摘要
Example implementations also include a method of sensing the presence and quantity of a biochemical by applying a current across a biochemical sensing electrode and a reference electrode, contacting a hydrogel layer to a biological surface, absorbing a biofluid from the biological surface into the hydrogel layer, obtaining, at a processor coupled to the biochemical sensing electrode and the reference electrode, a change in current across the biochemical sensing electrode and the reference electrode, and generating, at the processor, a quantitative biochemical response. Example implementations further include obtaining a biometric encryption key based on the biological surface, and encrypting the quantitative response based on a biometric encryption key. Example implementations further include contacting a fingerprint scanner to the biological surface, and obtaining a fingerprint pattern from the biological surface at the fingerprint scanner, where the biometric encryption key is based on the fingerprint pattern.
