Development of Miniature Capacitance Pressure Transducers.

摘要

Techniques were developed to simplify the manufacture of ultra-miniature capacitive pressure transducers for physiological measurements. The transducers are of two types. The first is .046inches in diameter, (1.17mm),and is mounted at the tip of a four-foot catheter cable. An airway inside the catheter allows the direct measurement of relative pressures. Significant advances were made on all parts of the system over the state-of-the-art at the onset of the contract. (Author)
