Cheap paper and pencil-based medical wearables could one day replace expensive health monitors.

Chameleons are famous for their color-changing abilities. Depending on their body temperature or mood, their nervous system directs skin tissue that contains nanocrystals to expand or contract, changing how the nanocrystals reflect light and turning the reptile’s skin a rainbow of colors.
Inspired by this, scientists at the Pritzker School of Molecular Engineering (PME) at the University of Chicago have developed a way to stretch and strain liquid crystals to generate different colors.
By creating a thin film of polymer filled with liquid crystal droplets and then manipulating it, they have determined the fundamentals for a color-changing sensing system that could be used for smart coatings, sensors, and even wearable electronics.
Very true.
And as in most applications of #MachineLearning, healthcare #AI systems are extremely data-hungry.
Fortunately, a slew of new sensors and data acquisition methods — including over 302 million wearables shipped in 2019 — are bursting onto the scene to meet the massive demand for medical data.
From ubiquitous biosensors, to the mobile healthcare revolution, to the transformative power of the Health Nucleus and their 100+ program, converging exponential technologies are fundamentally transforming our approach to #healthcare.
A glove that translates sign language into speech in real time has been developed by scientists — potentially allowing deaf people to communicate directly with anyone, without the need for a translator.

The wearable device contains sensors that run along the four fingers and thumb to identify each word, phrase or letter as it is made in American Sign Language.
Those signals are then sent wirelessly to a smartphone, which translates them into spoken words at a rate of one word per second.
A team of researchers has designed a new type of wearable — and e-skin — that is bacterial resistant and can detect emotion through micro face movements.
Now that the world is in the thick of the coronavirus pandemic, governments are quickly deploying their own cocktails of tracking methods. These include device-based contact tracing, wearables, thermal scanning, drones, and facial recognition technology. It’s important to understand how those tools and technologies work and how governments are using them to track not just the spread of the coronavirus, but the movements of their citizens.
Contact tracing is one of the fastest-growing means of viral tracking. Although the term entered the common lexicon with the novel coronavirus, it’s not a new practice. The Centers for Disease Control and Prevention (CDC) says contact tracing is “a core disease control measure employed by local and state health department personnel for decades.”
Traditionally, contact tracing involves a trained public health professional interviewing an ill patient about everyone they’ve been in contact with and then contacting those people to provide education and support, all without revealing the identity of the original patient. But in a global pandemic, that careful manual method cannot keep pace, so a more automated system is needed.

In the last few years, most of the data such as books, videos, pictures, medical and even the genetic information of humans are moving toward digital formats. Laptops, tablets, smartphones and wearable devices are the major source of this digital data transformation and are becoming the core part of our daily life. As a result of this transformation, we are becoming the soft target of various types of cybercrimes. Digital forensic investigation provides the way to recover lost or purposefully deleted or hidden files from a suspect’s device. However, current man power and government resources are not enough to investigate the cybercrimes. Unfortunately, existing digital investigation procedures and practices require huge interaction with humans; as a result it slows down the process with the pace digital crimes are committed. Machine learning (ML) is the branch of science that has governs from the field of AI. This advance technology uses the explicit programming to depict the human-like behaviour. Machine learning combined with automation in digital investigation process at different stages of investigation has significant potential to aid digital investigators. This chapter aims at providing the research in machine learning-based digital forensic investigation, identifies the gaps, addresses the challenges and open issues in this field.
“ “The monitoring of human health and well-being with the use of wearables is considered critical in the next generation of biomedical devices,” write the authors. “[But] most existing paper-based devices are designed for one-time use only, functioning under relatively intense capillary flow into the paper, which ceases upon saturation… [Our approach] can function as a key part of a platform for long-term sweat sampling and biomarker monitoring.””
Researchers have designed a paper-based wearable device that can monitor your sweat for 10-days at a time to detect important information about your health.
A team of researchers at Université de Sherbrooke with assistance from a group at Exonetik Inc., has created a wearable supernumerary robotic arm that adds functionality for common human tasks. In their paper published in IEEE Spectrum, the group describes their robotic arm, its abilities and their plans for expanding its functionality.
A supernumerary robotic device is of a type that adds functionality to an existing system. In this case, the team in Canada added a third arm and associated three-fingered hand to a human subject.
The bottom part of the robot is strapped to the waist and hips of the user, anchoring it in place. The robot arm extends from its anchor and performs functions as the user either watches or carries out his or her own activities. The arm is motivated by magnetorheological clutches and hydrostatic transmissions, giving it three degrees of freedom. It does not weigh much, either, just four kilograms. But that is because it has a tethered power/control source that remains on the ground. It also is remotely controlled by another person standing nearby. Future plans call for semi-autonomous control.
We’ve always had a soft spot for supernumerary robotic limbs here at The Verge, but this latest example of the genre is one of the most impressive we’ve seen to date. Designed by researchers at the Université de Sherbrooke in Canada, it’s a hydraulic arm that sits on the wearer’s hip and uses a three-fingered manipulator to carry out a range of tasks.
