Project Description
The primary objective of this project is to deliver a 1MHz, 60 V peak-peak amplifier circuit in a small form factor, that can be controlled via the web. The amplitude of the amplifier signal must be variable between 0 - 60 Vp-p (ideally), and the circuit should operate in the frequency range of 10kHz - 1MHz. The amplitude and frequency of the signal should be modifiable by the web application. The secondary objective is to show that the circuit can generate an electric field strong enough to separate dielectric particles in a fluid.
Exciting new research has shown that small dielectric particles can be separated from a fluid through dielectrophoresis (DEP). DEP can be defined as the separation of particles that have different effective permittivities. By applying a non-uniform electric field, some particles feel an attractive force while others feel a repulsive one or nothing at all, depending on their permittivity. The goal of this project is to create a circuit that can generate a non-uniform electric field strong enough to separate small particles (on the micron scale) in a fluid, and have the level of separation be controlled via a web application. There are many biomedical applications that can utilize this phenomenon, especially in lab-on-a-chip products.
Throughout this project we have and will continue to explore: biomedical applications, circuit simulation, web-based design, embedded systems, PCB design and fabrication, and high speed test and measurement.
