“…Besides, low‐pressure sensor is also an important component for mechanical ventilator [17] an important device for providing assisted respiration, tonometer for the measurement of intraocular eye pressure [18], and so on. Its applications further expand in engineering and space explorations, such as HVAC [19], and International Space Station [20] environmental control of modem aircrafts [21]. A variety of miniature level pressure sensors have already been developed, examples include electrofluidic [22, 23], optofluidic [24, 25], optical [26, 27], elastic membrane‐based [28–33], fluid interface [4, 34], colorimetric [35–39], optical fiber [40], and micro electromechanical system (MEMS) [41] sensors.…”
