Micro-Nano Devices@ IIIT Hyderabad

Electronics & Sensors, Biomimetic Engineering Lab

Micro-Nano Devices Research is an amalgamation of different areas of science and engineering.

Analog VLSI Design

Design of analog Circuits for Bio & Sensing Applications.

Using Cadence and 180 nm CMOS technology for designing custom circuits for system on a chip. Design includes low power design, bio-mimetic design, mixed signal design, integrating silicon sensing, electronic noise characterisation and reduction. Lab is also looking into the process variation, other process technology, chip testing techniques and different types of devices.

For students: Interest and knowledge of electronics, semi-conductor physics, circuit design and some statics is preferred.

Micro/Nano Fabricated Devices

Micro/Nano-fabrication techniques.

Fabricating sensors and integrating with silicon chips to produce System-On-A-Chip. The work includes characterising different nano materials, polymers and fabricating devices in silicon, glass, polymer. Devices modelling is done using FEM and also prototyped. The devices include chemical/gas sensor, electrophysiological signal sensing, bio-based sensors, uTAS (micro-total analysis system) and microfluidics.

For students: Liking towards bench experimental work, strong fundamentals in physics, chemistry, inquisitiveness and commitment towards increasing their knowledge is required.

Sensor for Environment Monitoring & Wearable Biomedical Devices

Developing cutting edge techniques for power harvesting, research into new ways of sensing, development of smart sensor devices, integrating sensors with ML and IoT, focus on portable bio-medical instrumentation, catering to increasing bio-medical demands.

For students: Keen interest in electronics, circuit design, fabrication, experimental work, simulation tools is needed.
