Chapter
Printed electronics (PE) technology is a highly matured technology borrowed from the printing industry. PE is a set of printing methods to create electrical devices on various flexible substrates. PE typically uses standard printing equipment suitable for defining patterns on material, using techniques such as screen printing, flexography, gravure,...
Article
Flexible strain sensors have been used in myriad of applications with studies in human physiological monitoring, robotic operation, and human–machine interaction being intensively explored in recent years. Achieving a cost effective, high-performance flexible strain sensor with high sensitivity, and capable of large-scale production have great impo...
Article
Endogenous electric field is known to play significant part in wound closure and healing of wounds which takes place through its process of protein synthesis and migration of cells to the centre of the wounds due to wound currents. Many clinical studies have showed that electrical stimulation with bio-mimicking exogeneous current through electrodes...

Chronic wound care has always been a major challenge for healthcare professionals and is a significant public health crisis. Electrical stimulation (ES) therapy is an effective alternative treatment for chronic and acute dermal wounds by promoting electrotaxis of different types of cells during different stages of wound healing. In the present work...
Article
Personalized mobile healthcare integrated with various wearable devices has become a significant area of interest in the present era. In the current research work, a flexible, wearable and disposable paper-based continuous skin temperature monitoring sensor for early medical prognosis and accurate diagnosis of body temperature-related ailments, suc...
Chapter
Development of successful flexible electronic devices desires excellent compliancy between the deposited inorganic thin-film materials and flexible polymeric substrates as the film-substrate assembly is conformally mounted over uneven surfaces. Several physical parameters control the optimal surface science at the metal-polymer interface and result...
Article
Accurate measurement and monitoring of respiration is vital in patients affected by severe acute respiratory syndrome coronavirus – 2 (SARS-CoV-2). Patients with severe chronic diseases and pneumonia need continuous respiration monitoring and oxygenation support. Existing respiratory sensing techniques require direct contact with the human body alo...
Article

Integration of thin film inorganic sensors over curved surface requires flexibility of the thin film assembly along with the substrate for various applications. In the present study, a micro thin film flow sensor was fabricated over a soft biocompatible PDMS elastomer. A non-planar topology was used for proper orientation of the thin film buckles a...
Article
Full-text available
The tunable mechanical and physical properties of Polydimethylsiloxane (PDMS) are commonly utilized for studying cellular dynamics. However, the inherent hydrophobic nature of PDMS limits its application as cell culture films. Various surface modification techniques render PDMS films hydrophilic which alters the surface chemistry, elasticity, rough...
Article
Crack free electrically continuous metal thin films over soft elastomeric substrates play an integral part in realization of modern day flexible bio-electronics and biosensors. Under non-optimized deposition conditions, delamination and/or cracking of the top film as well as the underlying soft substrate hinders optimal performance of these devices...
Article
Micromachining of a polydimethylsiloxane (PDMS) microstructure by wet chemical etching is explored for microelectromechanical systems (MEMS) and microfluidic applications. A 100 μm thick PDMS film was patterned with different microstructure designs by wet chemical etching using a N-methyl-2-pyrrolidone (C16H36FN) and tetra-n-butylammonium fluoride...

Development of flexible sensors/electronics over substrates thicker than 100 mu m is of immense importance for its practical feasibility. However, unlike over ultrathin films, large bending stress hinders its flexibility. Here we have employed a novel technique of fabricating sensors over a nonplanar ridge topology under pre-stretched condition whi...
Conference Paper
Cells are complex entities which not only passively sense external stimuli (viz. chemical, optical or mechanical) but also interact with extracellular matrix (ECM) by regulating cellular behavior such as growth, proliferation, migration, etc. Monitoring cell growth and migration of adherent cells becomes a crucial factor in determining cell-cell an...
Article
Full-text available
Flexible electronics and other polymer-based devices demand effective metallization of thin metal films over soft substrates. However, metallization of thin films over soft elastomers such as polydimethylsiloxane (PDMS) often leads to crack formation and morphological changes in the film as well as over the elastomeric surface offering limited appl...
Article
Development of micro-fabrication technology, along with an ever increasing demand for reliable, low cost clinical health care has led to the realization of various BioMEMS devices. Present study aims at developing a flexible flow sensor on polymer substrate to monitor real-time blood flow and determine plague formation satisfying sensitivity, bioco...
Article
Flexible MEMS sensor over biocompatible polymer substrates such as PDMS finds numerous biomedical applications. Present article deals with the fabrication challenges that are faced in the realization of metal thin film patterns over PDMS for development of flexible/implantable sensors. In future these miniature flexible sensors have potential appli...
Article
Successful realization of various BioMEMS devices demands effective surface modification techniques of PDMS elastomer.

Arterial disease, especially Coronary Artery Disease (CAD) is one of the leading causes of premature morbidity and mortality. During the flow, blood not only interacts with vessel wall mechanically but also chemically which modulates the plaque formation in blood vessel thus leading to coronary artery diseases. Here we propose to simulate a MEMS ba...
Article
Elastomers by granting mechanical flexibility have provided huge potential to be exploited in MEMS (Micro electro-mechanical-systems) technology. The large mismatch in thermo-mechanical properties of thin-film and elastomeric base is a major cause of buckling in the bi-layer system. The wrinkle patterns of the buckled film can cause malfunctioning...
