Batteries are now one of the biggest limitations in the advancement of wearables technology. While wearables are still evolving, when people try to make wearables stand out longer or are lighter in design, these improvements cannot be implemented due to battery limitations.
If you want to keep the wearable device market growing, how to improve battery utilization and improve the source of power is the most important problem to solve. As wearables continue to evolve, we need batteries that are thinner, more efficient, and last longer. Battery size, shape, power reserve, and reliability are all key factors to consider when manufacturing wearable devices. Here are some alternative solutions that can replace traditional batteries:
lithium battery
The most common lithium battery is the button battery that is commonly used in life. The CR2032 type button battery can be seen everywhere, you can buy it at the pharmacy, from the calculator to the heart rate detection belt. Of course, there is a smaller button battery CR1225, which is generally used in hearing aids. The power of these button-type lithium batteries decreases with size, and most of the button-type lithium batteries are disposable, so they can only be used in small devices such as hearing aids, remote control keys, light switches, and doorbells. Button batteries are also used in some of the earliest wearable devices. Button-type lithium batteries will continue to be used in wearable devices, and easy replacement is an important feature.
Thin film lithium battery
Thin-film lithium batteries also use lithium battery technology similar to button batteries, which are commonly used in smartphones or handheld devices because thin-film batteries can be charged multiple times and their shapes can be better adapted to various device. Because the size of the battery determines the battery's power, this thin film battery will take up more space than the button battery. Thin film batteries are more suitable for use in flat-panel wearable devices because the shape of these devices matches the shape of the battery, or they can be installed into furniture or walls to achieve remote control of these devices. .
Bag lithium battery
The bag battery packs the lithium battery in a plastic bag or a nylon bag. The battery can be used in a variety of shapes and thicknesses, making it easy to use in almost all small devices, even on mobile phones. Battery. However, there is also a drawback in the bag type battery, that is, sometimes the gas will accumulate in the battery bag, so that the battery bag may expand and rupture. If you want to use this battery in your equipment, you need to have enough space to meet its expansion needs and reduce the risk of battery bag explosion.
Graphene battery
Graphene battery is a kind of battery based on two-dimensional carbon material. Its appearance has excited the material science community. The use of graphene battery in the future may become a trend. Among all types of batteries, graphene batteries have the highest energy density and the strongest electrical energy reserve. Today, graphene batteries are not widely used in practice because they are much more expensive than other types of batteries. Graphene battery technology needs further development and maturity, we can continue to pay attention to graphene battery technology in the next few years.
Super capacitor
Supercapacitors have very little power leakage compared to ordinary batteries, and have very high power storage capacity. Depending on the device used, the supercapacitor can be used as a primary source of energy for the device or as a supplement to conventional batteries. They can be quite small in size, but they can store more than 1 Farad. If the battery can be charged, its charging time will be much shorter than that of a conventional rechargeable battery.
Multi-channel access to energy
In the past few years, a large number of various forms of energy harvesting for rechargeable batteries have emerged, which can be converted into a wide range of electrical energy sources, including kinetic energy (motion, vibration, rotation), thermal energy, piezoelectricity and even radio waves. (You can think of it as recycling energy wirelessly). The air pressure monitoring device embedded in the tire first used a rechargeable battery that relies on kinetic energy, and the kinetic energy battery can work as long as the vehicle does not remain in a non-driving state for a long time. However, if you apply a kinetic energy battery to a wearable device, you need to consider another situation. Many wearable devices are left idle after being bought for a few days. In this case, the kinetic energy battery is difficult to play. effect.
Wearable device manufacturing calls for battery innovation
As the number of wearable devices continues to increase, the demand for wearable devices is smaller, longer battery life, remote control, and more intelligent. The implementation of these devices requires high-performance and high-capacity batteries. For support. If we can't continue to improve the battery, then the wearable device industry will not be able to continue.
24 hours mechanical timer
Instant indicator
Min.setting time:15 minutes. Max.setting timer:24 hours
With hand switch,can be switched to operating and
setting at any time
Instructions:
1. Set program: 1 pin is equivalent to 15 minutes. Determine desired start time and push down pins until desired
off time.
For instance, if you want electrical devices to work from 8:00am to 11:00am and from 13:00pm to 17:00pm, you
just need to put down allthe pins between the three period time.
2. Set the current time: Turning the dial clockwise until the arrow pointing to
current time.
For example,if now it is 8:00 am, please turn the dial and make sure the
arrow point to 8. (See the picture.)
3. Plug the electrical device directly into the timer. Make sure the electrical
device is power-on.
4. Plug the timer into electrical outlet and the electrical device will be work
according to the setting program.
Note: = Normal Ope n = Timing
Make sure the switch on the Timing position. If it
is on the [Normal Open" mode, the electrical device is
always power-on and the timer function no work.
