Fuji Prescale mylar tactile pressure-indicating sensor film reveals surface pressure magnitude and distribution between contacting or impacting surfaces. When placed between the surfaces, it permanently changes color directly proportional to the amount of pressure applied. Following testing, the control can be archived for future comparisons. The flexible film is 4 to 8 mils thick and may be hand or laser cut to fit.
