An electrical resistive heating system having a Nitinol heater element in the form of wire, rod strip or tube, is flexible, ductile, tough aid chemically non-reactive. The element has connectors at each end for leads from a controller that controls the flow of current through the heater element from a source of electrical power. The Nitinol heater element is treated to have an electrically insulating surface that is also hard and chemically non-reactive, so the heater element can be put in intimate contact with the materials or substrate to be heated without shorting or electrical shock to people or equipment. The controller uses temperature data feedback from a separate temperature sensor such as a thermocouple, or uses the resistance of heater element itself as a temperature sensor, since the resistance of the Nitinol changes with temperature in a predictable way.

1. An electrical resistance heater element for heating a material or substrate in intimate contact with said heater element, comprising:a Nitinol ribbon having electrical contacts at opposite ends of said element for connection to an electrical circuit producing a flow of current to said Nitinol ribbon for heating of said material or substrate, and having an integral electrically insulating surface for preventing electrical shorting of said element by said substrate or material, and for preventing electrical shocks to people in contact with said element.
