Welcoming "To Use is to Charge!"

What's our green tech concept?

Modern citizen habitually bring along their mobile for communication, iPod for music, tablet for paperwork or even combining all entertainment and work tasks into a single smart phone. However, there is a fatal problem of battery using up very soon after leaving home/office. Users would then be in a trouble of holding a switched off electrical device with none function value.

By current market analysis, people generally bring a supplementary battery out for spare use. Not only heavier and larger than the smart phone itself, it has to be pre-charged. From technological development outlook, wireless charging popularization still takes long. Sockets in home would keep being occupied by our electrical devices and messy charger wires. We have to explore a renewable charging solution to end this demanding electricity consuming cycle.

Our concept "To use is to charge!" is generated from the human behavior. As we found that most people play with their smart phone by using their finger tips most of the time. This action irritates us to think about how to develop a charging device by making use of this mechanical "must" action. The shortage of battery is the serious problem when we use smart phone. After observation, we develop a concept, charging up the smart phone battery when the finger tips pressure adding on smart phone screen. For further mechanical and electrical conduction analysis, we will share with you guys in the coming blogs. 

Who are we?

We are Argon, Jeremy and Claire, a group of three PolyU students with product engineering design background. We can be regarded as Product Designers with Engineering Knowledge while Product Engineers with Design Sense! Therefore, we always aim to improve human's habits and product consuming experience. And now, we are going to be further equipped with PCB design techniques to enrich and realize our technological design. We are all excited about this wonderful event. More to go, see you=)

    You will find that you can't generate anything like enough power to work a mobile phone or tablet computer by harvesting energy from finger pressing. Wind up radios with manually powered generators have been available for some time but they require serious effort to make power. They have experimented with mobile phones and heel powered generators so you might find some information about those on the web.
    There are additional problems with trying to get power from touch screen activity - the very low displacement which is tolerable would require very large forces to make reasonable amounts of power and then you would still need to invent away of converting the flexure of the screen into electricity. Current piezo electric materials are very inefficient when jused for this purpose.
