Vibration has a serious impact on consumer health. Contacting vibrating tools may cause hand-arm vibration syndrome (HAVS). Therefore designing products that use motors or vibrate while holding should consider this principle. For example the motor part can be separated from the tool itself and connected to it using a cord instead.
