Abstract
An improved skin blood flow measurement apparatus consists of a chassis with an antenna connected with the chassis such that the antenna directs RF energy at an area of a skin surface below the chassis. A temperature sensor is also connected with the chassis such that the temperature sensor is held in fixed relation to the antenna and such that the temperature sensor is also directed to the same said area of a skin surface below the chassis for measurement of temperature of the area and further where the temperature sensor does not contact the skin surface and where the chassis supports the antenna and the temperature sensor in fixed relation to the area.
