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.
Wearable Blood Pressure Monitoring in Nature Nano. Global media interest.
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.
Work is now published in Nature Nanotechnology, and is a collaboration with Roozbeh Jafari’s group at Texas A&M. Postdoc Scholar Dr. Dmitry Kireev is the first author.
Several media outlets have reported on this significant achievement.

Review of memristors and applications in Science.
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.
We describe memristors made from 2D materials, a phenomenon we discovered and can be utilized for various applications including 5G/6G/THz ‘zero-power’ switches.

MoS2 6G Switches (500GHz, 100Gb/s) in nature electronics
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.

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.
Nature Nano: Single atom (smallest) memristor
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.
