• Converts mechanical vibration to electrical energy
• Stored for later use using energy harvesting boards with advanced thin-film batteries or ultra-capacitors
• Used for wireless sensors, traditionally battery-powered applications o Examples: lighting control, smart utility metering o Replace or extend the life of batteries
• Select technical specifications o Size = 12.5 x 10.8 x 10.0 mm o Peak power output = 100 µW o Open circuit voltage (AC) = 14 V o Standard frequency = 120 Hz o Weight < 5g
• Microscale technology is o Functional at lower frequency, smaller, lighter
Product - Piezoelectric Energy Harvesters

Industry Value Chain
• Wireless sensors can be used in various industries, eg: automotive, industrial, civil infrastructure, consumer electronics
• Regardless of the ultimate application, sensors need power and must communicate with other components (controller/hub/gateway/other sensors in network)
• Part of the telecommunications industry • Exclusively in design, agreement with large electronics foundry for manufacturing

PVC Diagram • Depend on manufacturing
partner X-FAB • Device uses Aluminum
Nitride, so access to raw materials is a risk
• Product part of a larger system, i.e. wireless sensor, so revenue strongly coupled to customer’s revenue
• Need marketing, sales channels
• Good networks with TI, Eastman Kodak, Cornell
• Skilled in MEMS research and design

Investability Diagram • Cons
o Market dominated by large battery suppliers
o Design infrastructure built around batteries and their output; competitors/customers wary of disruptive changes
o MEMS still a young industry (~1990) – unproven, risks
o Many Univs engaged in similar research, not that specialized
o Kionix – comparable exit proxy, gyroscope MEMS § 1st investment in 2002 § Sold in 2009 for $233 million § Investors did not hit target IRR
• Pros o MicroGen devices last 20 years whereas
standard batteries last 1-3 years, opening new sales opportunities for MicroGen

• Continue to bootstrap company for several years
• Needs several years of showing sales with the $4.3 million they have now to see if any market potential
• Downside to not investing in company now is that may have a missed opportunity to get in early, but learn from Kionix example
