Design and characterisation of energy harvesting systems

Access Description
Access to lab with different measurement devices, generators and power management test-kits and platforms to design and characterize energy harvesting systems
Technical Offering
  • Measurement and recording of power output of energy harvesting systems (like solar cells, thermoelectric generators, vibration harvesters)
  • Design and implementation of energy harvesting systems
  • Samples and materials of different harvesters available
  • Power management test-kits available
Main Equipment
  • Tira electrodynamic shaker S 52110
  • dSPACE DS1104 R&D controller board
  • Autolab PGSTAT302N and FRA32M module: Impedance spectroscopy in the range of 10 µn;Hz – 1 MHz
  • Existing scripts to obtain 3D plots of the characterized harvester
  • Agilent DC Power Analyzer N6705A
  • Laser sensor for exact amplitude measurement of mechanical harvester
  • Thermographic camera VarioCAM high resolution (640×480 pixel, accuracy of ± 1.5 K)
  • Digital resistor board
  • Heating plate
Typical applications
  • Development of specific harvesting systems with available building blocks like TEGs, solar modules, voltage converters and storage devices.
  • Design and characterization of single harvesters (thermal or vibration) and also of AC-DC and DC-DC converters in conjunction with their EH generators (vibrational or thermoelectric).
Case Study
A test set-up including the electrodynamic shaker S 52110 from Tira with a dSPACE DS1104 R&D controller board, a digital resistor and a Simulink software is available. This software enables a characterization of vibration energy harvester by means of its generated power as a function of the resistance and frequency for a given amplitude: It is also possible to apply real acceleration data to the electrodynamic shaker for further characterization.
