In this work the brocade method is presented and used to determine mechanical properties of biological materials. Young modulus and Poisson ratio have been determined for frozen faba bean. Microscopy images of randomly deposited markers on samples surface have been transfered to computer memory. Then changes in marker positions were analysed. The method is precise and can be applied also for wet materials. Moreover the method is not affected by any side effects present in the sample close to attachments. Results obtained for fresh, frozen and dried faba bean have been compared. Young modulus and Poisson ratio were very close for frozen and fresh faba bean samples
