The power needs of industrial wireless sensors present obstacles to adoption for some Wireless Sensor Networks (WSN) deployments, forcing users to limit duty cycles or incur the expense of repeated battery maintenance. Perpetua builds solutions to harvest thermoelectric energy for wireless sensors from commonly available industrial heat source, including steam pipes, pumps, water heaters, fuel tanks, furnace ducts, compressors, motors, ovens, smelters.
WSN applications/markets today are led by Oil and Gas exploration and production, Refineries, Power and Utilities, and Chemicals with a many others contributing to a lesser extent.
With a strong return-on-investment resulting from battery maintenance cost reductions and the additional benefit of providing redundant power to monitoring critical process variables, the applicability of Perpetua’s products parallel the wireless sensors they power. Deployments to date have mirrored the general adoption of WSN with the exception that Perpetua Energy Harvesters have been restricted to Ordinary Locations. In Q2 2104 Intrinsically Safe certifications for Power Pucks will be in place allowing their use in virtually all hazardous environments.
Through joint development
agreements, contracts and grants from numerous commercial companies and federal
agencies, Perpetua is developing on-body energy harvesting technology
for personal wireless computing, sensing and other mobile devices.
Perpetua has branded this exciting new wearable energy harvesting
Continuously powered by always-available
body heat energy, wireless sensors can transmit vital physiological
information for emergency first responders, athletes, soldiers,
medical patients, and general wellness monitoring. Applications
for body heat-to- electric energy include:
• Wireless Personal Location Devices
• Medical / Fitness Monitoring
• Defense Applications / Personal Protection
• Ultra Low-Power Mobile Consumer Electronics
• Always available power source can replace or greatly extend
the life of batteries
• Highest native voltage thermoelectric technology
• Unique manufacturing flexible thin-film technology
offers a more robust solution that can stand up to pressures of
molding and other package integration
