Hardware / Embedded Systems Intern

Duration:Total: 3 Months (Unpaid)

- A certificate will be provided after internship completion.
- Work Nature: In-person (Office)
- Location: IIT Madras Campus, Guindy, Chennai.
- Project OverviewGoal: Evaluate photoplethysmography (PPG) for cuffless blood pressure (BP) tracking.
- Target: Early preeclampsia risk detection in pregnant women.
- Current Focus: Sensor stability, clean signal acquisition, and edge-case testing in healthy adults.

Key ResponsibilitiesFirmware Development: Program microcontrollers to stream high-frequency raw PPG and 3-axis accelerometer data.
- Data Jitter Control: Ensure highly reliable sampling rates and eliminate packet transmission lag.
- Time Synchronization: Align raw sensor signals with timestamped reference cuff blood pressure readings.
- Signal Quality Testing:



Collect pilot data under physical edge cases (e.g., motion, induced vasoconstriction).
- Storage Formats: Structure and log collected biosignals into clean binary, HDF5, or Parquet files.
- Required Skills

Core Tech: Embedded C/C++, Microcontrollers (ARM Cortex, ESP32, or similar).
- Communication: SPI, I2C, UART, and high-speed USB/Serial communication.
- Data Parsing: Python (for logging, synchronization scripts, and data serialization).
- Sensor Integration: Experience interfacing with optical biosensors (PPG) and inertial units (IMU).
- Instrumentation: Familiarity using oscilloscopes, logic analyzers, and basic hardware debugging tools.
