1. A thermocouple device comprising:

  • a medical device comprising a polymer substrate formed of poly(vinyl chloride) comprising a substantially tubular portion;

    a first thermocouple element printed directly on the substantially tubular portion with no substrate between the first thermocouple element and the substantially tubular portion, the first thermocouple element comprising a first metal containing ink composition comprising a polymeric binder and metallic particles; and

    a second printed thermocouple element in electrical contact with the first printed thermocouple element making a thermocouple junction, the second printed thermocouple element comprising a second metal containing ink composition comprising a polymeric binder and metallic particles with a Seebeck coefficient sufficiently different from the first metal containing ink composition for the first and second printed thermocouple elements to together produce a thermocouple effect, wherein the polymeric binders of the first and second ink compositions independently comprise poly(vinyl chloride) and are entangled with the substrate.
