The proposed mobile charging device addresses the inefficient charging of personal electronics in situations where access to power outlets is unavailable. By harnessing kinetic energy from everyday movements, our design aims to store this energy for immediate charging of mobile devices. The development of a Power Clip, which can attach to various surfaces or apparel, allows users to convert motion into electrical energy efficiently. This solution not only ensures that users can stay connected during critical moments but also champions sustainability through energy scavenging.

Back Story • Imagine that you are in a meeting on the phone and your phone dies with no way to charge it or continue your meeting.
Initial Problem Statement • 3 Words: • Scavenging • Energy • Charge • Problem Statement • Today’s batteries die after prolonged use without a way to quickly charge them on the spot.
Revised Problem Statement • Charging personal electronic mobile devices is inefficient and hard to accomplish without direct access to a power outlet. • Design a product that will harness energy in nature and process that power into a charging system

Where We Are Going • A clip system that can be clipped onto almost any material and can harness kinetic motion energy.
Sketches Power Shirt/Power Glove Power Clip
Power Glove • Takes the movement of fingers to rotate electromagnet creating current. • Current harnessed to charge battery. • Charge pad in the palm to wireless charge mobile device.
Power Suit • The material of the suit is a piezoelectric system designed to harness all movement of the body to a central power location. • Currently not feasible.
Power Clip • Modular design to minimize weight. • Central unit designed to process power to a battery and then to mobile device. • Most feasible.
Requirements • From the survey we have given, we have discovered that the product must have the following requirements, and the nice to haves would come later.
Math and Science Concepts • PE=KE, so KE=mgh for potential vertical motion • Using the walking motion, a magnet can be accelerated up and down changing mechanical to electrical energy (V=I x R (Voltage=Current x Resistance)) • The energy can then be stored in a battery for later use.
Summary • Key Requirement: Charge Mobile Device • Where we are going: Power Clip • Any questions?
