Abstract
The paper presents the results regarding the application of the microwaves and ultrasounds technology for realizing new types of sensors for the detection of the cardio respiratory activity. In the present paper are presented the performances of the biosensors, the functional characteristics and is made a evaluation regarding the compatibility with the human body. Both types of biosensors allowed the detection of two types of breathing: the thoracic and the abdominal one. As a reference transducer we used a piesoresistive sensor as reference. A good correlation was established between the two transducers and reference sensor. The method used can detect without any contact with the patient the breathing rate and the apnea appearance. The two detectors use different work principles: one detects the speed of the anatomical structures, the other one the movement of the human body. There were identified signals made by the cardiac activity and respiratory signals.
