Imagine a wearable device so thin it's less noticeable and lighter than a Band-Aid but can track and record important health information. According to some University of Houston researchers, you might not need to imagine it at all.

A recent paper, which ran as the cover story in Science Advances, identified a wearable human-machine interface device that is so thin a wearer might not even notice it. Cunjiang Yu, a Bill D. Cook associate professor of Mechanical Engineering at the University of Houston, was the lead author for the paper.

"Everything is very thin, just a few microns thick," says Yu, who also is a principal investigator at the Texas Center for Superconductivity at UH, in a release. "You will not be able to feel it."

The device is reported in the paper to be made of a metal oxide semiconductor on a polymer base. It could be attached to a robotic hand or prosthetic, as well as other robotic devices, that can collect and report information to the wearer.

"What if when you shook hands with a robotic hand, it was able to instantly deduce physical condition?" Yu asks in the release.

The device could also be used to help make decisions in situations that are hazardous to humans, such as chemical spills.

Current devices on the market or being developed are much slower to respond and bulkier to wear, not to mention expensive to develop.

"We report an ultrathin, mechanically imperceptible, and stretchable (human-machine interface) HMI device, which is worn on human skin to capture multiple physical data and also on a robot to offer intelligent feedback, forming a closed-loop HMI," the researchers write in the paper. "The multifunctional soft stretchy HMI device is based on a one-step formed, sol-gel-on-polymer-processed indium zinc oxide semiconductor nanomembrane electronics."

The paper's co-authors, in addition to Yu, include first author Kyoseung Sim, Zhoulyu Rao, Faheem Ershad, Jianming Lei, Anish Thukral, and Jie Chen, who are all from UH; Zhanan Zou and Jianliang Xiao of the University of Colorado; and Qing-An Huang of Southeast University in Nanjing, China.

Two Rice University physicists and professors have received a federal grant to continue research on dark matter in the universe.

Paul Padley and Karl Ecklund, professors of physics and astronomy at Rice, have received a $1.3 million grant from the Department of Energy for their research to continue the university's ongoing research at the Large Hadron Collider, or LHC, a particle accelerator consisting of a 17-mile ring of superconducting magnets buried beneath Switzerland and France.

"With this grant we will be able to continue our investigations into the nature of the matter that comprises the universe, what the dark matter that permeates the universe is, and if there is physics beyond what we already know," Padley says in a press release.

This grant is a part of the DOE's $132 million in funding for high-energy physics research. The LHC has received a total of $4.5 million to date to continue this research. Most recently, Ecklund and Padley received a $3 million National Science Foundation grant to go toward updates to the LHC.

"High-energy physics research improves our understanding of the universe and is an essential element for maintaining America's leadership in science," says Paul Dabbar, undersecretary for science at the DOE, in the release. "These projects at 53 different institutions across our nation will advance efforts both in theory and through experiments that explore the subatomic world and study the cosmos. They will also support American scientists serving key roles in important international collaborations at institutions across our nation."

In 2012, Padley and his team discovered the Higgs boson, a feat that was extremely key to the continuance of exploring the Standard Model of particle physics. Since then, the physicists have been working hard to answer the many questions involved in studying physics and the universe.

"Over many decades, the particle physics group at Rice has been making fundamental contributions to our understanding of the basic building blocks of the universe," Padley says in the release. "With this grant we will be able to continue this long tradition of important work."
