Humane’s device swap smartphones for a wearable that contains a projector.

Wearable devices like Spiderman’s suit that are thin and soft, yet also feature electrical and optical functionalities? The answer lies in producing novel materials that go far beyond the performance of existing materials and developing technology that enables the precise control of the physical properties of such materials.

Separating transition metal dichalcogenide (TMD) into a single layer just like graphene makes it transform into a thin, two-dimensional (2D) film material that exhibits the characteristics of highly performing semiconductors. By stacking two disparate TMD layers, different combinations of TMD types and stacking methods can produce unique properties.

For this reason, 2D semiconductors based on heterostructures are attracting attention as an important next-generation material for the electronics industry throughout academia and industries around the world. However, it is still quite challenging to commercialize them due to the difficulty of controlling with precision the physical properties of their quasiparticles.

Able to stretch, squish, and bend, this flexible OLED panel could drive future wearable and implantable electronic systems.

A Korean research team has developed a large-scale stretchable and transparent electrode for use as a stretchable display. The Korea Institute of Science and Technology (KIST) announced that a research team, led by Dr. Sang-Soo Lee and Dr. Jeong Gon Son at KIST’s Photo-Electronic Hybrids Research Center, has developed a technology to fabricate a large-area (larger than an A4 sized paper) wavy silver nanowire network electrode that is structurally stretchable with a high degree of conductivity and transparency.

Transparent electrodes, through which electricity flows, are essential for solar cell-and touchscreen-based display devices. An indium tin oxide (ITO)-based transparent electrode is currently commercialized for use. The ITO-based transparent electrode is made of a thin layer of metallic oxides that have very low stretchability and is very fragile. Thus, the ITO electrode is not well suited for flexible and wearable devices, which are expected to quickly become mainstream products in the electronic device market. Therefore, it is necessary to develop a new transparent electrode with stretchability as one of its main features.

A silver nanowire is tens of nanometers in diameter, and the nano material itself is long and thin like a stick. The small size of the nanowire allows it to be bent when an external force is applied. Since it is made of silver, a silver nanowire has excellent electrical conductivity and can be used in a random network of straight nanowires to fabricate a highly transparent and flexible electrode. However, despite the fact that silver nanowire is bendable and flexible, it cannot be used as a stretchable material.

Researchers from the Harbin Institute of Technology and Southern University of Science and Technology have fabricated bifunctional flexible electrochromic energy-storage devices based on silver nanowire flexible transparent electrodes.

Publishing in the International Journal of Extreme Manufacturing, the team used silver nanowire flexible transparent electrodes as the current collector for a bifunctional flexible electrochromic supercapacitor.

This bifunctional flexible device can exhibit its energy status through color changes, and can serve as an energy supplier for various wearable electronics, such as physiological sensors. The findings could have a widespread impact on the future development of smart windows for energy-efficient buildings.

The study authors claim their microscope can provide colored real-time images of hard-to-reach parts of the spinal cord that couldn’t be accessed previously.

Pain is a powerful feeling but have you ever wondered how pain works on a cellular level? Well, a team of scientists at the San Diego-based Salk Insitute has actually figured out a way to see the internal neural mechanism associated with pain.

In their recently published study, they propose wearable microscopes using which they were able to check how nerve cells in the spinal cord of mice process pain signals.

New technologies can greatly advance research in various fields, including medicine and neuroscience. In recent years, for instance, engineers have created increasingly sophisticated devices to record brain activity and other biological signals with high precision.

A multi-disciplinary research team at University of California, Los Angeles (UCLA) and other institutes in the U.S. have recently developed the Neuro-stack, a new wearable technology that can record the activity of single neurons in the brain as a human being is walking or moving. This device, presented in a paper published in Nature Neuroscience, could help to gather valuable insight about neuronal activity during walking, while also potentially improving treatments for brain disorders.

“Our study was motivated by the need for smaller size and more flexible devices for clinical neuroscience,” Dejan Markovic, one of the researchers who carried out the study, told Medical Xpress. “Our primary objectives were to make a device that is small enough to be wearable, for mobile experiments, and to provide broadband recordings including local field potentials and single units.”
