Abstract
The present invention relates to devices that include a mechanochromatic material (10) which changes color according to a pressure exerted on the device. As a result, the mechanochromatic material (10) functions as an indicator of pressure exerted on the device. A user can view the mechanochromatic material (10) to determine whether the pressure exerted on the device exceeds a threshold pressure, whereat a color change will occur in the mechanochromatic material (10).
