Abstract :

Electrode substrates such as silicon or glass have been commonly used in chemical and biosensor. However, these substrates have limited application used in biomedical field, especially when dealing with soft tissue in our body. Gelatin, which extensively used in the biomedical field, is biodegradable with excellent biocompatibility.The purpose of this study was to extend the application of gelatin into micro electro mechanical system (MEMS). Gelatin with electride was produced by screen printing technique, followed by analysizing the substrate surface smoothness, swelling property and the adhesion between the ink and substrate. The results showed that the swelling ratio could be controlled by the cross-linking reagent. The scotch tape test showed that the adhesion strength of the silver inks was better than carbon ink. Moreover, the outcome of cyclic voltammetry showed that the eletric transmission of silver electrode was much faster than the carbon electrode. In this study, we have successfully prepared the gelatin film with the electrode using either carbon or silver inks. The circuit pattern could be flawlessly printed on to the substrate, and silver electrode showed better adhesion on the surface of gelatin film. Gelatin may become a promising electrode substrate to be used as biosensor as well as electrical stimulation for myocardial tissue engineering.
