United States developed the "smart underwears" can monitor soldiers vital signs

United States researchers developed a new chemical sensors, and direct printing during the underwear elastic belt, even if the press, expand sensor electrodes, will not affect the ability of its induction.

Researchers said that the sensor can render the battlefield, widely used in wearable devices, in addition to monitoring the soldier's life signs, but also to assist in healing.

"Smart underwears" intelligence "of the main problems that were printing sensor can embed calculation based on the logic of a computer system for the monitoring of sweat and tears in the detection of lactate, oxygen, norepinephrine, glucose and other biological markers, and thus the degree of automatic diagnosis of soldiers, patient health status changes, etc., according to the diagnosis, the computer system to automatically release the quantitative drug, rescue personnel prior to implementation of the treatment.

The study leader, University of California at San Diego branch of nano-Engineering Department of Professor Joseph · Wang, select General underwear elastic tape is because its contact with human skin, so most closely can directly monitor the sweat.

A series of test laboratory confirmed, bending, stretching and massage directly printing in underwear elastic belt on the sensor, for the detection of hydrogen peroxide and NICOTINAMIDE adenine dinucleotide (NADH) capacity almost nothing harmful effects. In addition, you can target specific textile base select different ink color and Ink viscosity to optimize transducer performance.

In 2008, the nano research group acquired the United States field hospital online detection of significant funding. chip

At that time, researchers on the project's explanation is: lactate, oxygen, norepinephrine, glucose, etc. can be used as a biomarker of pain, suffering, they are biological input signal. Contains many enzyme electrode will act as a sensor, the biological markers into electrode another enzyme to be able to identify the product for the next logical operation. Electrode will assume the role of a converter produces a series of 0 and 1, 0 and 1 that reveals the pain and activate smart materials, release the drug.

For example, if a wounded soldier will enter a State of shock, electrode enzymes will feel lactate, dextrose and norepinephrine, biological markers of concentration will increase.

On the contrary, the enzyme produces product concentration changes: for example, hydrogen peroxide, NADH concentrations varying high; NAD + (cellular energy metabolism of Coenzyme necessary) of concentration will be lower, this will let the built-in logic structure of output signal "1, 0, 1, 0, ' these signals indicate that soldiers would shock, the system then trigger predetermined treatment response.

Researchers in the latest issue of the journal of the analysts pointed out that this new sensor successfully indicates that the electrode can be "part of the intelligent underwear", and this device will be able to apply to the United States Naval Institute is developed by "field hospital-chip" system (the system is mainly used for monitoring the status of the injured soldiers and provide drug treatment).
