A heteropolytungstate based 2D layered porous framework with high proton conductivity A heteropolytungstate cluster [{Ru2O(bpy)2}2{Bi2W32O110}]10− (bpy = C10H8N2) was incorporated into a 2:1 type layered porous framework by interweaving the Na+ bridged cluster chains through the hydrogen bonding ability of bpy ligands. It features multiple pore channels rich in hydrogen-bond network, contributing the high conductivities > 10–2 S cm–1 at 298–358 K and 85% RH.

4. Experiment and DiscussionThe performance experiment of resonant pressure sensors in this paper mainly focuses on their static performance indicators, including sensitivity, fitting error, hysteresis error, and repeatability error. The environmental conditions for the performance experiment are standard atmospheric pressure, room temperature environment, relative humidity below 85%, and no external interference such as vibration, impact, or acceleration.
