|Title:||PRESSURE SENSING ELEMENT AND SAFETY APPARATUS INCLUDING SAME|
The present invention relates to a pressure sensing element having an expanded pressure sensing section and a safety apparatus including the same. A pressure sensing element, according to an embodiment of the present invention, comprises: an intermediate layer having a structure in which at least two functional layers are stacked on each other; a first electrode layer disposed on one surface of the intermediate layer and including a plurality of first electrode patterns; and a second electrode layer disposed on an opposite surface of the intermediate layer to overlap the first electrode layer with the intermediate layer between the first and second electrode layers, wherein among the two functional layers, the first functional layer has a thickness linearly varying in a first pressure section, and the second functional layer has a thickness linearly varying in a second pressure section; the maximum pressure in the first pressure section is lower than that in the second pressure section; and the minimum pressure in the second pressure section is included in the first pressure section.
