A device for measuring a biological signal, including a cardiovascular signal. The device includes a force sensor positioned to measures a biological signal as a varying force exerted on the device and/or electrical signal sensors that cooperate with each other to measure a biological signal as an electrical signal sensed from the user. The device includes a processor that receives the biological signal, determines, from the biological signal, one or more biological parameters, and generates output representative of the one or more biological parameters.
