Jet dispenser driven by piezoelectric actuators, based on diamond-shape shell structure without any hinges, was designed and their static and dynamic characters were investigated. The amplifier makes the dispenser small and compact, and operated in a wide range of frequency. In this study, a method to accumulate the amplifyer displacement will present firstly. In the following, dynamic model of a...
In this paper, the model of jet dispensing process is developed by decomposing the dispenser into three parts. This model includes all the important system parameters, such as the fluid viscosity, the diameter and length of nozzle and backflow chamber. In this model, the fluid flow is assumed to be steady state flow at each moment. During the whole jetting process, the fluid flow state changes with...

Intramuscular injections are a common medical procedure performed countless times on a daily basis; however the actual procedure of giving an injection is rather complicated and can be intimidating to nursing students new to the medical profession. The instrumented syringe discussed in this paper was conceived as a tool to help train individuals in proper injection procedure and technique. Utilizing...
Single-needle systems have been used in electrospinning experimental research; however, the low fluid throughput in fiber production has industrial limitations. To meet a high liquid-throughput requirement, several multijet schemes have recently been tested. The main drawback of these schemes is the deterioration of the local electric field at the needle tip due to the influence of other needles in...
In this paper, MEMS based polymeric drug delivery system for the treatment of cardiovascular disorder such as hypertension is presented. The major components of proposed system are drug delivery device, blood pressure sensor, flow sensor, electronic module, and power supply. Drug delivery device consists of piezoelectric actuator and reservoir integrated with side open polymeric microneedles. The...
