Imperceptible Electronic Tattoos for Physiological Sensing

Electronic tattoos (e-tattoos) are wearable electronic devices and sensors, designed to function on soft and stretchable skin. E-tattoos have applications in mobile healthcare, human machine interface, assistive technology and internet of things. To date, development of truly imperceptible and skin-conformal e-tattoos has remained as a challenge. Conformability to skin which results in higher effective area of sensor and consequently higher sensing quality, can be achieved by lowering the overall thickness of e-tattoos. Research shows that to achieve full conformability the thickness of electronics must be less than 500 nm, however; using conventional electronic materials such as semiconductor, metal and insulator films in fabrication of e-tattoos induces limits in lowering their overall thickness. This is because at such thickness the mechanical characteristics of electronics is not any more dominated by soft and flexible polymeric substrates but by the rigid and fragile semiconductor, metal and insulator films, used in the fabrication of such electronics. To address this challenge we turned to two dimensional materials, to realize ultrathin, fully conformal, optically and mechanically imperceptible e-tattoos. Using graphene which is monolayer of carbon atoms and electrically conductive, optically transparent, mechanically strong and biocompatible material, we developed a multimodal electronic tattoo sensors with less than 500 nm thickness. Graphene electronic tattoo (GET) is optically about 85% transparent in optical region and more than 30% stretchable. The areal mass density of GET is small enough to allow attaching the GET to skin just by van der Waals force, therefore; there is no need to adhesives and tapes. GET has been applied for skin hydration and temperature sensing and electrophysiological measurements such as electrocardiogram (ECG), electromyogram (EMG), electroencephalogram (EEG). 

Shideh Kabiri Ameri is a postdoctoral fellow 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 began her academic education as a Medical Laboratory Sciences student at the Iran University of Medical Sciences, where she gained comprehensive basic knowledge in medical sciences, beneficial for pursuing her future research goals in the field of bio-electronics. In the Iran University of Medical Sciences, she had chance to study and learn biochemistry, cellular and molecular biology, hematology, immunology, microbiology, virology, pathology, etc. After receiving her AS degree, Shideh continued her academics in the field of Physics, Solid State, in order to obtain theoretical background and knowledge in physics of electronic devices. She graduated with the first rank in bachelor and the second rank in master in her class and obtained experimental experiences and skills in electronic device fabrication by working toward her master thesis at Thin Films and Nano-electronics Laboratory in the University of Tehran. Shideh received her PhD degree in Electrical Engineering from the Tufts University in 2015. Having wide interdisciplinary background, she focused her research on graphene based devices for electronics, sensing and biotechnology during her PhD. Up to date, she is the author and coauthor of 15 scientific journal articles, 21 conference presentations including a talk in International Electron Device Meeting (IEDM) 2016 and inventor of two filed patents. Her research has been highlighted by IEEE Spectrum and received coverage by national and international media.
