PREPARING METHOD OF ARTIFICIAL FINGERPRINT BASED ON THE ARTIFICIAL SWEAT

摘要

The present invention relates to a method to manufacture an artificial fingerprint. The method includes: a preparation step of obtaining a digitalized fingerprint shape and an artificial sweat solution including amino acid and inorganic salt; and a printing step of printing the digitalized fingerprint shape on a target material by using a printer applying the artificial sweat solution as ink. The artificial fingerprint is similar to a fingerprint, artificially made by a human, in both quality and quantity aspects while solving the unevenness of an actual fingerprint used for latent fingerprint insufflation research, and therefore, the artificial fingerprint is beneficially used for fingerprint research and education.
