SMARTCOATINGS - a powerful AlN on metal based energy harvester

MONITORING AND POWERING ELECTRONICS IN REMOTE PLACES WITH A PERFORMING VIBRATION ENERGY HARVESTER

APPLICATIONS

• Fast moving mechanical parts with no possible wiring and/or very harsh environment
• Embedded electronics with difficult access and need for absolute long term reliability  (no failure allowed)

TECHNOLOGY

• Piozelectric layer grown on metal
• Tunable low frequency (5-500 Hz)
• Sturdy (deposited on metal plate)
• Small (typical size 10*50 mm)
• High voltage allowed (>30 volts)
• Powerful (>10 µw/cm², >280 µW/cm3)

BENEFITS

• Long term reliability (years)
• Resisting to 500°C air temperature
• High electrical resistivity (> 108 Ohm.cm)
• Perfect adherence (chemical bonding)
• Thick active layer (5-100 µm) : more power
• Can tolerate damage due to ductile susbtrate
• No lead, no rare materials

PATENTED TECHNOLOGY

=> We are looking for industrial partners to work on vibrational energy harvesting in constraint environments
