A wearable generator that can charge a mobile phone just by walking appears

While the high functioning is progressing remarkably, a battery cell phone with a strong feeling of being cut off immediately as compared with the old, a technology that will allow you to charge by walking alone has appeared.

With this, you can carry an AC adapter in your bag and carry around, and if you run out of batteries you may walk away searching for available outlets, or you may not need to go to convenience stores to buy dry battery type chargers.

Details are as follows.

According to this release, research by Simon Fraser University in Canada has resulted in developing a lightweight, wearable generator that can charge the battery just by walking.

This generator is attached to the hybrid car by attaching it to the footRegenerative brakeIt will be possible to generate electricity as shown in the figure. If you walk normally, you can generate up to 5 watts of electricity, and if you walk fast you can produce up to 13 watts of electricity. In this case, you can use the mobile phone for 30 minutes by walking for 1 minute.

Incidentally, this technology is considered to be very meaningful not only in charging mobile phones but also in various aspects such as developing countries with poor power situation, medical care, military and so on, so that prototypes can be used within 18 months I want to do it.
