Outline of Final Research Achievements

In the present study, I introduce two paper-based wearable biofuel cells fabricated by screen-printing technique. One is used as a self-powered diaper sensor. The biofuel cell can generate electric power from glucose in urine. The maximum output power increase along with increase of glucose concentration. Thus, we can monitor the glucose concentration by measuring the maximum output power. The paper-based biofuel cell exhibited a maximum power density of 0.7 mW in 100 mM glucose solution. Our group also developed an adhesive bandage-type biofuel cell, which get a power from lactate in sweat. In the present study, we discuss the characteristics of the wearable biofuel cells in detail.
