“Each year, about 80,000 people in Germany become seriously ill from occlusions of veins caused by blood clots. Such thromboses can cause pulmonary embolism or even heart attacks. Even airline passengers at long distance flights can be affected by deep vein thrombosis. But with the new system, a fast and easy test of a risk of travel-related thrombosis will soon be possible.
The sensory wristband is a combination of polymer and conventional electronics. Lighting elements, sensors and polymer resistances printed on the foils are connected into one system with integrated circuits made of silicon. A three micrometer-thin resonance circuit with an etched coil — a kind of minute antenna — records the electric smog. An interdigital capacitor attached to a foil and only 30 micrometers thick detects skin moisture. Comb-shaped, narrowly interlaced meanders made of copper bands of a mere 0.5 micrometer thickness, measure the body temperature.” More HERE.
