Breadboard Proof of Concept
• Used a Linear Regulator which is less then 50% efficient
• Used a Hand Crank motor• Used a 3.4V Battery
PCB Board Design
PCB Product Ready to Be Ordered
Top Bottom
Electrical Energy Harvesting Overview• Battery = Average 80% Efficiency• Buck-Boost = Average 85% Efficiency• Motors = 2.7W each = 5.4W at 30RPM• 3.456 W generation at 30RPM• 691.2 mA generation at 5V, at 30RPM
Benefits to design• Easily can covert to AC Motor if Needed.• PCB Fits on top of the Buck-Boost Regulator
therefore saving space.• Battery can be charged by a wall charger too.• Arduino boards and other electronics can also be
power by battery therefore opening up further applications and not limiting it to phone charging.
