  The morphology and velocity of the pulse wave in the arteries provide
meaningful information about the cardiovascular system. Nowadays, the pulse
wave is usually acquired using common blood pressure cuffs at the extremities.
This work describes a new measurement device which detects changes in
bioimpedance due to the pulse wave. The system is able to measure up to 1000
bioimpedances per second with a resolution of 24 bits. For comparison purposes,
an additional synchronized photoplethysmography circuit is implemented. Initial
measurements proved that the system is able to acquire the pulse wave at the
forearm.
