Electronics & Embedded Systems

Prototyping & Circuit Design

I design and prototype analog and digital circuits and troubleshoot electrical systems for optimal performance. My work includes integrating electrical components into microfluidic and mechanical systems.

Microcontroller Integration & Automation

I program microcontrollers (e.g., Arduino) to automate devices, monitor systems, and optimize performance for real-time control.

Power Systems & Actuation

I source power supply systems and integrate actuators (e.g., piezoelectric elements, solenoids) for precise mechanical control in prototypes.

Testing & Validation

I use diagnostic tools like oscilloscopes and multimeters to test and validate circuits, ensuring reliability and meeting regulatory standards.

Tools & Software

I am proficient with simulation software for signal processing (MATLAB, Simulink) and automated testing (PSpice, LabVIEW).

I use data acquisition systems (e.g., LabJack) to integrate pressure sensors into microfluidics systems

Electrical Components used in my Acoustic Droplet Generator

DC Power Supply

The DC power supply, specifically the "Kungber 30V 10A lab DC benchtop power supply," provides the necessary power with high precision for the system. It ensures the accurate operation of the operational amplifier & the solenoid.

Waveform Generator

SIGLENT’s SDG1000X waveform generator, provides a diverse range of high-fidelity signals. Its ability to generate various waveforms with specific characteristics contributes to the controlled and precise generation of droplets.

Piezoelectric Buzzer

The piezoelectric buzzer serves as the actuator responsible for transforming electrical signals into mechanical vibrations necessary for droplet formation. A commercially available piezoelectric buzzer is used for this.

Push Pull Solenoid

The linear solenoid actuator adds to vibrations necessary for droplet formation, supporting the piezoelectric buzzer. A commercially available solenoid is used for this.

OpAmp + Breadboard

Signals from the waveform generator were fed into a breadboard where they were amplified by an operational amplifier before finally being sent to the PZT. This step was implemented to maximize the buzzing of the PZT.
