Lateral pressure was applied to the elastomer, altering its contact angle and perturbing the grating's optical transmission spectrum.

Fourier analysis was employed to extract data from the optical transmission spectrum.

The sensor's response was tested under varying pressure and temperature conditions.

Main Results:

The sensor demonstrated monotonic pressure response from 0 to 50 kPa, with linear response from 0 to 15 kPa.
A low standard deviation of 0.25 kPa and maximum error of 0.5 kPa were achieved.
The sensor exhibited temperature independence, with a maximum error of 2% across a temperature range of 25°C to 75°C.
The sensor's performance was tunable by altering elastomer properties or pressure application orientation.

Conclusions:

The presented fiber optic pressure sensing scheme offers a novel and effective method for accurate pressure measurement.
The sensor's temperature independence and tunable range make it suitable for diverse applications.
This technology holds promise for advancements in optical sensing and metrology.
