Among Curts’ more unique problem solutions are those having to do with devices intended for  implantation in the human body. Depending on the materials from which they are fabricated, the possibility of toxic reactions can occur in such cases,  deposition of a non-toxic coating has eliminated the problem. Another unique problem was the creation of a pressure transducer using concentric glass tubes. The inside surface of the outer tube  and the outside surface of the inner tube were metallized to form an air dielectric capacitance transducer.
