Hand-arm vibration syndrome has been an occupational hazard for a long time. However, a detail understanding of its vibration exposure inset is not yet available, largely because instrumentation for its in situ monitoring has been difficult to implement. With the development of wearable electronics, new solutions for its monitoring and study have become possible. This work studies the usefulness of monitoring vibration magnitude, EMG (electromyography) signal, PPG (photoplethysmogram) signal and finger skin temperature in quantifying continuous hand-arm vibration exposure. A commercial orbital sander was used. The results show that vibration magnitude and median frequency of EMG signal do not lead to better measurements than finger skin temperature and PPG signal for such monitoring. The finger skin temperature decreases 8.8% on average during 25 minutes of vibration exposure and increases 6.2% on average during 15 minutes of rest. The pulsatile component of PPG signal decreases 4.8% and increases 35% on average during vibration and rest, respectively. The non-pulsatile component of PPG signal decreases 28% and increases 5% on average during vibration and rest, respectively. Finger skin temperature and PPG signal can be effective indicators in HAV monitoring but have to be treated carefully.
