Biosensing Devices for Healthcare Utilizing Printing Technology

Abstract

Wearable biosensors that detect physiological indicators in body fluids such as sweat, saliva, and tears are being developed for early detection and prevention of diseases. These devices can be worn in daily life and during exercise to diagnose exercise efficiency and health status, and are useful for health monitoring. In this paper, we review wearable biosensors and biofuel cells based on printing technology, especially screen printing. First, the development of porous carbon materials with controlled nano-/mesopores/macropores as electrode materials were described. Carbon material with controlled pore structure (MgOC) using magnesium oxide as a template is introduced. Next, wearable biosensors and biofuel cells printed with MgOC are described. In particular, sensors for monitoring body fluid components such as glucose in urine and lactate in sweat are introduced.
