self charging smartwatches

If you are a smartwatch user then you always find one problem with almost every smartwatch that is short battery life. Smartwatches are one of the rapid power drinking gadgets.

We need to continuously charge it up even for a run, and in the busy life of ours, it is hardly possible for us to keep up with the battery life of smartwatches.

That is why self-charging smartwatches are being brought up.

Unlike traditional smartwatches, these self-charging smartwatches do not require frequent charging.

Even this technology is still developing, there are certain smartwatches that have been already available in the market.

What is a Self-charging smartwatch?

Now self-charging smartwatches can be tricky.

There are certain limitations that come with it because generally in a smartwatch there are several sensors and features that have various purposes, and that is the primary source of a smartwatch to have shorter battery life.

So having a self-charging smartwatch, the amount of electrical energy is limited.

Hence, that energy does not meet the amount of energy needed for the sensors and features in a smartwatch. Ultimately, some of the most energy-consuming features have to be omitted out.

However, we have only curetted the self-charging smartwatches that have all the features and sensors that you expect when you choose to buy one.

The technology involved in self-powered smartwatches

Firstly, let’s see about the technology that goes into the self-charging smartwatches to get a clear knowledge about them. Most of the self-charging smartwatches use TEG (thermoelectric generator) that converts heat into energy, solar energy, and kinetic energy.

Thermoelectric generator

The thermoelectric generator is a source of heat energy, but to produce heat as energy, the heat from your body is used to generate electrical energy.

The thermoelectric generator needs 2 parts that are a hot part and a cold part for it to operate. So that the electrical energy is produced during the heat transfer and it is used as the battery life of the smartwatch.

Solar energy

Solar energy is the most basic source of energy, from house electricity to electrical gadgets, etc and in smartwatches, the solar energy is transferred as electrical energy to the watch by specifically made solar panels that can be charged by the exposure of 1 hour at maximum.

Kinetic energy

Kinetic energy is a source of energy that converts mechanical parts to electrical energy, this process can be made to the electrically-operated machine in the case of a smartwatch the mechanical parts presented in the watch are used as a source of energy and stored in a battery reservoir.
