Wearable technology is getting more and more popular now, and we all want to see what happens next. In the field of wearable devices, in addition to smart watches, motion trackers and smart clothing, there have been more cutting-edge Innovative Technology.
In the next year, five years or even ten years, we will see more new wearable device technologies appear in front of us, and we will further shed our dependence on smartphones between the wrist and the cloud. Create more connections.
No need to charge
Flexible and flexible sensors are the most important thing for smart clothing products, but don't forget that it is very interesting to charge these devices in addition to sewing these sensors into your clothes. StretchSense from New Zealand has released a flexible sensor with energy harvesting capabilities. When bent, this special sensor generates and stores energy to power the electronic device.
One of the most direct applications of this type of sensor is clearly in the field of wearable devices. Built into the body of motion trackers and fitness wristbands, this sensor can extract energy from the natural movements generated when the device is working, thus completely solving the problem of weaker endurance of such devices.
In addition, Korean scientists have developed a sensor with high conductivity, so if smart clothing is developed in the future, this technology will be the key to success.
Detecting toxic gases
We often talk about how wearable devices detect our physical indicators, but have you ever thought that they can help protect us from the surrounding environment?
Researchers from MIT have developed a wearable sensor that can be used to detect traces of toxic gases in the air. The chemical sensor weighs only one piece of paper and uses a circuit of carbon nanotubes, and the team coats the surface of the carbon nanotube with a polymer called a supramolecular polymer. Induction material. When exposed to toxic gases, the chemical bonds of the supramolecular polymer are partially destroyed; and when the surface coating of the supramolecular polymer is destroyed, the conductivity of the carbon nanotubes is greatly increased. Finally, the sensor's signal is transmitted to a cell phone or other wireless device, allowing the cell phone or wireless device to read the presence of toxic gases in the air in a matter of seconds.
At present, this technology is not only suitable for soldiers on the battlefield, but also has great development potential in the medical field in the future.
Ultrasensitive nanosensor
There is now an ultra-sensitive nano-scale sensor that can even track the frictional vibrations of the male spider's abdomen, which is also of great significance in the field of wearable devices.
Scientists at Seoul National University invented the nanosensor system. The unique feature of the whole system is that the gap between the sensors is up to the nanometer level, which ensures high sensing sensitivity. Specifically, the researchers added a 20-nanometer platinum layer to the viscoelastic polymer surface to build a sensor frame. By extending the surface of the platinum variant, a gap is created between the upper and lower layers, exposing the underlying polymer, and the researchers measured the conductivity of the sensor surface.
In the future, this technology can be used on wearable devices. In addition to detecting heart rate changes, it can also help people with disabilities who have language or hearing impairments to have the perceptual power of "Spider-Man".
Graphene is everywhere
This amazing material is a hexagon made up of a single layer of carbon atoms, and researchers hope it will be the best material for displays, batteries and even biomimetic implants. It is flexible, transparent, but more durable than steel, and also facilitates the transfer of charge.
This application in the field of bionics can also be applied to the health tracking field in the future. For example, researchers at Imperial College London use it in synthetic skin and are expected to create artificial skin with high sensitivity. There is also a graphene sweat detection sensor like SweatSmart that monitors the body's hydration during exercise.
In addition, Samsung has produced a lot of conductive materials made of graphene in recent years, and is expected to double the life of the battery.
Low power technology
The current life time of wearable device products varies from one day to half a year, which is why Intel will play a very important role in the field of wearable devices in the future.
Intel's Curie module is based on Intel's first dedicated system chip for wearables, which integrates low-power Bluetooth communication and motion sensors for a button-sized solution. Whether it's computing, motion sensing, Bluetooth low energy and battery charging, the integration of modular integrated components allows developers to develop wearable devices with longer battery life, from rings, bags, bracelets, Pendants, fitness trackers and buttons can be easily developed by developers.
At the New York Fashion Week in the United States, we have already seen the special clothing for the Winter Extreme Games with the Curie module.

Amorphous Iron Core For Peak Suppressor
Anyang Kayo amorphous Technology Co.,
Ltd., founded in 2011 with a registered capital of RMB 5 million that is
a technology-based manufacture. We specialize in the production of
nano&amorphous iron core and amorphous&Nano Ribbon, CT, electric
component(including comon mode choke coil, Filter Inductance, high
frequency transformer,etc.).Our
main products are amorphous and nanocrystalline iron cores which are
widely used in communication, house appliances, electric power,
automobile, new energy and other fields.
Our company's peak suppressor amorphous beads have a very large inductance when the current is zero, which can effectively block the reverse reset current generated by the diode. This material can be saturated at a very small current that can be widely used to the switching power,frequency converter and so on.
