... and establishment of an experimental setup for calibration. Thin film sensors are prepared in-house by platinum ink mounted on an insulated substrate (Pyrex). Experiments are carried out by applying step heat load on the thin film sensor using laser light of known wattage. Recorded transient temperature data...

... at ten locations simultaneously. Analytical modeling was performed to estimate the sensor’s sensitivity and time response. Calibrations were performed in conduction and radiation yielding an average heat flux sensitivity of 20.4 μ V / ( kW / m 2 ) . Time response measurements were also performed, which...
