An overview of 8 new sensor based health tracking devices. Some predict that 400 million such products will enter the market by 2014.
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 patient’s unique needs.
The Health eHeart Study will use smartphone apps, sensors and other devices to gather data on a wide variety of measures associated with cardiovascular health—including blood pressure, physical activity, diet and sleep habits—in real time.
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 the body, absorbs green light, so analyzing the change in color of parts of the face reveals their heart rate.
As most image sensors capture pixel information in red, blue and green, they have the ability to detect hemoglobin built in. Fujitsu’s technology keeps track of specific regions of the face over time to take pulse measurements.
Redundancy is arriving to commercial electrical circuits. A circuit, reminiscent of neural computation, enables backup circuitry to be engaged when main functioning breaks.
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.
Sensor technology will enable smartphone users to keep track of sleep patterns, heart rate, exercise, and weight.
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 the skin, and also be used to monitor wound healing.
The National Football League and GE announced a $60 million effort to speed up research into brain injuries and the development of new technologies to help protect the brain from traumatic injury to benefit athletes, the military and the broader public.
The initiative includes a $40 million research program into imaging technologies to improve diagnoses and an additional $20 million pool of funds open to researchers and businesses trying to improve the prevention, identification and management of brain injuries.
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 of neurons whose coordinated efforts scientists cannot currently track.
An article published Thursday in Science online expands the project’s already ambitious goals beyond just recording the activity of all individual neurons in a brain circuit simultaneously. Researchers should also find ways to manipulate the neurons within those circuits and understand circuit function through new methods of data analysis and modeling.
