1. A method for manufacturing a strain sensor on a turbine component, the method comprising:
- providing a turbine component comprising an exterior surface;
depositing a ceramic material onto a portion of the exterior surface using a deposition apparatus; and
,ablating at least a portion of the ceramic material using a laser to form a strain sensor comprising at least two reference points, andfurther comprising depositing a visually contrasting material where the ceramic material was ablated, whereby the visually contrasting material visually highlights identification of the first and second reference points of the strain sensor by their locations.

9. A method comprising:
-
providing a turbine component comprising an exterior surface; depositing a ceramic material onto a portion of the exterior surface; ablating at least a portion of the ceramic material using a laser to form a strain sensor comprising at least two reference points; depositing a visually contrasting material where the ceramic material was ablated; monitoring the turbine component, the monitoring comprising; measuring a second distance between a first of the at least two reference points of the strain sensor and a second of the at least two reference points of the strain sensor at a second time internal; and
,comparing the second distance to a first distance between the first of the at least two reference points of the strain sensor and the second of the at least two reference points of the strain sensor from a first time interval; whereby the depositing a visually contrasting material where the ceramic material was ablated visually highlights identification of the first and second reference points of the strain sensor by their locations. - View Dependent Claims (10, 11, 12)

13. A turbine component comprising:
-
an exterior surface; and
,a strain sensor deposited on a portion of the exterior surface, the strain sensor comprising partially ablated ceramic material comprising at least two reference points; visually contrasting material at least partially provided where the ceramic material was ablated; wherein the at least two reference points are at least partially separated by the visually contrasting material; and wherein the visually contrasting material visually highlights identification of the first and second reference points of the strain sensor by their locations. - View Dependent Claims (14, 15, 16)
