Abstract

Vibrations are a well known potential cause of health diseases and therefore constitute a main concernfor the safety of workers in a large number of activities. In order to prevent health hazards, national andinternational institutions have issued laws and directives which establish recommended limits to theworkers’ exposure to vibrations during operations. Consequently, if the amount of adsorbed vibrationexceeds the allowable daily limits the worker has to stop his job. Recent wireless sensing and communicatingtechnologies can effectively be employed for such purpose, allowing to develop monitoring customizeddevices at affordable cost which could be easily employed during the workers’ activity. Insuch context, the present research proposes an innovative system aimed at estimating the hand–armexposure to vibration according to the Standard EN ISO 5349-1:2004. In particular the proposed systemis based on Micro Electro-Mechanical Systems (MEMS) technology and involves the design of a compactwearable unit to be attached to the waist of the operator and a fixed station for data storage and analysis.The paper reports the design of such a system and an experimental test performed on hand held shakerscommonly employed for olive harvesting. The results highlight the opportunities offered by these emergingtechnologies in developing intelligent devices to be included in the worker’s equipment which mightsignificantly modify the current approach to safety management in the next future.
