Bee hive texturing of carbon electrode biosensor using screen printing method

Portable biosensing has been widespread through the daily activities of modern human. It enables us to easily deteck a common disease in community such as diabetes trough its glucose level. Currently, the needs to realize a device that able to deteck almost every disease is highly desired. Therefore, research in electrode material in biosensing application is skyrocketed number. Here, a simple method so called silk screen printing is introduced to realize a 3D structure of carbon electrode in order to increase the active surface area. By using two deposition phase of screen layering with specific screen parameter, a repeatable and uniform 3D texture was realized at a thickness around 25µm. Additionaly, the screen printing resolution for line width was at around 1mm with 10% error.
