Smart roller: normal and three-axis stress measurement sensor array for automated fiber placement
Soft capacitive sensors offer an approach for enhancing real-time measurements of both normal and shear stresses. We have created a ‘smart’ roller. It is a cylindrical capacitive sensor array designed for automated fiber placement (AFP) machines, widely used in laying down carbon fibers to create composite parts for aerospace and automotive applications. Available in two variants, the smart roller accommodates distinct measurement needs: one model features 4 × 13 sensing units for normal stress, while the other employs 4 × 7 sensing units for three-axis stress measurement. Both variants incorporate Bluetooth Low Energy (BLE) technology for wireless data transmission.
