At low fan speed, a speed increaser may be needed. Generator cogging torque and mechanical resistance can increase fan loading; development focuses on a low-cogging PCB generator and a low-loss transmission.

Goals: battery-free sensor power and compact integration. Sensor examples: temperature, humidity, vibration, air quality and filter condition. Output and the impact on fan loading require validation.
