Wearable patch monitors lactate, glucose, and pH in sweat
Northwestern’s John Rogers has developed a wearable, sweat analyzing patch. The flexible microfluidic device uses colorimetric biochemical assays and integrates smartphone image capture analysis to monitor lactate, glucose, chloride ion concentrations, and pH. The wearable, with sports, military, and disease monitoring applications, can be adapted to test tears and saliva. Professor Rogers will be a…

Implanted sensors predict heart failure events
Penn State’s John Boehmer used Boston Scientific’s HeartLogic sensors (retrofitted in already implanted devices) to track heart failure in a study of 900 patients. The goal was continuous monitoring and early event detection and prevention. Currently, heart failure is (not very successfully) managed by monitoring weight and reported symptoms. One in five patients are readmitted within 30…

Tiny sensor monitors the heart, recognizes speech, enables human-machine interfaces
Northwestern professor John Rogers has released a paper detailing his latest tiny, wearable, flexible, highly accurate health sensor, which monitors the heart, recognizes speech, and can enable human-machine interfaces. Professor Yonggang Huang is the corresponding author. The soft, continuous monitor adheres to any part of the body, detecting mechanical waves that propagate through tissues and fluids…

Fully transparent, glucose monitoring contact lens
Oregon State’s Greg Herman has developed a transparent sensor to monitor glucose (via tears) in a contact lens. The device could also be used to control insulin infusions, by transmitting real-time data to a pump. Similar technology has been developed by Google, although their lens is not (currently) fully transparent, and Noviosense, which requires a…

Non-invasive tear sensor continuously monitors glucose
Noviosense is a flexible sensor glucose monitor, worn in a lower eyelid. The wireless, battery-free wearable tracks glucose levels in tears, and continuously sends measurements to one’s phone. One of three electrodes is coated with an immobilized enzyme, which converts glucose into gluconic acid, leaving the co-enzyme FAD reduced to FADH. An oxygen molecule oxidizes the…

Wearable + cloud analysis track Huntington’s disease progression
In the latest pharma/tech partnership, Teva and Intel are developing a wearable platform to track the progression of Huntington’s disease. There is no cure for the disease, which causes a breakdown of nerve cells in the brain, resulting in a decline in motor control, cognition and mental stability. The technology can be used to assess the effectiveness…

Gait sensors predict falls, allowing preventive intervention
University of Missouri’s Marjorie Skubic has used sensors to measure gait speed and stride length, to predict falls. The goals is to use wearables and smart home technology to preserve independence and allow seniors to age in place. Data was collected at an independent-living style retirement residence. Images and nurse alert emails were generated when…

Affective computing system responds to dementia patient emotions
SenseCare (Sensor Enabled Affective Computing for Enhancing Medical Care) is a Cork Institute of Technology led project meant to teach computers how to recognize and respond to human emotions. The goal is to use applied psychology to monitor and improve the care of dementia patients. The affective computing based system will manage data from voice and face…

NFC powered ultra-thin health monitoring patch
Powering wearables for efficient, long term, continuous, use remains a challenge. Illinois professor John Rogers has, again, disrupted himself. His new, stretchable, ultra-thin, health monitoring patches are wirelessly powered via smartphone near field communication. This enables the devices to be 5-10 times thinner than before — increasing comfort and therefore the willingness of people to wear…

GSK/Verily “biolectronic medicine” partnership for disease management
Galvani Biolectronics is a Verily/GSK company, created to accelerate the research, development and commercialization of bioelectronic medicines. The goal is to find solutions to manage chronic diseases, such as arthritis, diabetes, and asthma, using miniaturized electronics. Implanted devices would modify electrical signals that pass along nerves, including irregular impulses that occur in illness. Initial work will…

Implanted thread provides real-time diagnostic data
Tufts University researchers have created a thread-based diagnostic platform to provide real-time health data for implanted devices and wearables. Thread-integrated nano-scale sensors, electronics and microfluidics can be sutured through multiple layers of tissue . Measures of tissue health (pressure, stress, strain and temperature), pH and glucose levels are collected. Results are transmitted wirelessly. The system can be used…

Injectable sensor continuously monitors multiple body chemistries
Profusa injectable sensors are designed for the simultaneous, continuous monitoring of multiple body chemistries including metabolic and dehydration status, ion panels, blood gases, and other biomarkers. The company will initially provide real-time monitoring of soldier’s health, but its sensors can be used to manage peripheral artery disease, diabetes or COPD, or enhance sport performance. The small,…
