Dear Chandan N,
As previously answered in your case. MPL3115A2 is not part of our medical certificated pressure sensors, so, there is no Bio-Compatibility information for this device. For your application, I rather recommend you to use the FXPQ3115BV which is designed for medical applications. The MEMS and ASIC die are coated with a biomedically-approved gel. The gel is a nontoxic, nonallergenic elastomer which meets all United States Pharmacopeia (USP) biological testing class VI requirements.
Datasheet for the FXPQ3115BV: https://www.nxp.com/docs/en/data-sheet/FXPQ3115BVSDS.pdf
The material composition declaration for this device can be found in the following link: https://www.nxp.com/mcds/FXPQ3115BV.pdf
I’m afraid that the full product specification for the FXPQ3115 is marked as a confidential document, so it cannot be shared without a signed NDA with your NXP sales representative or Distributor.
This device is still under pre-production, I recommend you to contact your local distributor for more details regarding availability for this device.

Have a great day,
