Mondal Shuvra

Provided is a button device including a humidity sensor. The button device includes a substrate having a plurality of sensing regions, a housing on the substrate, the housing separating a first sensing region of the plurality of sensing regions from other sensing regions, a porous structure within the housing, the porous structure having through-holes, a first electrode on the porous structure, a second electrode on the porous structure, the second electrode being electrically connected to the first electrode through the porous structure, and a temperature sensor disposed adjacent to the first sensing region to sense a temperature of the first sensing region, The porous structure includes a body having an outer surface defining the through-holes, the body having an air gap therein.

Humidity sensor and button device including the same

Provided is a temperature-pressure complex sensor with an anti-radiation property including a first sensing material which is a porous conductive film, and second sensing materials which are dispersedly disposed on a surface of the first sensing material. The second sensing materials may include a conductive structure having a two-dimensional crystal structure, and nanoparticles having a radiation shielding property which are disposed between crystal layers of the conductive structure.
