A WiFi Deauthentication Project in a Sleek Package

Posted by in categories: education, internet, security, wearables

Wearable tech has seen an explosion of creativity and applications in the last decade; especially with circuit components getting smaller and cheaper, and batteries getting better and better. Whereas taking phone calls on your wrist was impressive just a few years ago, now, you can experiment with deauthentication attacks on WiFi networks just from this watch: the DSTIKE Deauther Watch SE.

Based on the ESP8266 WiFi microcontroller, this watch is the latest generation of a project to give you a wearable interface for pen testing local WiFi networks. The watch only works on 2.4GHz networks, due to the restrictions of the ESP8266. It comes pre-flashed with the latest ESP8266 Deauther firmware, which is an open-source project! The watch supports four main functions: a deauther attack, which disconnects all local 2.4GHz networks; deauther beacon, used for creating fake networks; deauther probe, to confuse any nearby WiFi trackers; and packet monitoring, which lets you display local WiFi traffic. As you can see, there’s a lot to appreciate in this slick and discreet package.

This watch (and its prior iterations) are made and sold by Travis Lin. Much like the seller emphasizes on the product page, this device is meant for educational purposes, and should be only tested on devices and networks you own. But if this has your curiosity piqued, put on your red hat and check out the wearable devices and other security goodies they have for sale!

Top 10 Interesting ML Dissertations from Ph.D. Students

Posted by in categories: health, information science, robotics/AI, wearables

Choosing interesting dissertation topics in ML is the first choice of Master’s and Doctorate scholars nowadays. Ph.D. candidates are highly motivated to choose research topics that establish new and creative paths toward discovery in their field of study. Selecting and working on a dissertation topic in machine learning is not an easy task as machine learning uses statistical algorithms to make computers work in a certain way without being explicitly programmed. The main aim of machine learning is to create intelligent machines which can think and work like human beings. This article features the top 10 ML dissertations for Ph.D. students to try in 2022.

Text Mining and Text Classification: Text mining is an AI technology that uses NLP to transform the free text in documents and databases into normalized, structured data suitable for analysis or to drive ML algorithms. This is one of the best research and thesis topics for ML projects.

Recognition of Everyday Activities through Wearable Sensors and Machine Learning: The goal of the research detailed in this dissertation is to explore and develop accurate and quantifiable sensing and machine learning techniques for eventual real-time health monitoring by wearable device systems.

Wearables take ‘logical’ step toward onboard control

Posted by in categories: computing, wearables

For all the talk about embedding computers in clothing, here’s an interesting option. Make the clothing the computer, and do it without electricity.

Mechanical engineers at Rice University’s George R. Brown School of Engineering are trying the concept on for size with a set of textile-based pneumatic computers capable of digital logic, onboard memory and user interaction.

Scaling up the production of liquid metal circuits

Posted by in categories: biotech/medical, robotics/AI, wearables

Carnegie Mellon mechanical engineering researchers have developed a new scalable and reproducible manufacturing technique that could accelerate the mainstream adoption and commercialization of soft and stretchable electronics.

The next generation of robotic technology will produce and robots that are safe and comfortable for direct physical interaction with humans and for use in fragile environments. Unlike rigid electronics, soft and can be used to create wearable technologies and implantable electronics where safe physical contact with biological tissue and other delicate materials is essential.

Soft robots that safely handle delicate fruits and vegetables can improve food safety by preventing cross-contamination. Robots made from soft materials can brave the unexplored depths of the sea to collect delicate marine specimens. And the many biomedical applications for soft robots include wearable and , prostheses, soft tools for surgery, drug delivery devices, and artificial organ function.

MIT engineers develop a chip-free, wireless electronic skin to monitor health

Posted by in categories: chemistry, computing, health, wearables

In a significant development, Massachusetts Institute of Technology (MIT) engineers have developed a new category of wireless wearable skin-like sensors for health monitoring that doesn’t require batteries or an internal processor.

The team’s sensor design is a form of electronic skin, or “e-skin” — a flexible, semiconducting film that conforms to the skin like electronic Scotch tape, according to a press release published by MIT.

“If there is any change in the pulse, or chemicals in sweat, or even ultraviolet exposure to skin, all of this activity can change the pattern of surface acoustic waves on the gallium nitride film,” said Yeongin Kim, study’s first author, and a former MIT postdoc scholar.

Making electricity from sweat the key to next wearable tech?

Posted by in categories: biotech/medical, wearables

Imagine a world where the smart watch on your wrist never ran out of charge, because it used your sweat to power itself.

It sounds like science fiction but researchers have figured out how to engineer a bacterial biofilm to be able to produce continuous electricity from perspiration.

They can harvest energy in evaporation and convert it to electricity which could revolutionise wearable electronic devices from personal medical sensors to electronics.

Engineers fabricate a chip-free, wireless, electronic ‘skin’

Posted by in categories: computing, mobile phones, wearables

Wearable sensors are ubiquitous thanks to wireless technology that enables a person’s glucose concentrations, blood pressure, heart rate, and activity levels to be transmitted seamlessly from sensor to smartphone for further analysis.

Most wireless sensors today communicate via embedded Bluetooth chips that are themselves powered by small batteries. But these conventional chips and power sources will likely be too bulky for next-generation sensors, which are taking on smaller, thinner, more flexible forms.

Now MIT engineers have devised a new kind of that communicates wirelessly without requiring onboard chips or batteries. Their design, detailed in the journal Science, opens a path toward chip-free wireless sensors.

New heat-tolerant, high-capacity capacitor created with solid electrolytes borrowed from all-solid-state batteries

Posted by in categories: chemistry, climatology, sustainability, wearables

Capacitors are energy storage devices—consisting of two electrodes and an electrolyte—that are capable of rapid charging and discharging because of charge adsorption and desorption properties at the electrode-electrolyte interface. Because capacitors’ energy storage does not involve chemical reactions, their storage capacity is lower than that of lithium-ion batteries, but they are useful for power leveling for renewable energy that requires repeated charging at high currents, regenerative braking energy for trains and electric or hybrid cars, as well as instantaneous voltage drop compensation devices that prevent equipment failure due to lightning strikes. They are also expected to be used to store energy for wearable devices in the near future.

Most capacitors use a liquid electrolyte with a low boiling point, which can only be used at temperatures below 80℃. Ceramic capacitors that use solid inorganic materials as a dielectric can be used at temperatures above 80℃, but their is much lower than liquid electrolyte capacitors, which limits their use to electronic circuits.

To increase the energy storage of capacitors, it is necessary to have a large contact area at the interface between the electrode and the electrolyte. Making a large contact area is difficult using ; so, the creation of a capacitor with high storage capacity that can also operate at high temperatures has been desired for a long time.
