Abstract
Flexible measurement probes are described for the determination of oxygen partial pressure; temperature and perfusion; and combined measurement of oxygen partial pressure, temperature, and perfusion. The probes are fabricated by patterning a metal coated substrate to form a conductive pattern of ribbon leads, insulating the conductive ribbon leads except for contact openings, and then attaching sensors to the conductive ribbon leads through noble metal plated open contacts. The plated contacts may be used directly to measure oxygen partial pressure.
