MAHLE Thermoelektronik GmbH, CRA 2.4, Janina Paris, 27-September-2019
Three main aspects have to be considered:
1. Mechanical connection:What are the installation space conditions?
2. Thermal design:What are the thermal conditions?
3. Electrical configuration:What are the power requirements of the application?

What can I expect from a motion basedEnergy Harvesting system?
PIEZO-MAGNETIC µ-GENERATOR SMART POWER MANAGEMENT
• SPEED INDEPENDENT ENERGY GENERATION
• VERY LOW COUNTER TORQUE
• ROTATION OR TRANSLATION EFFICIENT
• SMART ENERGY MANAGEMENT ALGORITHMS
• DEDICATED STORAGE ROUTINE
• LOW POWER SENSORS MANAGEMENT
5 PATENTS 6 PATENTSØ 25mm / h 5mm
100 µJ every 90°rotation whatever the speed!1 – 10 mW power range
ABILITY TO POWER ANY KIND OF DEVICES: SENSORS, RADIO, ACTUATORS…
Technology Assets
Power generated vs Air flow:Piezo-Magnetic & Motor
Piezo Magnetic:-Starts at Low Air Flows-Generates higher power for Low Air Flows
Technology comparison:
Cost
Piezo Magnetic:-Lasts longer than a motor-Easier than battery replacement
Coin cell -> every 2 months
Shaft -> every 3 years
Energy Harvesting system development steps

potential difference
Electrical model:-Current generator or
else?
:Do you need to store? Will you overproduce?
Use case definition is key
Electrical model:-Current generator or
else?
Significant impact, can represent>50% of the power generated
How to size its motion basedEnery Harvesting system?
Identify the use case and application1
2 Do you need energy source to be stable and available continuously ?
3 What would the electrical model of the harvester should look like? - Current generator- Voltage generator
4 Define your power management strategy- Consume constantly all the energy provided- Consume on demand which implies local storage/buffer
5 Implement and test
Criticity?Lifetime?Cost of Ownership? (vs batteries including maintenance)
- Impact energy storage strategy
- High Voltage – Low Current ?- Mid voltage – Higher current ?
- Lifetime and reliability testing are KEY !!!!
