How to measure temperature with ADPD410x

Hello,

I'm a master student in biomedical engineering and I'm developping a miniature sensor for PPG, ECG and body temperature. For this I'm using the ADPD4101. I'm in the very first step of the project: the 2D schematics.

I have seen in the datasheet of the evaluation board how to connect everything for ECG and PPG measurements but not for T measurement, and I can't find the information. Should we use an external temperature sensor? Or is there any temperature sensor inside of the ADPD410x?

It's the first time I'm asking questions here, and I hope my question is not too simple but I'm a bit lost concerning the temperature measurement.

Thanks for the help.

Regards, 
FYON Arthur.
