Wearable device technology battery innovation is very important -Lithium - Ion Battery Equipment

With the launch of Fitbit in 2009, wearable devices have also become products for mass consumers. At that time, some people questioned whether consumers really have the need to track their walking steps and heat consumption? However, with the continuous development of wearable technology and wearable devices becoming more and more fashionable and intuitive, this industry has developed rapidly.

The global wearable device market is expected to ship more than 126 million units in 2019 (19.6 million units in 2014), and the application of wearable devices is no longer limited to fitness tracking. Next, let's discuss three breakthroughs in this field, which will further promote the revolutionary development of wearable technology.

Battery innovation

If wearable devices are to become as popular as smart phones and tablets, they must use batteries that are thinner, more durable and more flexible. Samsung SDI and LG Chemistry have made significant progress in this area recently. They presented their research results at the 2015 InterBattery Conference held in Seoul.

Samsung unveiled two new batteries. The first one is the ultra-thin flexible battery Stripe with a thickness of only 0.3 mm. Samsung said that this battery has a higher energy density than other batteries on the market because it uses a very small battery sealing space. Due to its lightness and softness, Stripe is likely to realize more types of wearable devices, such as necklaces and clothing.

Samsung also announced another new battery band for accessing the strap of smart watch, which can supply an additional 50% of the power for smart watch. In the durability test, this battery can withstand more than 50000 bends. From this point of view, Samsung does take into account the form and function of new batteries, and believes that these products will overturn the wearable field when they are launched around 2017.(Lithium - Ion Battery Equipment)

LG Chem also announced a new flexible smart watch battery, which has been developed since 2012. The reason why this battery is discussed here is that it can be folded into a radius of 15mm, and its volume is half of that of other batteries on the market. This linear battery will realize a more flexible smart watch design.

Wearable health tattoo

If there is an ultra-thin wearable device that can be pasted on human skin like a tattoo to monitor the vital signs of the wearer, does it sound like a plot of science fiction? In fact, this kind of equipment has appeared several years ago, but their cost has always been high, and it takes a lot of production time. Now a group of researchers from the University of Texas have developed a clipping technology that can produce low-cost ultra-thin health tracking tattoos in 20 minutes.

The process of making this kind of tattoo is to first place the sheared metal sheet on the polymer adhesive, and then print the electronic components on the adhesive. Although this tattoo has not been popularized in the medical field, this latest research breakthrough will make this technology more mature. In the future, doctors will be able to use it to track the vital signs, heart rate, muscle movement and other data of patients.

Nanotechnology wearable device

The study of matter at the atomic and molecular levels can also bring broad prospects for wearable technology. Two years ago, Google X announced that it was developing a magnetic nanoparticles that could detect the presence of cancer cells in the blood and transmit these data to the smart bracelet through optical signals. Earlier this year, Google applied for a patent called Nanoparticle Penetration. It can be seen that Google is gradually achieving this ambitious goal, and the way we detect and treat cancer and other diseases may also be completely changed.

On the other hand, since its discovery in 2003, the magic material graphene (a single-layer carbon atom composed of hexagonal structure, which is the thinnest and strongest artificial material) has appeared 25000 patents. The latest potential application of graphene is in the wearable field. The graphene-coated fiber can detect harmful gases in the air, and then send a warning to the device wearer through LED lights.

Led by researchers from the Korea Institute of Electronic Communications and Jianguo University, this breakthrough research will be applied to industries with serious air quality hazards. Wearable air quality trackers will greatly shorten the response time of employees to threats. Combined with the good cooling performance of graphene, this nano-material is bound to show its skills in the field of wearable technology.
