Description

 

Graphene Based Wearables and Sensors

Bio: Shideh Kabiri Ameri is a Research Associate in the University of Texas at Austin. Shideh’s current research is focused on two dimensional materials based electronic tattoos for physiological sensing and human machine interfaces.

Shideh received her PhD degree in Electrical Engineering from the Tufts University in 2015. She holds a master and bachelor degree in Physics and AS degree in Medical Laboratory Sciences. Up to date, she is the author and coauthor of over 40 scientific journal articles and conference presentations and inventor of two filed patents. She was selected as a participant in Rising Stars in EECS 2017. Her research has been featured nationally and internationally over more than 20 media news including IEEE Spectrum and BBC.

Abstract: During recent years, there has been a considerable increase in demand for wearable electronics. The latest advances in wearables have been made by electronic tattoos (e-tattoos) which are ultrathin sensors and systems with the thickness of hundreds of nanometers to tens of micrometers. E-tattoos can be laminated on the skin and extract physiological information from the body. This type of ultrathin devices is designed to maintain optimal performance on the microscopically rough texture of the skin and under the strain level of 30% or higher.

Graphene is a two dimensional material made of hexagonal lattice of carbon atoms. Atomic thinness, high electrical conductivity, mechanical strength, optical transparency and biocompatibility of graphene make it a good candidate for e-tattoos and sensors-on-skin applications. In this talk, an ultrathin, optically and mechanically imperceptible graphene based electronic tattoo (GET) will be presented. GET conforms to the microscopic texture of the skin and stay intact with it without tape or adhesive, just with van der Waals force. GET is fabricated using an alternative fabrication method which is time and cost effective. In this talk, GET characterization and applications for electroencephalography (EEG), electrocardiography (ECG), electromyography (EMG), Electrooculography (EOG), sensing skin temperature and hydration level, and human machine interface will be presented. 

Developing such ultra-conformal, multifunctional electronic tattoos can pave the path for the introduction of system-on-skin tattoos. Such sensor-system can greatly benefit athletes, elders, disabled, pregnant women and newborn babies for the health monitoring out of clinical settings.
