Thermometer as thin as a human hair

The human body's temperature gauge is incredible, because it has a thick thin as a human hair, it's cheap, and able to measure the body temperature to 0.02 degrees Celsius. "This thermometer is inexpensive and simple, can be affixed to the skin like a kid's temporary tattoo sheets," said John Rogers, a researcher from University of Illinois, who co-developed the thermometer technology. Level of accuracy, Rogers said, could match the infrared camera that costs U.S. $ 250 thousand.

The scientist have developed wearable, flexible thermometers only 50 microns wide, or about half the width of the average human hair. This thermometer has a measuring holograms with different colors, which shows the human body temperature. Sensor in it is made of gold or silicon membrane fibers were mounted on a thin sheet of rubber. Rubber sheet with holes deliberately keep skin can "breathe". The thermometer can also be used to gather important data such as blood flow and cardiovascular health describes the condition of the skin.

The thermometer can also work as a small heater. Thin sheets that can adjust the temperature of the skin as a therapy which helps the absorption of the drug into the blood or help the body absorb the nutrients needed during the process of wound healing. Researchers are placing electrodes in the thin sheet sensor to read the incoming data. They plan to develop thermometer can transmit wireless data.

And now the latest thermometers are often used in hospitals, including sensor thermometer paste, is relatively cheap and flexible. Patients are free to move during use. However, it can not provide the detailed temperature changes and cause irritation. Meanwhile, the infrared camera can give you the body temperature with high accuracy. Indeed, the tools are expensive and patients have to dwell for a moment. *** [EKA | FROM VARIOUS SOURCES | LIVESCIENCE | GABRIEL TITIYOGA | KORAN TEMPO 4348]
