Hi there! I am working in a research group and was wondering if you could provide the structural design and type material used for the sensing element of HTS 221 sensor. Thanks!

Hi @JLiew.1162 ,

As reported in the datasheet, p.1:

The sensing element consists of a polymer dielectric planar capacitor structure capable of detecting relative humidity variations and is manufactured using a dedicated ST process.

Unfortunately, we cannot publicly disclose further information.

Anyway, you might try to get more details by contacting a sales and representatives office from your region, by the online LINK..
