A small, highly portable data-logging system, including a palm-mounted adapter containing an accelerometer and a force sensor, was developed to record user-specific tool-operating times, hand-transmitted vibration, and palm forces throughout all, or a representative part, of an 8-h workday. The microprocessor-based device has proved to be cost-effective, robust, and flexible and can be applied across a wide range of occupations and occupational settings involving exposures to vibration. Relevance to Industry: When considering past research, there still remains a clear need for a methodology that accurately measures day-long vibration exposures over the course of the entire working day regardless of work cycle times and work patterns. The Vibration Exposure Monitor (VEM) system enables hand-arm vibrations to be more accurately characterized and so can assist in modeling exposure-response relationships in vibration-intensive work environments.
