David Baker, Fiorenzo Omenetto, and University of Washington and Tufts colleagues have developed a garment-printed biopolymer sensor which detects bacteria, toxins, and dangerous chemicals. To work, a chemical activator must be sprayed after potential exposure. If the target is present, the sensor generates light. The intensity of emitted light provides a quantitative measure of the […]

Small sticker-sensor continuously analyzes breath for broad health monitoring
Heibei University, Tianjin Hospital, Beihang University, and Penn State researchers have developed an under nose-worn, stretchable, skin-friendly, waterproof sensor to analyze breath for health monitoring. It could be use for multiple-condition screening, asthma and COPD management, or environmental hazard sensing, among other applications. The functional gas sensor, in a moisture-resistant membrane, can operate in humid […]
Remote, non-invasive pregnancy monitor tracks uterine activity
Uterine activity monitoring is essential to pregnancy management. Current methods are either invasive, or their accuracy is compromised by obesity, maternal movements, or belt positioning. Pregnancy-monitoring company Nuvo has published a study showing that their cardiac-derived algorithm for uterine monitoring was more accurate than TOCO standard of care in 150 patients. This remote, non-invasive detection […]
Sensor jumpsuit monitors infant motor abilities
Sampsa Vanhatalo, Manu Airaksinen and University of Helsinki colleagues have developed MAIJU (Motor Assessment of Infants with a Jumpsuit,) a wearable onesie with multiple movement sensors which they believe is able to predict a child’s neurological development. In a recent study, 5 to 19 month-old infants were monitored using MAIJU during spontaneous playtime. Initially, infant […]
Continuous, cuffless blood pressure monitoring via graphene tattoo
Deji Akinwande, Roozbeh Jafari, and UT Austin colleagues have developed an electronic wrist tattoo that can be worn for hours and deliver highly accurate, continuous blood pressure measurements. This can provide a much clearer picture of a person’s health than occasional, cuff based measurements at a physicians office, or at home. Smart watches are not […]
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 […]
