My Invention

Self-charging smart phones

"stress-free phone"

(Original Problem & Idea / Solution)

    As you have probably felt, charging a smartphone takes a lot of time and electricity. And even during use, you have to worry about how much charge is left, which is stressful.

    My invention, which I call the "Stress Free Phone," can be used very comfortably because it does not need to be recharged.

(Specifics)

・This smartphone is equipped with a variety of energy collection systems. For example, solar panels could be integrated into the back or technology that converts body heat and movement into electrical power. This would allow the smartphone to automatically recharge during daily use or even in standby mode, allowing the user to use the smartphone without worrying about running out of battery power.

・This smartphone has a solar panel by default. The price at this time is 100,000 yen. It will cost 20,000 yen to increase the number of solar panels, but this will increase the efficiency of self-charging.

・Solar-wearable smartphones are equipped with a body temperature sensor. It measures body temperature and converts that thermal energy into electricity to charge the battery. The body temperature sensor is made of skin-friendly material to provide a comfortable fit.

(Summary)

Automatic rechargeable smartphones are environmentally friendly, using clean energy such as sunlight and body heat. It also eliminates the stress people have felt about running out of charge or having to recharge.

Considering the price of electricity and charging cords, the result would be cheaper.
