Embedded Engineer Intern

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 stable 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.
