Your responsibilities

By the end of your internship, you will have designed, built, tested and documented a functional prototype for simple, accurate physical measurements-laying the groundwork for the future automation of laboratory tests and large-scale data acquisition. To achieve this, you will:

1. Understand testing needs and measurement principles: Define measurement requirements, review existing techniques and identify the main constraints involved in future automation.
2. Select and design system components: Choose suitable sensors, actuators and data acquisition systems, and design custom fixtures or mechanical components where needed.
3. Build and optimize the experimental setup: Assemble and integrate the components into a functional prototype, develop test protocols and optimize experimental parameters.
4. Conduct tests and assess performance: Evaluate the reliability, repeatability and reproducibility of measurements, analyze the results and identify opportunities for improvement.
5. Document and communicate your findings: Prepare technical documentation, present your results to relevant stakeholders and recommend next steps toward automation and large-scale data acquisition.
