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 […]

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 […]

Touch sensors enable speech and sound to be understood

Amir Amedi and Reichman University colleagues have released a study describing touch-based technology to help people understand speech and sound – and to detect their location in the future. The sensory substitution device can deliver speech simultaneously through audition and as fingertip vibrations which correspond to low frequencies extracted from the speech input. 40 non-native-English-speaking […]

Hopkins developed saliva sensor improves speed and accuracy of COVID detection

David Gracias and Ishan Barman at Johns Hopkins have developed a COVID 19 sensor which provides fast and accurate results using a drop of saliva placed on a device. No additional chemical modifications like molecular labeling or antibody functionalization are required, which could allow the sensor to be used in wearable devices. Current PCR tests […]

Zhenan Bao Stanford Skin Inspired Electronics

Zenan Bao further develops stretchable, potentially reshapeable, skin inspired electronics

Stanford’s Zhenan Bao and team have developed a stretchable, potentially reshapeable, wearable display that can allow a new way of interactive human-machine interface. “We can see the image and interact with it, and then the display can change according to our response” said Bao in a Stanford interview. The display is made entirely of stretchy […]
