Frequently Asked Questions

What are the power requirements for wearable applications?

Goertek components for wearables feature ultra-low power consumption: MEMS microphones consume 150-200μA, accelerometers use 6.5μA active and 0.5μA sleep, pressure sensors use 2.7μA. This enables year-long battery life in fitness trackers. Contact BeiLuo FAE team for power optimization guidance.

Ultra-low power enables long battery life.

How do I achieve waterproofing in wearables?

For waterproof wearables: 1) Use waterproof speakers (SPK series) with IPX7 rating

2) Seal all enclosure joints with gaskets

3) Use waterproof buttons and connectors

4) Apply conformal coating to PCBA

5) Design proper pressure equalization vents. Contact BeiLuo FAE team for waterproof design guidance.

Use IPX7 rated components and proper sealing.

What sensors are needed for a fitness tracker?

A typical fitness tracker includes: 1) Accelerometer (SPA2032) for step counting and activity detection

2) Pressure sensor (SPL06-007) for altitude and floor tracking

3) Optional gyroscope for advanced motion tracking. These sensors provide comprehensive activity and health monitoring. Contact BeiLuo FAE team for fitness tracker design guidance.

Accelerometer and pressure sensor for basic fitness tracking.

How do I implement haptic feedback in wearables?

For haptic feedback: 1) Select linear vibration motor (SPM-VIB series) for crisp feedback

2) Use dedicated haptic driver IC for precise control

3) Mount motor securely to case for best feel

4) Implement varied vibration patterns for different notifications

5) Optimize power consumption with appropriate drive waveforms. Contact BeiLuo FAE team for haptic design guidance.

Use LRA motor with haptic driver for best feedback.

What is the smallest package size available?

Goertek offers industry-leading compact packages: accelerometers in 2.0mm x 2.0mm, pressure sensors in 2.0mm x 2.5mm, MEMS microphones in 2.75mm x 1.85mm, and vibration motors in 8mm x 3.0mm. These ultra-compact sizes enable integration in the smallest wearable devices. Contact BeiLuo FAE team for component selection guidance.

2mm x 2mm sensors available for ultra-compact designs.
