Giga-tronics (San Ramon, CA) offers the GT-8555A 100 MHz to 20 GHz USB Peak Power Sensor, which provides fully calibrated peak and average power measurements, with a high dynamic range and PC-based user interface. The power sensor delivers 20 GHz frequency range, 2,000 readings per second typical, dynamic range of –40 to 20 dBm...

Since it was established 11 years ago, the Stanford Biodesign Innovation Program has led to more than 200 patents and 24 start-up companies, including Spiracur, the company behind the SNaP Wound Care System (featured in the January issue of Medical Design Briefs). This intensive one-year program helps...

If a prosthesis is not fit or aligned correctly, it can affect a patient's walking patterns, resulting in an asymmetric gait. These abnormal gait patterns can increase the stress on the healthy limb, leading to problems later in life such as arthritis. Researchers at Oak Ridge National...

Researchers have made T-rays into a much stronger directional beam than was previously thought possible — and have done so at room-temperature conditions. This is a breakthrough that should allow future T-ray systems to be smaller, more portable, easier to operate, and much cheaper than...

The process of monitoring blood glucose levels through finger pricking is an inconvenience at best for the estimated 26 million diabetics in the U.S. It's no mystery why researchers have continued to set their sights on developing more convenient and less invasive methods of monitoring glucose...

From delivering care to the developing world, to remote echocardiography, to hearing assessment, telemedicine has opened doors to new and potentially improved forms of diagnosis and treatment. Dermatology is one area in particular that stands to benefit greatly from this technology.

Raven II, a robotic surgery system developed at UC Santa Cruz and the University of Washington, is being shared on an open-source basis with five other universities. Researchers hope that this will enable users to share software, replicate experiments, and collaborate in other ways — and ultimately...

A Microsoft Research Connections project proposes to develop a contact lens that monitors blood glucose levels for type 1 diabetes patients. Other non-invasive alternatives to the finger-pricking method have also been explored elsewhere — such as this tear-based glucose sensor from Arizona State University,...

The road to better, longer-lasting hip implants may be paved with better lubricants. A team of engineers and physicians recently discovered that graphitic carbon is a key element in a lubricating layer for longer-lasting metal-on-metal hip implants. The ability to extend the life of implants would have enormous...

Engineers at the University of Illinois have developed a bandage that stimulates and directs blood vessel growth on the surface of a wound. The bandage, called a “microvascular stamp,” contains living cells that deliver growth factors to damaged tissues in a defined pattern. The new approach is the...
