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 […]

Pacifier sensor detects glucose levels in babies

UCSD’s Joe Wang has developed a soft, flexible, pacifier-based biosensor that continuously monitors glucose levels in saliva to detect diabetes in babies. Until now,  continuous glucose monitoring in newborns,  available only in major hospitals, requires piercing the infant’s skin to reach interstitial fluid. The team created a proof of concept pacifier where small amounts of saliva […]

Non-invasive glucose monitoring patch

Richard Guy and University of Bath colleagues have created a non-invasive, adhesive patch, to measure glucose levels through the skin without a finger-prick blood test. The patch draws glucose from fluid between cells across hair follicles, accessed individually via an array of miniature sensors using a small electric current. The glucose collects in tiny reservoirs […]

Patch monitors diabetes compounds in sweat for 1 week

University of Texas professor Shalini Prasad has developed an adhesive sensor that measures diabetes-associated compounds in small amounts of sweat. Blood glucose levels, cortisol and interleukin-6 are detected in perspiration for one week with full signal integrity.  The device uses ambient sweat, created by the body with out stimulation. The sensor can be placed anywhere […]

Transparent, stretchable lens sensor for diabetes, glaucoma detection

UNIST professors Jang-Ung Park, Chang Young Lee and Franklin Bien, and KNU professors Hong Kyun Kim and Kwi-Hyun Bae, have developed a contact lens sensor to monitor biomarkers for intraocular pressure, diabetes mellitus, and other health conditions. Several attempts have been  made to monitor diabetes via glucose in tears.  The challenge has been poor wearability, as the electrodes […]

Apple reportedly developing non-invasive glucose monitor

CNBC’s Christina Farr has reported that Apple has been quietly developing a non-invasive, sensor-based glucose monitor.  The technology has apparently advanced to the trial stage. Diabetes has become a global epidemic.  Continuous monitoring, automatic insulin delivery, and the “artificial pancreas” are significant steps forward, meant to control the disease, and avoid its debilitating side effects. […]

Consumer wearable + medical monitor track exercise’s impact on glucose

Consumer wearables can complement medical devices by integrating activity data into a disease management strategy. Fitbit movement data will now be used with a Medtronic diabetes management tool, with the goal of users predicting the impact of exercise on glucose levels. Diabetics can monitor glucose with Medtronic’s iPro2 system continuously for 6 days. Fitbit data will […]

Diabetic retinopathy-detecting algorithm for remote diagnosis

Google has developed an algorithm which it claims is capable of detecting diabetic retinopathy in photographs.  The goal is to improve the quality and availability of screening for, and early detection of,  the common and debilitating condition. Typically, highly trained specialists are required to examine photos, to detect the lesions that indicate bleeding and fluid […]
