The Bio-patch, developed by researchers at KTH Royal Institute of Technology, measures bioelectrical signals through the skin, gathering data on different parts of the body depending on where it is placed.
“On the chest it provides electrocardiography (ECG), on the skull it measures brainwaves (EEG), and on the forearm it can measure muscle response to stimulation from the nervous system (EMG),” says KTH researcher Geng Yang. It also has a built-in sensor that constantly monitors body temperature.
Pass-thoughts are thoughts that a headset records through brainwaves. The computer learns what your individual brainwaves are like and then identifies you. Traditionally, these brainwaves, called electroencephalograms (EEGs), are collected through expensive and sometimes invasive devices, so the pass-thought growth has been severely stunted.
Berkeley’s John Chuang and his team conducted a series of experiments to determine whether a single, less expensive, non-invasive EEG channel provided high enough signal quality for accurate authentication. For authentication, the computer needs to be able to accurately and consistently distinguish your brainwave patterns from someone else’s.
By selecting customized tasks for each user and then customizing each user’s authentication thresholds, the team was able to reduce error rates to below 1%, comparable to the accuracy of more invasive multi-channel EEG signals.
Sample sizes in neurological research are often too small to draw general conclusions.
Marcus Munafo, from the University of Bristol, and his colleagues analyzed hundreds of neuroscience studies to determine their “statistical power”. If the researchers’ figures are accurate—and if the 12-month period they looked at is representative of neuroscience research in general—then the implications are alarming. Bluntly, much of the published neuroscientific research is likely to be reporting effects, correlations and “facts” that are simply not real. At the same time, real phenomena are going unnoticed.
Understanding the brain is the most important opportunity of our lifetime. It’s afflictions and treatments can no longer be based on hypothesis, trial and error. Let’s not miss it.
By placing a small sensor in the brain’s motor cortex, interfaces can pick up on electrical activity, and translate it into commands that control a robotic arm. Now scientists have gone a step further. Instead of a wired brain-arm link, they have now developed a wireless connection powerful enough to work at a distance of three feet.
“Clinical applications may include thought-controlled prostheses for severely neurologically impaired patients, wireless access to motorized wheelchairs or other assistive technologies, and diagnostic monitoring such as in epilepsy, where patients currently are tethered to the bedside during assessment,” says David Borton, at Brown University.
Lively is an in-home sensor network for connecting elderly loved ones to their families. The system combines a series of wireless sensors, a data-collection hub and biweekly printed mailers that serve as kind of an analog social network. The basic setup measures medication compliance, food and drink intake and general activity outside the home.
Lively is crowdfunding on Kickstarter, with a goal of $100,000.
Scientists studying longevity have begun using powerful genomic technologies, basic molecular research, and, most important, data on small, genetically isolated communities of people to gain increased insight into the maladies of old age and how they might be avoided.
AirStrip OB is a mobile patient monitoring solution for women in labor. The system, developed by San-Antonio-based AirStrip Technologies, captures vital patient waveform data, including fetal heart tracing and maternal contraction patterns, in “virtual real time” and sends it to a physician’s mobile device.
ReWalk is a commercial bionic walking assistance system, utilising powered leg attachments to enable paraplegics to stand upright, walk, and climb stairs. The system is powered by a backpack battery, and is controlled by a simple wrist-mounted remote which detects and enhances the user’s movements.
Using a proprietary patented shape discrimination hyperacuity (SDH) test, myVisionTrack enables patients to regularly assess their vision function. myVisionTrack stores test results, tracks disease progression and can automatically alert a healthcare provider if it suspects significant deterioration of visual function in the patient. Clinical studies demonstrate that myVisionTrack’s shape discrimination hyperacuity test has comparable or higher sensitivity and specificity compared to clinically available standard visual function tests for detecting advanced maculopathy from high-risk moderate maculopathy.
Hospital patients may no longer need to be hooked up to a tangle of wires, thanks to new technology developed by Fujitsu Ltd. The device enables cord-free monitoring through radio-wave transmission of electrocardiograms, blood pressure and other data from sensors attached to patients’ bodies.
A transmitter mounted on each sensor sends readings to a receiver adjacent to the bed, which will be connected to a dedicated monitor or personal computer. The data transmission utilizes the “medical body area network” (mBAN), a telecommunications standard for medical equipment. The radio waves only have a transmission range of 5 meters and do not interfere with pacemakers or other medical equipment, Fujitsu officials said.
