EDIT: The output current rating is only 1.5A, so is no good on its own. Quote from: fluorescent on January 01, 2018, 09:26:17 pm -i found this what do you think? !jEo3gTCJ!Pn4DxXqjhjkl-_VDkSSEGVIWOP04tLhMxhBYMJFaAjI - End quote - Looks sensible to me.
Dissected piezo injector driver#
I need such a driver unit to simulate the ECU pulse and frequency.
They need a control driver unit to test it out of car. I talk about piezo injectors made by Siemens or Continental, Bosch.
Try to cut open some spare and dissect it. It is better to re-purpose existing electronics from demolished injector/ecu instead of designing new one. Have opened several different ECUs and haven't found ultrasonic pulsers in them. I would expect that gnd +12v and trigger to be from outside. I haven't experience in car electronics but think if such signal runs trough cables will be huge source for interference. Isn't driver already incorporated into injector? It is strange if driving signal is from outside. I found this what do you think? !jEo3gTCJ!Pn4DxXqjhjkl-_VDkSSEGVIWOP04tLhMxhBYMJFaAjI From preliminary experiments of cell injection of a large number of zebrafish embryos (n = 200), the injector pipette can easily pierce through the cell membrane at a low injection speed and almost no deformation of the cell wall, and with a high success rate(96%) and survival rate(80.7%) This new injection approach shows good potential for precision injection with less damage to the injected cells.Need schematic to build a piezo driver 0-150vĮlectronics > Projects, Designs, and Technical Stuff Furthermore, ultrasonic vibration micro-dissection (UVM) theory is utilized to analyze the piezo-driven cell injection process, and the source of the lateral oscillations of the injector pipette is investigated. Harmful lateral tip oscillations of the injector pipette are reduced substantially without the use of a mercury column. A small piezo stack is sufficient to perform the cell injection process. This new piezo-driven cell injector design relocates the piezo oscillation actuator to the injector pipette which eliminates the vibration effect on other parts of the micromanipulator. A new design of the piezo-driven cell injector is proposed for automated suspended cell injection. In this paper, a new cell injection system for automatic batch injection of suspended cells is developed. Although this technique significantly improves the survival rates of the ICSI process, shortcomings due to the toxicity of mercury and damage to the cell membrane due to large lateral tip oscillations of the injector pipette may limit its application. Recently a new cell injection technology using piezo-driven pipettes with a very small mercury column was proposed and successfully applied in ICSI to a variety of mammal species. Over the past decade, the rapid development of biotechnologies such as gene injection, in-vitro fertilization, intracytoplasmic sperm injection (ICSI) and drug development have led to great demand for highly automated, high precision equipment for microinjection.
