My past and present research experience with the projects I have undertaken.

Advanced Piezoelectric Skin for Pulse and Patient Monitoring

May, 2026 – September, 2026

With the control of the RPM of the collector and the concentration of BTO nanoparticles, a much more sensitive piezoelectric fibre is achieved. Deposition of Au over a PDMS substrate enables us to achieve true flexible and sensitive sensor. A custom flexible PCB housing, an nRF52840, a signal amplifier circuit and an ADC were used to read the signals, process them, and broadcast them via wifi. Further spatial data collection was implemented using a cross-bar electrode system and a multiplexer.

This project is part of the JST LOTSU PROGRAMME, in the Someya-Jimbo Group Electronic Skin Lab, University of Tokyo, Japan. Under the supervision of Prof.Soutik Betal (IITD), Prof.Takao Someya (UTOKYO), Prof.Tomoyuki Yokota (UTOKYO).

Piezoelectric Skin

July, 2025 – Present

This project focuses on pressure sensing and the improvement of sensor sensitivity. While several pressure-sensing mechanisms exist, such as piezoresistive and piezocapacitive sensors, piezoelectric sensors offer distinct advantages, including the absence of a requirement for an external voltage source, lower power consumption, and the ability to function as energy harvesters.

In the Laboratory of Nanorobotics and Medical Devices, under the supervision of Prof. Soutik Betal, we investigate the influence of laboratory-synthesized barium titanate (BTO) nanoparticles incorporated into electrospun PVDF nanofibers. In parallel, we design the analog front-end circuitry for signal acquisition and data presentation, targeting wearable device applications.

Translation and Clinical Evaluation of Auditory Devices (Bone Conductive Glass)

July, 2025 – January, 2026

Here, the project focuses on the development of a wearable system in the form of smart spectacles for individuals with hearing and visual impairments. Human hearing occurs through vibrations transmitted via the eardrum into the cochlear fluid. Since the cochlea is embedded within the skull, auditory information can also be transmitted through mechanical vibrations conducted via bone, particularly through the temporal bone of the ear. This principle enables hearing through bone conduction.

The system utilizes bone conduction transducers to deliver audio signals and is designed as a multimodal wearable platform. It integrates two bone conduction transducers, two MEMS microphones, two inertial measurement units (IMUs), two audio driver circuits, a camera module, and an ESP32-S3-R8 microcontroller. The ESP32-S3-R8 processes visual data from the camera to assist visually impaired users and audio signals from the microphones to support hearing-impaired users.

This project was carried out under the supervision of Prof. Soutik Betal and Prof. Dinesh Kalyanasundaram.

Electrochemical Sensor On-Chip Model

October 1, 2023 – July 12, 2024

Potentiostats play a vital role in electrochemistry. Rapid analysis, such as cyclic voltammetry and differential pulse voltammetry, helps in understanding the properties of a concentrated solution on a lab scale. Reliable handheld potentiostats are the key requirements for the transformation of these technologies from laboratories to point-of-care applications with a much more affordable price range. Here, we are developing an On-the-Fly use potentiostat, small, hand-held, open source, battery powered with extended voltage application and current measurement range. Furthermore, it can be programmed to run other voltammetry analyses that are similar to our needs. This project was mentored by Dr.Santanu Talukdar, Assistant Professor, Indian Institute of Science Education and Research, Bhopal. We participated in the ICMNSS (International Conference for Micro Nano and Smart Systems) student design competition and won first place with a cash prize of 50K INR.

Mechatronic System for Sorting of Waste Plastic

May 08, 2023– July 28, 2023

This project is the continuation of my previous winter internship. Since the Arduino didn't meet our frequency requirements we moved on to trying the redesigned circuit with Raspberry Pi and Nvidia Jetson TX 2. I was also given some tasks to work on DANFOSS VFD for control of the roller (Via MODBUS communication protocol). The tasks I had were also a mix of mechanical and physics (Spectroscopy to scan over a variety of plastics) background. This project was mentored by principal scientist Dr.Madan Kumar Laskshmanan from the Central of Electrical Engineering Research Institute, Council of Scientific Industrial Research, Chennai.

Study and Interface of Pnuematic Valve System

December 5, 2022– December 25, 2022

This project aims to create a slave program using Arduino, python, and FESTO pneumatic valves for the main goal of segregation of varieties of materials. I had a chance to study the different types of pneumatic valves, their parameters, and their working. This project was mentored by Principal Scientist Dr.Madan Kumar Laskshmanan, Principal Scientist from the Central of Electrical Engineering Research Institute, Council of Scientific Industrial Research, Chennai.

Electrochemical Sensor On-Chip Model

May 8, 2022 – July 30, 2022

This project, which is currently working on, involves 3 electrode systems and a circuit developed which is similar to a potentiostat to run some basic voltammetric analysis. The goal is to make an affordable and transportable miniature potentiostat. This project is mentored by Dr.Santanu Talukdar, Assistant Professor, Indian Institute of Science Education and Research, Bhopal.

These are the projects I have worked on for my academic purposes and on a few weekends.

Computer Vision: Developed ML code to read and recognise hand signs and control simulated objects with 98% accuracy. Slide and report here.
Introduction to MEMS: SPE simulation (2 different geometries) was done in COMSOL. Report file here.
ELL832 (Special topics in analog circuits IIT Delhi): This is my end-term project report of the ELL832 course at IIT Delhi. We were tasked with designing a fully differential amplifier (with 5GHz UGB) for a Tow-Thomas biquad filter operating at a cutoff frequency of 500MHz. The simulation was done in Cadence using the TSMC 65nm technology node. Report file here.
ELP830 (Semiconductor Processing Laboratory): This project involves Designing Masks for lithography for devices such as TLM, Hallbar, Contact Resistance, and NMOS. The design was done using KLayout software. The design file is available as a PDF here.
