Abstract:

A new apparatus that can measure the blood pressure of astronauts /without encumbering
their movements is uses a novel bilateral piezoelectric array/microprocessor system
(PAAPMS) which measures the blood pressure at the superficial temporal artery.  Blood
flow computer based modeling of circulation from the heart to the temple has provided
the data which verifies the viability of this new apparatus.  The use of a multi-sensor
array provides both noise cancellation and simplifies the signal processing circuitry
necessary for display on a spacecraft microcomputer or for ground-based telemetry
monitoring.
