1. An apparatus, comprising:
- a substrate;
a first flexible electronic part located on the substrate, wherein the first flexible electronic part comprises a substantially strain resistant conduit having a first carbon content; and
a second flexible electronic part located on the substrate,wherein the second flexible electronic part comprises a strain sensitive sensor having a second carbon content greater than the first carbon content, wherein the substantially strain resistant conduit and the strain sensitive sensor both comprise a metal and carbon matrix.

19. A method to form a strain sensitive sensor, the method comprising:
-
depositing a plurality of metal traces substantially parallel to one another on a substrate, wherein the traces include palladium; curing the plurality of metal traces for a specified time and temperature to form a palladium and carbon matrix, wherein the cured metal traces have a gauge factor from about three-hundred to about four-hundred in response to strain; and depositing a first electrode in contact with one end of the plurality of metal traces and a second electrode in contact with an opposite end of the plurality of metal traces. - View Dependent Claims (20, 21, 22)

23. A method to form a strain resistant conduit, the method comprising:
-
depositing a metal trace on a substrate, wherein the metal trace includes palladium; and curing the metal trace for a specified time and temperature to form a palladium and carbon matrix, wherein the specified time and temperature comprise a time of about thirty minutes at a temperature of about two hundred thirty degrees Celsius and are effective to cause the cured metal trace to exhibit a zero-to-near-zero gauge factor in response to strain over a radius.
