Smart watches that do not require charging. How many are there?
The battery life is one of the most criticized parameters of modern smart watches. And each manufacturer is chosen differently to solve the problem. Recently, there are more and more options when the clock should work forever, “feeding on” heat, the sun,
holy spirit , kinetic energy, etc. We have collected some of the most vivid examples, concepts, prototypes and working gadgets in this collection.
the cost of which is $ 299 3r3191. . The uninterruptible power supply for them is solar energy, which is collected in an integrated panel.
The watch supports two time zones, analyzes physical activity and receives notifications, which are displayed on the display as diode signals. Works in tandem with a smartphone.
According to the developer, an hour of stay in natural light or a few hours in artificial light is enough to provide a continuous supply of energy. In this case, of course, we must remember that the clock display should not be hidden by the sleeves of clothing!
The amount of energy collected is available in the mobile application.
3r3182. SEQUENT - kinetic energy [/b]
This is perhaps one of the most promising projects, which is
so far. under development . Preorder can be issued on Indiegogo (Kickstarter already a fair amount of money raised). The cost of "early" - $ 400.
The watch promises an eternal power reserve, the energy for which will be provided by kinetic energy: you move - the watch is charging.
In this case, the model will be able to support such sensors as the heart rate monitor and GPS, which are quite energy-intensive.
Steps, calories, notifications - wherever without them. Looks like something fantastic.
3r3182. Frederique Constant - “the newest solar panels” [/b]
At the moment - this is more of a concept, not even a prototype, and Frederique Constant is in the subtitle rather for attracting attention.
The fact is that the technology works. partner of the brand who participated in the development of smart watches for the company earlier. The talk is still about hybrid watches, in which the “newest” solar panel will be integrated, which in one hour will accumulate so much energy that it is enough to count steps and receive notifications.
In general - it looks like LunaR.
3r3182. Matrix PowerWatch X - thermoelectric element 3r3183.
3r33180. Matrix PowerWatch
- already a serial copy that you can buy. The watch comes in three versions: two models are “watch-pedometers”, model X is a smart watch with the ability to receive notifications.
At the heart of the work Seebeck effect, opened in 1821. The bottom line is that a thermocouple of different materials with a temperature difference is capable of producing a certain amount of energy, which can be enough for anything: in this case, the work of a pedometer, a sleep tracker, notifications and a digital clock. Yes, unlike all models from the list - Matrix - digital models.
The heating element in this context will be your wrist in contact with the back of the case. The external “cooler” will be the external environment. The charge index and temperature difference will be displayed. In an especially hot climate, the clock may not charge, but in this case, the accumulated energy is enough - up to one year of autonomous work.
3r33170. With the new firmware version, PowerWatch X got a localized display. 3r3171.
3r3176. 3r33177. We have a coupon [/b] 3r3179. At 3r3-380. model X
until the end of October there is a 10% discount - HBRX .
Matrix is not the first to experiment with this method of charging gadgets. One of the earliest cases is the model. Bulova Thermatron .
In 198? the watches turned out to be too expensive, and the model practically did not remember the market, so that after almost 20 years Seiko was shown the Thermic model, which was based on the same principle of power, everything went as if in a new way.
The viability of this model was tried to be confirmed in Citizen by the Eco-Drive Thermo model.
However, in each of these cases we are not talking about smart watches: these are the usual “switch” models without any additional functions for their owners.
