Sensors monitor physiological variables post vaccine

Wearable sensors could improve clinical trials by enabling earlier identification of abnormal reactions. Currently, vaccine safety in clinical trials is primarily determined by participants’ subjective self-reporting. Dan Yamin, Yiftach Gepner, and Tel Aviv University colleagues used a chest patch sensor to monitor various health indicators in 160 participants, before and after receiving the Pfizer BioNTech […]

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 […]

Candy sensor prototype to monitor electrolytes, ovulation, kidney function through saliva

Korea University professors Beelee Chua and Donghyun Lee have developed a health monitoring sensor using saliva collected from a Tootsie Roll candy to detects salt and electrolyte levels, and monitor ovulation status and kidney health. The easily accessible, low-waste sensor is simply licked. To make the prototype sensor, a Tootsie roll was flattened and crevices […]

Joe Wang fingertip glucose sensor

Wang’s fingertip sweat sensor detects glucose levels

UCSD’s Joe Wang has developed a totally noninvasive sensor and algorithm to detect glucose levels from sweat on the fingertip. The painless, rapid, and accurate system could revolutionize diabetes management. The systemcombines a simple touch-based fingertip sweat electrochemical sensor with a new algorithm that addresses for personal variations toward the accurate estimate of blood glucose […]

“Ambient intelligence” monitoring to prevent medical errors, send alerts

Stanford’s Fei Fei Li, Arnold Milstein and albert Haque have developed AI and sensor based “ambient intelligence” protocols to prevent medical errors and improve outcomes. Applications include alerting clinicians and visitors when they fail to sanitize their hands before entering a hospital room; monitoring the elderly for behavioral clues of impending health crises; prompting caregivers, […]

Electrostatic and electrochemical sensors rapidly detect airborne viruses

Jang Jae-sung and Ulsan colleagues have developed a method to quickly and accurately detect airborne viruses, to inform public health and quarantine efforts. Electrostatic force captures and condenses viruses in the air, and a paper electrochemical sensor checks samples for antigens and virus antibodies. Liquid particles as small as 1 micrometer have been successfully collected. […]
