Abstract: A blood flow disorder detection device includes: a sensor sheet including a flexible substrate and a plurality of sensors provided on the flexible substrate; and an analyzer that analyzes outputs of the plurality of sensors. The plurality of sensors measure different types of blood flow information of a living tissue, the blood flow information being obtained by attaching the sensor sheet to the living tissue. The analyzer detects a blood flow disorder in the living tissue by analyzing the different types of blood flow information from the plurality of sensors.

Abstract: Three organic compounds mixtures of liquid-crystal properties, which when mixed together in a precisely determined weight ratio, may show an ability to form thermo-optically active mesophases of established, narrow range thermooptical transitions separation, every 0.5° C., in the temperature range: from 31.8° C. to 32.8° C., from 32.8° C. to 33.8° C., and from 33.8° C. to 34.8° C. and system including these mixtures. The use of these mixtures and the system containing the above mentioned mixtures for colorimetric detection of temperature differentiation on the surface of biological objects in a narrow range of temperatures.
