“…A novel valve less piezoelectric pump is introduced, utilizing a rhinoceros horn and V-channel combination. By capitalizing on the distinct pressure loss coefficients from the convex and concave curved segments of the rhino horn and V-channel, the pump achieves remarkable unidirectional flow efficiency, resulting in high output performance [26]. Designed for human heart rate (HR) monitoring, a MEMS capacitive pressure sensor array is combined with signal conditioning circuitry.…”

Diabetes is a metabolic disorder, if a person is once diagnosed it’s not resolvable and is identified by variations in glucose concentration levels. We are designing an osmotic pressure sensor for the continuous glucose monitoring system. For this, microbridge and microcantilever with different principles are optimized and suitable is integrated to pressure sensor by using FEM tool, the performance analysis of the pressure sensor are analyzed on the aspects of sensitivity and non-linearity

According to the bluffbody bypass effect, the irregular bluffbody can be used to improve the valveless piezoelectric pump. This paper designs a semi-arc bluffbody based on the bluffbody bypassing principle to alleviate the phenomenon of fluid backflow. The fluid passes through the shape of the antique tower to further enhance pumping efficiency. A positive fluid flow mechanism in the pump cavity is theoretically derived. The simulation of the velocity and pressure distribution in the tower-shaped channel of the pump cavity leads to the conclusion that the forward flow has better performance than the reverse flow, and the correctness of the theory is also verified. Experiments further proved that the volume of fluid in the forward direction was reduced by 10.8% when compared to the reverse direction. The study of the height of different semi-arc bluffbody and the angle of the tower trough shows that as the height and angle increase, the flow rate grows first and then reduces. The maximum flow rate is 243.83 ml/min when the bluffbody height is 4 mm and the channel angle is 20° (220 V, 85 Hz).

Valveless pumps are gaining importance in various fields. However, the reflux phenomenon can reduce pump performance and limit its application. This article proposes a dual outlet composite drainage structure valve-less piezoelectric pump with multiple semicircular arc structures within the flow channel to address this issue. The operating methods are explained, and the pump output flow rate formulation has been derived. The ANSYS CFX was used to simulate flow conditions in various directions. A prototype pump was then produced and tested using 3D printing technology. The results show that the flow rate gets a maximum state of 189.6 mL/min under a voltage of 200 V and a frequency of 50 Hz.
