About this project

Spring Assist Piezo Generator

Objective: Develop a spring-assisted piezoelectric generator for small-scale energy harvesting.

Context: In India, decentralized and renewable energy solutions are crucial for powering devices in remote or off-grid areas. Piezoelectric generators offer a way to convert mechanical motion into usable electrical energy for low-power applications.

What you'll build: You'll design and assemble a mechanical frame with springs and piezo sensors, integrating a bridge rectifier and capacitor to store harvested energy. The system will be calibrated for optimal piezo positioning and tested for power output, with the final device demonstrated by powering an LED or charging a battery. Mechanical and electrical integration will be key focus areas.

Deliverables: A working prototype of the piezo generator, test results, and a demonstration video or live demo.

Milestones

1. Design of mechanical and electrical assembly

10 marks 6d

Submit detailed CAD drawings and circuit schematics for the spring assist piezo generator, including all mechanical components, piezo placement, and electrical connections. Ensure all parts are dimensioned and annotated, and the assembly sequence is clear. Assessment focuses on completeness, clarity, and integration of mechanical and electrical systems.

2. Piezo positioning and calibration

10 marks 6d

Document the exact placement of piezo elements within the assembly and describe your calibration procedure, including applied force and resulting voltage measurements. Provide data and photos showing calibration steps. 'Done' means clear evidence of optimal positioning and repeatable calibration results.

3. Power output testing

10 marks 6d

Present measured power output data from your assembled generator under various loading conditions. Include graphs or tables showing voltage, current, and calculated power for each test. Assessment checks for accurate measurements, proper test setup, and clear analysis of generator performance.

4. Enclosure fabrication

10 marks 6d

Submit photos and a brief build log of your fabricated enclosure, showing how it houses and protects the generator and electronics. Highlight material choices, assembly steps, and any features for accessibility or durability. 'Done' means the enclosure is functional, fits all components, and meets safety requirements.

5. Demonstration with load (LED or battery)

10 marks 6d

Provide a video and written summary demonstrating the generator powering an LED or charging a battery. Show the load connected, generator operation, and measurable output. Assessment focuses on successful load operation, clear documentation, and evidence of practical energy generation.
