Flexible Electrode Capacitive Sensors System for Human Fluid Detection

The maturity of capacitive sensing technology is explored to implement a fluid detection system based on easyto-manufacture flexible electrode sensors and a reading circuit based on an 8-bit microcontroller. The construction of the electrodes made with adhesive copper tapes, the reading circuit with the EFM8SB1 device from Silicon Labs© embedded with a capacitive reading peripheral, and the post processing made with software developed in Python. All these elements presented are easily found on the market, thus forming a quick and inexpensive system to build.
