“…To some extent, the larger the diameter of the valve hole, the better the output flow, but limited by the size of the PIP hard tube; The distance between the valve and the liquid level will not significantly affect the valve output. The results also showed that the new pips had a good flowrate output, 3.7–10 times higher than previous studies (Sathiya et al, 2015; Vasuki et al, 2013).…”

“…Inspired by this machine, a new piezoelectric inertial pump (PIP) has been developed, and the new PIPs have the potential to deliver fluids through small diameter holes. Previous studies only used the traditional spherical check valve for a preliminary study, and the output flowrate is only 12–45 ml/min (Sathiya et al, 2015; Vasuki et al, 2013). It is necessary to make further research on this new type of piezoelectric inertial pump.…”

Sampling fluids from the small-diameter deep pipeline is a challenging problem. In this paper, a very simple, piezoelectric-actuated inertial pump (PIP) is developed using a bionic valve to solve these problems. The PIP consists of simple components, including a cantilever beam piezoelectric actuator, a hard tube, and a bionic valve made of silicone. The fluid is driven by the inertial force generated in the vibration process of the tube. A new bionic valve inspired by a heart valve has been designed which has the advantages of small flow resistance and large flow area. The authors described the working principle of PIP in detail, established the flow characteristics model of the bionic valve, and used COMSOL Multiphysics to analyze the characteristics of the bionic valve. By comparing the response characteristics of the bionic valve with different tilt angles, the optimal Angle was obtained. Finally, the experimental and simulation results were compared, and the basic performance of PIP was tested. The experimental results showed that: When the tilting angle was 45° and the valve hole diameter was 6 mm, when the voltage was 98 V and the frequency was 24.5 Hz, the maximum output flow of the piezoelectric pump was 170.25 ml/min.

“…A 2-DOF resonant sensor for mass and pressure measurement is investigated in [24]. The piezoelectric 1-DOF cantilever based liquid pumping system is introduced [25,26] and the performance is enhanced with 2-DOF rectangular cantilever resonant system (2-DOF RCR) in [27]. No works have been reported so far to improve the performance of 2-DOF cantilever shaped resonators in determining the density and viscosity of liquids.…”
