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 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.
