EE Seminar| Emerging flexible and wearable electronic sensors based on nanomaterials

Start Date: May 21, 2017
End Date: May 21, 2017

By Professor Sushmee Badhulika (Indian Institute of Technology (IIT), Hyderabad, India)
 
ABS: Nanomaterials exhibit extraordinary mechanical, thermal, and electronic properties which enable them to be used extensively in numerous applications such as solar cells, field-effect transistors, batteries, super capacitors chemical and biosensors. However most modern day nanomaterials based devices are on rigid substrates and thus cannot be integrated with soft, flexible and curvilinear surfaces thus limiting their application in fields such as flexible displays, wearable electronics, bio-implantable devices and microfluidic devices. This talk focuses on the development of nanomaterials based devices on flexible substrates which have widespread utility in biomedical devices, artificial electronic skin, smart packaging and gaming applications. In addition several solvent-free fabrication methods of developing these flexible devices would be discussed. Being solvent-free, these approaches do not face issues of eco-unfriendly chemicals, surfactants and poor solubility that often hinder conventional methods of fabrication such as screen printing and inkjet printing thereby limiting throughput. Rapid development of electronics has led to a decrease in the active lifetime (due to the availability of upgrades) of electronic devices as well as an increase in the consumption of non-renewable natural resources which leads to environmental contamination and adversely affects human health. The second part of the talk would therefore address one of the approaches of mitigating this challenge i.e., by development of low cost, paper based all carbon eco-friendly electronics.
