From mind-reading headsets to shape shifting robots. In this video, I will be covering 3 of the craziest technologies that exist today. So without further ado, let’s jump right in.
1. Mind-Reading headsets
First off we have mind-reading headsets. Essentially, they are a type of wearable technology that can allow you to communicate with computers without even uttering a word. This is the promise of the AlterEgo.
This device created by engineers at MIT uses subvocalisation to convert your inner monologue to digital commands. If you didn’t know every time you are processing a thought larynx and jaw are moving which is known as subvocalisation.
These movements can then be detected by the headset and subsequently converted into different actions, all the user has to do is think the word for the action they want to perform.
In preliminary testing they managed to navigate a TV menu, check the time and even cheat at playing chess.
2. Smart Dust
Smart Dust is a new state of art technology that is comprised of tiny sensors that are as small as a grain of sand.
The concept of smart dust has been around for decades, it was first devised in 1992 for military applications and in 1997 there was the first proposal to build a wireless sensor node that had a volume of just one cubic millimeter in diameter.
The idea of smart dust is to employ tiny sensors that can detect and transmit data on various parameters such as pollution levels, traffic patterns, and weather conditions. The potential applications of this technology is endless.
For example, these miniature sensors could be dispersed by the wind to collect more precise data on weather patterns, while also being utilized in agriculture to provide real-time information on crop nutrition and hydration needs.
Smart dust can also be embedded in concrete to evaluate the structural soundness of buildings. Pretty nuts to think about.
Ultimately, smart dust can fit in small spaces that were traditionally inaccessible while remaining virtually invisible. They have there own power supply whilst also having wireless capabilities that can relay information on temperature, toxins and vibrations to name a few.
Although this technology was proposed a couple decades ago it has only recently become a reality. In 2016 the University of Berkeley built the first dust sized sensor that can be implanted in the body to monitor peoples health.
It can detect nerves, muscles and organs in real time and uses ultrasound for communication. It also has the potential to stimulate muscles and the immune system.
3. Shape-Shifting Robots
You are probably thinking that shape shifting robots is a far fetched idea, but you will be wrong. This is exactly what scientists at the university of Pittsburgh have created.
A robot that can change their shape to adapt to different environments. In this case the robot is moving between the bars of it’s prison. Essentially, the robot is composed of the metal gallium which low melting point of about 29 degrees Celsius.
This metal has infused with magnetic particles which can then be controlled by scientiests using magnets. This allows them to prompt movements and decide when it melts or stretches.
By alternating the magnetic field the temperature of the robot is increased allowing it to melt to the point that it can crawl through tight spaces. Then through ambient cooling it can regain its solid state.
