SYSTEMS AND METHODS FOR MONITORING REDUCED PRESSURE SUPPLIED BY A DISC PUMP SYSTEM

摘要

A disc pump system includes a pump body having a substantially cylindrical shape defining a cavity for containing a fluid, the cavity being formed by a side wall closed at both ends by substantially circular end walls, at least one of the end walls being a driven end wall. The system includes an actuator operatively associated with the driven end wall to cause an oscillatory motion of the driven end wall and an isolator is operatively associated with the peripheral portion of the driven end wall to reduce dampening of the displacement oscillations. The isolator comprises a flexible printed circuit material that includes a strain gauge. The strain gauge measures data that may be used to determine the amount of pressure provided by the pump.
