The last few years have seen the development of larger, higher power, higher luminescence light-emitting diode (LED) chips. Prior to this, LEDs were typically 0.020" x 0.020", came in various colors and were used primarily as optical indicators. This new breed of LEDs come in various colors, including white and UV, are typically 0.040" x 0.040" and are designed to provide high intensity light for illumination applications. Individually packaged versions of these LEDs are being used in arrays and clusters to replace standard incandescent and compact fluorescent light bulbs and are much more efficient at converting electrical power into usable optical power.

The need to minimize healthcare costs is creating greater demand for medical electronics equipment that, among other things, improves and expands patient diagnostics inside and outside healthcare facilities. For example, portable medical instruments such as glucose meters, blood pressure monitors, and oxygen meters can be designed with communication capabilities to provide continuous information to caregivers almost anywhere. Small handheld devices can also improve various diagnostic procedures in medical offices. While such devices hold the promise of improved care at lower cost, they require advanced technologies that allow greater miniaturization to improve portability and functionality while providing safe usage.
New Process for Flexible Electronics
Posted in News, Electronics, Sensors on Monday, 17 September 2012
An associate professor of electrical and computer engineering at Wayne State University, Detroit, MI, has developed a silicon-on-insulator (SOI)–complementary-metal-oxide-semiconductor (CMOS) process for fabricating flexible electronics. As reported in Applied Physics Letters, the technology may some day be used in a range of wearable health monitoring devices and medical implants, such as retinal prostheses, balloon catheters, and stents.

Vanderbilt University researches have developed a way to combine Photosystem 1 (PS1), the photosynthetic protein that converts light into electrochemical energy in spinach with silicon (the material used in solar cells), in a fashion that produces substantially more electrical current than has been reported by previous biohybrid solar cells.
Getting to the Heart of Tomorrow's Cardiovascular Technologies
Posted in Features, Electronics, Power Management, Power Supplies on Wednesday, 01 August 2012
Cardiovascular disease is the number one cause of death in the world. About 1.2 million Americans suffer from heart attacks every year. Approximately 2,000 Americans get heart transplants each year, but transplant hearts are in short supply, and many thousands of other advanced heart failure patients are left on the waiting list.
Seven Advantages of Membrane Switches for Medical Electronics
Posted in Features, Electronics, Displays/Monitors/HMIs, Drug Delivery & Fluid Handling, Patient Monitoring on Sunday, 01 July 2012
With the large number of user interface options available today, it is easy to forget why the membrane switch is an excellent choice for medical instrumentation. The basic advantages are still the same as they were two decades ago, when membrane switches became the interface of choice for a multitude of products, including toys and games, high-end appliances, industrial controllers, and automotive controls. These advantages have been enhanced by developments in materials, processes, and design expertise.
