Ruhr University professor Sebastian Kruss, with Max Planck researchers Sofia Elizarova and James Daniel, has developed a sensor that can visualize the release of dopamine from nerve cells with unprecedented resolution. The team used modified carbon nanotubes that glow brighter in the presence of the messenger substance dopamine. Eizarova said that the sensor “provides new […]

Wearable sensor network informs transient pacemaker
John Rogers and Northwestern colleagues have developed their second generation transient pacemaker, used post cardiac-surgery or for those awaiting permanent pacemakers. The new version, still implantable, wireless, and self dissolving, works with a network of soft wearable sensors, placed around the body. The sensors continuously monitor body temperature, oxygen levels, respiration, muscle tone, physical activity, […]

MSK developed sensor detects molecular signature of cancer; compared to human scent
Mijin Kim and Daniel Heller of the Nanomedicine Lab at Memorial Sloan Kettering Cancer Center have developed an array of carbon nanotube sensors that can “sniff” cancer using AI. The human nose can detect a trillion different scents, through hundreds of olfactory receptors. The pattern which odor molecules bind to which receptors creates a kind […]

Stent + soft sensor system continuously monitors hemodynamics
Georgia Tech‘s Woon-Hong Yeo and colleagues have developed a prototype smart stent and printed soft sensor system which can wirelessly monitor blood flow through the vascular system in real-time, without batteries or circuits. The small and thin stent can be placed anywhere inside the body to continuously measure arterial pressure, pulse, and flow. When the […]

Microneedle wearable continuously monitors glucose, lactate, alcohol
UCSD Professor Joe Wang and colleagues have created a multiple biomarker monitor in the form of a painless microneedle patch, which Wang calls a “complete lab on the skin.” Glucose, lactate and alcohol levels are monitored simultaneously, in real time. Microneedles enable the direct sample of interstitial fluid, which provides a similar measure of biochemical […]

Chest sensor detects worsening asthma, respiratory disease
The RESP Sensor from Strados labs received FDA clearance for early, remote detection of lung acoustic and ventilation pattern changes to predict worsening respiratory disease. Lung sounds associated with asthma, COPD, heart failure and infectious diseases including COVID-19 are detected. Frequency of wheezing, coughing, shortness of breath, and respiratory dynamics including rate and excursion are […]
