I will design PPG sensor PCB, heart-rate monitoring and wearable biometric circuits

Optical biometric products depend on the relationship between the sensor, light source, analog front end, processor, and physical placement. Noise, unsuitable components, and poor power design can make sensor data difficult to interpret. I design PPG and heart-rate monitoring electronics for fitness wearables, activity trackers, biometric prototypes, and connected health devices.

My services include:

PPG sensor and optical module integration

LED driver and photodetector interfaces

Analog front-end and signal conditioning

ADC and MCU integration

BLE telemetry hardware

Battery-powered circuit design

Power filtering and sensor layout planning

Schematic, PCB layout, BOM and Gerber files

I will use your sensor choice, intended measurement, processor, power budget, enclosure, and communication requirements to guide the design. Optical performance also depends on sensor placement, mechanical contact, firmware, and testing; the PCB alone cannot guarantee measurement accuracy.
