The apparatus comprises an antenna (3, 4) for sending and/or receiving electromagnetic waves to and/or from the object (2) for measuring a property of the object, wherein the antenna (3, 4) comprises an electrically conductive element for functioning as an electrode for measuring a further property of the object.
Abstract:
A measuring device for attaching to the human body includes a number of ECG electrodes (14,16) supported on a deformable bridge (18) with a strain sensor (20). The unit can be attached to the upper body of a patient, for example with one electrode (14) on the sternum and the other (16) on the abdomen, and the strain sensor used to measure respiration using the electrodes as purely mechanical couplings whilst the electrodes are used at the same time to measure the electrical excitation of the heart, which is the ECG.
Abstract:
The invention relates to the detection of electrical and mechanical cardio- vascular activities of a patient, especially to early decompensation detection of congestive heart failure patients (CHF). The device according to the invention comprises a transmitter for transmitting electromagnetic signals of a predefined frequency into the chest of the patient, a Doppler radar sensor 1 for detecting a Doppler radar signal reflected in the patient's chest, and an ECG unit 3 for capturing an ECG signal of the patient's heart. This device allows for simultaneous detection of electrical and mechanical cardio -vascular activities of a patient which can be used in an easy and reliable way and which allow for implementation in a hand-held or wearable device.
Abstract:
A method comprising the step of using a plurality of doppler radars disposed on the seat belt or integrated into the seat belt for monitoring vital body signs of a person seated in a seat of a motor vehicle is disclosed. The disclosed method unobtrusively monitors vital body signs like heart rate and respiration of the person seated in the motor vehicle. A number of safety applications as well as wellness applications can be enabled. Examples are detection of momentary sleep of the driver, vital sign monitoring in case of an accident as well as relaxation exercise using biofeedback to reduce stress for drivers.
