The presentation will discuss describe the development of textile- and tattoo-based flexible biofuel cells and batteries. We will illustrate the favorable electrochemical behavior of these wearable devices, and demonstrate the ability to generate substantial levels of electrical power from the human perspiration in a non-invasive and continuous fashion. Mechanical stress studies indicate that the printed devices survive large mechanical deformations. Technical challenges and prospects for using textile- and tattoo-based electrochemical biofuel cells and batteries will be discussed, along with several demonstrations and prospects for future on-body applications.
