Energy Harvesting

• What is it?
• Macro scale- wind and solar
• Micro scale- electromagnetic and piezoelectricity

• [3]

• [2]

Piezoelectricity

• Deform to get voltage

• Apply voltage to deform

• [4]

• [5]

Piezoelectricity

• What is it?
• Occurs in polycrystalline materials
• (For example: Quartz, lead-zirconate-titanate, Rochelle salt, etc.)

Piezoelectricity- Output

• Output always different
• High voltage, low current
• Sample output:
