Fabrication

This section details the steps required for fabricating one sensor and how to setup the sensor for measurement. The fabrication of the sensor is mainly a three-step process: casting the conductive rubber (the interface), casting the sensor body and injecting the conductive fluid. 

Overview

Step 1: Conductive Rubber

This step is mainly casting conductive rubber using chopped carbon fiber strands and silicone rubber

Step 2: Sensor Body

This step is casting silicone around the conductive rubber to embed them and provide an interface between the outside and inner cavity of the sensor. Once casted a rubber tube and leads are attached.

Step 3: Sensor Setup

Sensor setup is simply adding conductive fluid to the sensor. In this guide, the conductive fluid is salt water.

Step 4: Equipment Setup

A rough guideline is provided for hardware setup to get readings from the sensor
