A portable sweat urea sensing system is a promising solution to satisfy the booming requirement of kidney function tele‐monitoring. However, the complicated manufacturing route and the cumbersome electrochemical testing system still need to be improved to develop the urea point‐of‐care testing (POCT) and tele‐monitoring devices. Here, a universal technical route based on a high‐throughput automatic laser printing strategy for fabricating the portable integrated urea monitoring system is proposed. This integrated system includes a high‐performance laser‐printed urea sensing electrode, a planar three‐electrode system, and a self‐developed wireless mini‐electrochemical workstation. A precursor donor layer is activated by laser scribing and in situ transferred into functional nanoparticles for the drop‐on‐demand printing of the urea sensing electrode. The obtained electrodes show high sensitivity, low detection limit, fast response time, high selectivity, good average recovery, and long‐term stability for urea sensing. Additionally, a laser‐induced graphene circuit‐based miniature planar three‐electrode system and a wireless mini‐electrochemical workstation are designed for sensing data collection and transmitting, achieving real‐time urea POCT and tele‐monitoring. This scalable method provides a universal solution for high‐throughput and ultra‐fast fabrication of urea‐sensing electrodes. The portable integrated urea monitoring system is a competitive option to achieve cost‐effective POCT and tele‐monitoring for kidney function.

“…Firstly, using screen#4 a Ag paste (ESL) was printed and followed by oven drying at 150 o C for 15 min. The resulting layers were then fired in a conveyor belt furnace for 45 min with peak temperature of 800 o C. To form an Ag/AgCl layer, the Ag layer was then dip coated in 0.05 M FeCl 3 for 50 s, and then cleaned in a DI water [13]. Formation of the KCl electrolyte layer was done by manually applying 3.5 M KCl solution (gel) covering the entire reference, counter, and working electrodes of the device.…”

A Dissolved Oxygen (DO) sensor has been designed and fabricated on an 8.5 x 22.5 mm Alumina substrate using thick film technology. The structure of the sensor device consisted of AgPd working/counter electrode, Ag/AgCl reference electrode, RuO2active layer, KCl electrolyte, and TiO2membrane. Formation of the Ag/AgCl reference electrode was done by chlorination of Ag layer using FeCl3, and the TiO2membrane was formed by screen printing of TiO2paste. Measurement was done to study the sensor’s performance based from the current-voltage characteristics between 1.1 – 1.6 V. The results showed that a stable diffusion current was obtained when the input voltage was 1.4 V, resulting in the best sensor performance with a sensitivity of 0.560 μA l/mg and a stable step response time of 4 min. The device showed highly potential to be used as candidate for online water quality monitoring system.
