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, featured in MDB last June. According to Microsoft, this is representative of a trend toward Natural User Interface (NUI) technologies — technologies that aim to provide benefits to users without being intrusive. A new device on the market, the YumaLite, also appears to fit into this category.

Right now, signals from your brain are instructing the muscles around each eye to contract, panning your view left to right and adjusting focus along the way. The photoreceptors in your eyes react to the photons reflecting off each letter, ultimately transmitting information through the optic nerve, back to the primary visual cortex, where they are translated into meaning. Although it goes mostly unnoticed, your nervous system is constantly hard at work.

According to Pantec Biosolutions AG (Liechtenstein, Europe), the global aesthetic market, which includes skin rejuvenation, is expected to grow from a $4.4 billion market in 2010 to a $7.5 billion market in 2015. Meanwhile, the market for transdermal drug delivery is growing rapidly and is expected to be a multi-billion dollar market by 2015. Designed for medical professionals and consumers, these new devices offer a precise delivery method for a variety of medical applications, such as skin rejuvenation, in-vitro fertilization, and vaccinations.

The concept of a "one size fits all" medical device sounds attractive in theory, but in practice, it isn't very likely that one device can be developed to meet every patient's unique needs. This is particularly true when it comes to pediatric devices, which may not receive as much attention or funding as devices that were developed with an adult demographic in mind. In comparison to adults, children exhibit not just differences in body size, but also different immune response reactions.

Last June, Analog Devices wrote an article in Medical Design Briefs about the increasing need to engineer devices that provide healthcare in the home. A recent article in the Wall Street Journal highlights one technology that fits into this trend: a small purse-sized device, developed by Awak Technologies of Singapore, that would provide dialysis patients with the option to conduct treatment from home.

With funding from a space medicine research institute, a breakthrough device could someday kill tumors and stop internal bleeding without knives, scalpels, or stitches — basically without surgery as we know it.
