We are very delighted our wearable blood pressure work (nature nanotechnology 2022) was highlighted among the ‘remarkable discoveries’ of 2022. We look forward to advancing the concept so it becomes widely available and help many of the millions at risk or suffering from hypertension/cardio-vascular issues.
We report the development of graphene electronic tattoos for continuous blood pressure monitoring using bio-impedance modality. Machine learning techniques were implemented to get Grade A accuracy results, which is the highest grade of the IEEE standard.
Several media outlets have reported on this significant achievement.

A thorough review of resistance switching devices, aka, memristors is now in Science.
This work was led by Mario Lanza at KAUST with many other leading scholars contributing to the review article.

Our latest work on non-volatile ‘zero-power’ switches has been published in nature electronics.
This switches feature DC-500GHz bandwidth and can transmit data at 100Gb/s at ~300GHz. They can also be switched in less than a nanosecond. This performance meets/exceeds the IEEE 6G standardization target.
The collaborative work was the focus of the dissertation of former PhD student Myungsoo Kim, who is now a professor at UNIST.

Rohde & Schwarz and FormFactor Support UT Austin in Research on Improved RF Switches
The RF Switches were pioneered by Akinwande laboratory based on atomically 2D materials such as h-BN and MoS2. This research has resulted in many publications at Nature electronics, Nature communications, Advanced materials, and Nanoletters.
Visual memory paper led by postdoc scholar Dr. Seongin Hong and with collaborators from Yonsei University and SKKU; now published in ACS Nano and made the cover article.
Congrats Dr. Hong and collaborators.
Dr. Hong is now a Professor at Gachon University in South Korea as of 2022.
2020 PhD graduate, Dr. Myungsoo Kim has won the UT-Austin Ben Streetman PhD Prize “For Outstanding Research by a Graduate Student in Electronic and Photonic Materials and Devices.” CONGRATS!
Myungsoo began his faculty career in 2021/2022 as an Assistant Professor at UNIST in South Korea.
Dr. Kim authored several high-profile papers including 5G switches in Nature Electronics, and high-frequency applications of 2D memristors at the IEDM.
Wall street journal interviewed Professor Akinwande and featured his research and a picture with research scholar Dr. Kireev in an article on 2D materials.
Also ACM Magazine quoted Prof. Akinwande in an article on Chip scaling and 2D materials.
In original discovery research reported in nature nanotechnology, we discover the underlying physics (metal bonding to atomic vacancy) behind atomristor or memristor effect in atomic sheets using MoS2 as a model. This is arguably the smallest atomic memory unit (1nm feature size).
Work led by Dr. Saban Hus and with several distinguished collaborators.

A single atomically-thin layer of hexagonal boron nitride shows that thinner is better with regards to radio-frequency switching applications. This work is now published and is based on our earlier discovery of atomristors.
Fruitful collaboration between UT-Austin (lead grad student, Myungsoo Kim) and CNRS in Lille led by Emiliano Pallecchi and Henri Happy.

The combination of 2D materials and Silicon arguably represents the biggest application of these materials in advancing commercial semiconductor applications.
As such, a review article on the progress, opportunities and challenges for graphene/2D materials integration on Silicon for heterogeneous 3D nanotechnology was commissioned and is now available at Nature journal.
This is a balanced review featuring academia and industry leaders in the area of 2D materials and Silicon technology.
