Medical Devices Optoelectronic Sensors in Medical Applications

Electronic components have been incorporated into medical equipment designs for years. Until recently, medical electronics has been focused primarily on the institutional side of the medical market, in expensive diagnostic equipment, such as MRI and CAT scanning machinery for use in hospitals and clinics. An aging and expanding population is accelerating the development of new and different medical equipment. Professionals in health-care settings want real-time, reliable, and accurate diagnostic results provided by devices that can go to the patient, whether he or she is in a hospital or clinic or at home, being monitored remotely. The equipment should be appropriate for both home care and ambulatory treatment; it must be patient friendly, both technically and physically; and it must be small, light, and energy efficient. read more...

Automotive industry driving optoelectronics

Car ownership is increasing in emerging markets as cars become more technologically advanced in others. Infrared components and LEDs are playing an increasingly prominent role in this sector. Infrared components, such as light sensors, can be used to detect ambient light to determine when everyone ought to switch on or off headlamps. These types of sensors can also be used to determine whether rain is on the windshield or whether to turn on or off the windscreen wipers. There are also new emerging applications for these kind of infrared components as well. Such as gestured control for the infotainment console in the center of the car. And also there's another application such as night vision to determine whether there's objects or sharp bends in the road. read more...

Nanostructured metal coatings let the light through for electrical devices

CHAMPAIGN, Ill. – Light and electricity dance a complicated tango in devices like LEDs, solar cells and sensors. A new anti-reflection coating developed by engineers at the University of Illinois at Urbana Champaign, in collaboration with researchers at the University of Massachusetts at Lowell, lets light through without hampering the flow of electricity, a step that could increase efficiency in such devices. read more...

Nanocavity Paves Way for Thinner Solar Panels, Optoelectronic Devices

Researchers have been looking for ways to improve energy absorption and transfer to improve photovoltaics and optoelectronics. We told you recently how scientists invented new energy-carrying particles to this end, and now researchers at the University of Buffalo (UB) are experimenting with nanotechnology to improve the design of ultrathin solar panels, video cameras, and other optoelectronic devices. read more...
