For mobile data acquisition, the alcohol, temperature, UV, and NH3 were detected by monitoring the resistance changes under specific voltages with a source meter module, consisting of a dc/ac generator, an output buffer, and a multiplexer. Humidity was detected by capacitance measurement with the source meter module. The differential pulse voltammetry module was used for UA and CAF monitoring, and chronoamperometry was used for glucose monitoring. Electrophysiological signals were recorded by the physiological potentiometric module consisting of the programmable gain amplifier and digital filter. The signals were smoothed by a low-pass filter and converted by the analog-to-digital converter for further processing in the digital signal processor. The processed data were transmitted to the smartphone wirelessly by Bluetooth Low Energy. The mobile data acquisition circuit was connected to LSM-based wearable devices using the flexible flat cable (Premo-Flex, Molex) and the Z-axis conductive tape (Adafruit).
