Vibration Energy Harvester Powers Train Sensors

Trains provide a sustainable source of vibration energy to power sensors, at least while they are moving. Testing has shown that the vibration spectra generated by train wheels was sufficient to allow Perpetuum’s energy harvester to generate 10s of mW of electrical energy – a level sufficient to power sensors to monitor the condition of wheel bearings.

Optimized to deliver the highest power output from vibration frequencies between 30Hz – 60Hz that are typical to the rail industry, Perpetuum’s PMG Rail operates in the temperature range from -40°C to 85°C (-40°F to 185°F) and has factory programmed voltage outputs from 3V – 10V.

Other monitoring and sensing applications for the PMG RAIL products include:

- Bearing Monitoring

- GPS Location Tracking

- Hazardous Cargo Monitoring (Temperature, Pressure, “Door Open”)

- Wheel Condition Monitoring (Flats, Cracks)

- Derailment

- Braking System Monitoring

Energy Harvesting for Sensing Applications Update

If you are interested in the possibility of using energy harvesting
technology to power a wireless sensor network, there are few tools that you should consider to determine if this can make a difference in your next system design.

The 308-page book, Energy Harvesting for Autonomous Systems written by Stephen Beeby and Neil White of the University of Southampton and published by Artech House within the last year and provides chapters on RFID, photovoltaic, kinetic, and thermoelectric
energy harvesting as well as power management, energy storage and a a case study.

At Sensors Expo 2011 in Chicago, the Energy Harvesting
Track on Tuesday and Wednesday provide attendees special insight into the products and their applications from eleven companies.

For those seeking a focused in-depth look at energy
harvesting, the Power Management: Energy Harvesting & Storage Symposium on Monday provides information
from a dozen of the leading energy harvesting companies.

Get Into Energy Harvesting with a Design Kit

All it takes is a sensor to be in the energy harvesting development mode with MicroStrain’s Advanced Pioneer Kit. The kit is based on MicroStrain EH-Link a hybrid energy harvesting wireless sensor node. The node collects energy from multiple sources including strain, vibration, thermal gradients, ambient light and electromagnetic fields. 

The Pioneer Kit includes an EH-Link node, USB Base Station with Antenna, Thermal Electric Generator (TEG), Solar Demo Board, 9-V Alkaline Battery, Battery Clip, EH-Link 1000 ohm Tester Board, and 1000 µF Capacitor as well as Node Commander Software and Manuals CD (Windows® XP, Vista, 7).
