Abstract: A method and apparatus for determining a heart rate of a biological body are disclosed. In the method and apparatus, light having a first wavelength and light having a second wavelength are emitted at the biological body. The first wavelength is associated with a first absorption coefficient for blood components and the second wavelength is associated with a second absorption coefficient for the blood components that is less than the first absorption coefficient. A first reflected signal is captured as a result of the light having the first wavelength being reflected from the biological body and a second reflected signal is captured as a result of the light having the second wavelength being reflected from the biological body. A heart rate signal is obtained based on the first and second reflected signals. A heart rate of the biological body is determined based on the heart rate signal.

Abstract: The present disclosure is directed to a solid body for a biomedical device, wearable by a patient and configured to acquire one or more physiological parameters of the patient. The solid body includes a first rigid portion, a second rigid portion and a connection portion of flexible type which couples the first and the second rigid portions to each other; and a control circuitry accommodated inside the first and/or the second rigid portions. The connection portion is interposed between the first and the second rigid portions, is integral therewith and is deformable so as to allow a relative movement of the first and the second rigid portions. The first and the second rigid portions are physically couplable to a first and to a second ECG electrode to couple the solid body to the torso of the patient. When the rigid portions are coupled to the ECG electrodes, the control circuitry is electrically coupled to the ECG electrodes and is configured to acquire, through the ECG electrodes, respective electrical signals indicative of said one or more physiological parameters.

Abstract: A wearable sensing device includes a connector socket provided with contact pads connectable to sensing electrodes for sensing biological electrical signals. A supply module is provided with a battery, which is housed in a first casing configured for reversible coupling with the connector socket. A control module is housed in a second casing distinct from the first casing and configured for coupling with the supply module and with the connector socket. The control module is equipped with a processing unit configured to process biological electrical signals detectable through the contact pads. Mechanical-connection members couple the supply module to the connector socket. Electrical-connection members distinct from the mechanical-connection members are configured to connect the battery and the contact pads to the control module.
