Wireless monitoring in intensive care units by a 3D-printed system with embedded electronic

In this paper, the design, realization, and preliminary testing of a portable wireless system for measuring key metabolites (e.g., glucose, lactate, calcium, potassium) in intensive care monitoring is presented. The system consists of a 3D-Printed case, which includes the fluidic system that drives the monitored human fluids on top of the sensing devices. The case fully integrates a hardware platform on PCB (Printed Circuit Board) that connects the biosensors to the read-out font-end and to a Bluetooth^® module for the data transmission to a mobile Android interface. Two metabolites, glucose and lactate, that are important to monitor in critical patients, were measured in the range of clinical interest.
