Re: sensors

Blood flow is typically monitored by ultrasonic doppler, ask your family doctor.

Heart rate is usualy sensed with an IR pulse oximeter (aka photoplethysmograph) or ECG/EKG.

Re: sensors

a simple pulse meter can be made with an led and photo diode fed into an opamp and clipped to the end of your finger. Very common on exercise cycles
