Transcranial Focused Ultrasound (tFUS) for neuromodulation

Transcranial Focused Ultrasound (tFUS) is a non-invasive technique for brain stimulation that offers higher spatial resolution and the potential to stimulate deep-brain structures. The reflection, diffraction, and distortion encountered by the ultrasound waves due to the inhomogeneity of the skull bone pose the biggest research challenge in tFUS. We work on developing novel ultrasound transducers that can minimize the skull’s effect while focusing ultrasound onto deep-brain structures.


MEMS/NEMS design and fabrication

MEMS/NEMS devices assimilate both electrical and mechanical functionalities at the micro/nano scale. The optimal design and fabrication of these devices are essential to improve their efficiency. We work on analytical and finite element modelling of MEMS/NEMS devices such as electrothermal actuators, Piezoelectric Micromachined Ultrasonic Transducers (PMUTs), Capacitive Micromachined Ultrasonic Transducers (CMUTs), etc., and fabricate them with our academic/industrial collaborators.


Biosensors and sensors for precision agriculture

Rapid, and in-situ sensing became an integral part of the present-day lifestyle. Sensing solutions offering accurate result at the expense of minimal time is of great importance in sectors such as biomedical, food preserving, agriculture, etc. We engage in developing sensor systems for the detection of food-borne pathogens, disease conditions, and soil parameters. Each of these devices is expected to reach a Technology Readiness Level of 7 (TRL 7), such that appropriate industries can take them up for commercialization.


Wearable and implantable sensors using biomaterials

Biocompatibility is an indispensable criterion for materials used in wearable and implantable applications. One of the key research aspects in this direction is to engineer biocompatible sensing materials and develop sensors & actuators using these materials. Our group is exploring the piezoelectric property of biomaterials such as Bombyx Mori silk, amino acids, etc., and developing sensors, actuators, and transducers with these materials.
