, or both.  It can reside in the stomach for a month.  Data is sent to a user’s phone, and instructions from the phone are sent to the device.  The sensor could also communicate with other wearable […]
