    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: 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.
