The feature looks so bright
A study at Northwestern University and the University of Illinois at Urbana-Champaign device that can alert people if they have difficulties in cardiovascular or simply alert them time to put some skin moisturizers.
Use wireless technology of thousands of very small liquid crystals on a flexible substrate to sense heat.
When the device turns into a special color, then he will know the person who wears that there is something unnatural.
“The device is not visible, a very small mechanically similar to dramatically whipped himself and comfortable, and has a volume of about five square centimeters, it can be placed directly on the skin and wear it permanently health surveillance around the clock. The research team has tested the device on my wrist some people.
One can imagine the cosmetic companies interested are able to measure the dryness of the skin in a way the mobile device and a way that is extraneous. Zhang Yi says the first author of the study and assistant professor in civil and environmental engineering research in the northwestern region that the device is a very practical and effective, when the skin stretched and pressed or twisted, stretched device is also compatible.
Add to that this technology will be used changes in temperature known to the skin’s surface to determine the blood flow rate, which is always directly related to cardiovascular health, and levels of moisturizing the skin. (When it is dry skin, thermal conductivity) change. The device consists of a set of liquid crystals up to 3600, for every half-millimeter square, placed on a thin substrate, soft and expansive. When the crystal senses temperature, it changes color.
