My research lies at the interface of electronics, material science, bioengineering and additive manufacturing. I am using various printing technologies (aerosol jet, inkjet and bioprinting) to develop flexible and stretchable bio- and nano-electronic devices (bio-stimulant platform, drug delivery, sensors, strain gauge, antenna, transistor etc.) on inexpensive substrates namely paper, plastic or commercial plasters. My efforts are directed towards (i) developing printing processes to fabricate high-resolution, high-accuracy and high-performance bioelectronic devices; (ii) formulating materials to impart desired functionalities; and (iii) fabricating two- and three-dimensional multilayer interfacial structures with good mechanical robustness.
The vision for the future of electronics encompasses devices that are lightweight, conformal, flexible, stretchable and low cost. The new generation nanoelectronics is already a multi-million market and expected to grow at rapid speed even further, with applications in automotive, consumer electronics, wearables, Internet of Things (IoT), packaging and biomedical industries. My research focuses on printing routes for fabricating quasi-2D and 3D nanoelectronics for multimaterial, interfacial and multifunctional devices.
3D bioprinting refers to simultaneously writing living cells and biomaterials in a prescribed layer-by-layer stacking organization. Bioprinting route opens up the possibility to build 3D tissue engineering scaffolds to help address diverse health problems. I am working with hydrogel materials with focus on scaffold- based and -free tissue printing, development of new bioinks, organ-on-a-chip models. Aim is to understand the physics of bioprinting processes.
Bioelectronic opens door to fabricate new-age devices where electronic and biomaterials co-exist in synergy. The coupling of electronics with biology can work in two ways. Electronic signals can guide the biological events in a controlled environment, thus replicating the natural phenomenon to study/creat new phenomenon. On the other hand, nanoelectronic devices can help extract relevant information from biological processes to understand the mechanisms involved; thus furthering the healthcare field. I am trying to understand how inorganic electronic materials interface with biological species to make novel sensors, biomedical and point-of-care devices.
