Sensor detects swallowing problems in stroke patients

http://www.futurity.org/health-medicine/stick-on-sensor-detects-trouble-swallowing/  A small, external sensor developed at the University of Pittsburgh records how a person swallows and could result in more efficient and less invasive testing for stroke patients. Dysphagia can have dire consequences like malnutrition, dehydration, pneumonia, and even death. Current evaluation and monitoring methods are often cumbersome and not as effective as they […]

Implantable chip analyzes blood and sends data to doctors

http://www.wired.co.uk/news/archive/2013-03/20/implantable-chip-doctor A multidisciplinary Swiss team has developed a tiny, implantable device that instantly analyses the blood before wirelessly sending the data to a doctor. The device can be used for monitoring general health, but the team also sees immediate applications in monitoring the efficacy of treatments such as chemotherapy in order to tailor drug delivery to a […]

Fujitsu facial imaging technology measures pulse

http://www.sys-con.com/node/2582171 A Fujitsu research lab has developed software that can accurately measure a subject’s pulse using the small digital cameras attached to smartphones and tablets. The technology is based on the fact that the brightness of an individual’s face changes slightly as their heart beats, due to their blood flow. Hemoglobin, which carries oxygen around […]

A move toward aggregating health data from various devices and apps

http://gigaom.com/2013/03/15/tictrac-emerges-to-help-make-health-tracking-more-mainstream/ It seems that every day a new app or device promising the ultimate in health or fitness monitoring enters the market.  A startup has created a personal analytics dashboard which gives people a big picture view of their own aggregated data and underlying patterns, helping them make sense of the numbers.

Ultra thin sensors printed on skin to monitor health

http://www.biometricupdate.com/201303/super-thin-wearable-sensor-monitors-health-transmits-data/ Eliminating the elastomer backing makes the device one-thirtieth as thick, and thus “more conformal to the kind of roughness that’s present naturally on the surface of the skin,” says John Rogers at the University of Illinois. It can be worn for up to two weeks and can measure temperature, strain, and the hydration state of […]

Researchers explain the goals of a new brain-mapping project

http://www.technologyreview.com/news/512141/the-brain-activity-map/ A proposed effort to map brain activity on a large scale, expected to be announced by the White House later this month, could help neuroscientists understand the origins of cognition, perception, and other phenomena. These brain activities haven’t been well understood to date, in part because they arise from the interaction of large sets […]

Computer modeling may help soldiers, athletes, avoid concussions

http://hub.jhu.edu/2013/03/07/concussion-research-impact Johns Hopkins engineers have developed a powerful new computer-based process that helps identify the dangerous conditions that lead to concussion-related brain injuries. Professor K.T. Ramesh led a team that used a technique called diffusion tensor imaging, together with a computer model of the head, to identify injured axons, which are tiny but important fibers that […]
