Microneedle sensors may allow real-time monitoring of body chemistry (12/14/2011)

Researchers from North Carolina State University, Sandia National Laboratories, and the University of California, San Diego, have developed new technology that uses microneedles to allow doctors to detect real-time chemical changes in the body -- and to continuously do so for an extended period of time. ...> Full Article

Controlling robotic arms is child's play (5/18/2011)

Move your arm and the robot imitates your movement. This type of intuitive handling is now possible thanks to a new input device that will simplify the control of industrial robots in the future. But that is not all: The sensor system can also help regulate the movements of active prostheses. The new technology will be presented at the Sensor+Test trade fair from June 7-9 in Nuremberg. ...> Full Article

A 'check engine' light for the human body? (3/20/2011)

Imagine a sensor implanted in your body that signals when you're getting sick -- almost like the "check engine" light in a car. That scenario sounds like pure fantasy, but it may be closer to reality than many people think, according to an article in the current edition of Chemical & Engineering News, ACS' weekly newsmagazine. ...> Full Article

New artificial skin could make prosthetic limbs and robots more sensitive (9/16/2010)

Stanford researchers have developed an ultrasensitive, highly flexible, electronic sensor that can feel a touch as light as an alighting fly. Manufactured in large sheets, the sensors could be used in artificial electronic skin for prosthetic limbs, robots, touch-screen displays, automobile safety and a range of medical applications. ...> Full Article

DNA puts Stanford chemists on scent of better artificial nose (8/24/2010)

Stanford chemists working on an "artificial nose" have developed new sensors that offer more information "per sniff" than most existing noses. The sensors, made by sticking fluorescent compounds onto a backbone of DNA, are easy and cheap to make and could help the devices become widely available. ...> Full Article

Implanted glucose sensor works for more than 1 year (7/30/2010)

Bioengineers at the University of California, San Diego and GlySens Incorporated have developed an implantable glucose sensor and wireless telemetry system that continuously monitors tissue glucose and transmits the information to an external receiver. The paper, published in the July 28, 2010 issue of the journal Science Translational Medicine, describes the use of this glucose-sensing device as an implant in animals for over one year. After human clinical trials and FDA approval, the device may be useful to people with diabetes as an alternative to finger sticking and short-term, needle-like glucose sensors that have to be replaced every three to seven days. ...> Full Article

Women clear winners with heart failure device (5/18/2010)

For women with mild heart failure, device therapy is an extremely attractive option to prevent progression of the disease. A new study found that women with mild heart disease who had a cardiac resynchronization device combined with a defibrillator (CRT-D) implanted had a 70 percent reduction in heart failure alone and a 72 percent reduction in death from any cause. This is the first study in which a heart failure therapy has proven more effective in women than in men. ...> Full Article

Vital functions monitored with wearable and implantable devices (5/11/2010)

Physiological signals can nowadays be easily monitored with measurement devices implanted inside a living body. Researcher Jarno Riistama from Tampere University of Technology believes that the next tech-savvy generation represents a potential customer base for new applications in the field. They might be interested in monitoring their personal health with implantable electrocardiogram devices. The device could also be used as a diagnostic tool in emergencies, because it gives medical personnel instant access to the patient's EKG data. ...> Full Article

Energy-autonomous sensors for aircraft (10/7/2009)

Aircraft maintenance will be easier in future, with sensors monitoring the aircraft skin. If they discover any dents or cracks they will send a radio message to a monitoring unit. The energy needed for this will be obtained from temperature difference. ...> Full Article

Color sensors for better vision (10/6/2009)

CMOS image sensors in special cameras -- as used for driver assistance systems -- mostly only provide monochrome images and have a limited sensitivity to light. Thanks to a new production process these sensors can now distinguish color and are much more sensitive to light. ...> Full Article
