Innovative Approaches to High-Resolution and Flexible Stretchable Sensors
In a recent study, researchers successfully navigated the challenges of achieving both high spatial resolution and flexibility in stretchable sensors by creating two novel sensor designs: an EIT-based system and a grid-based system. The EIT system effectively utilized boundary electrodes to generate high-resolution strain maps via impedance tomography, while the grid system streamlined data acquisition but necessitated advanced multiplexing to reduce crosstalk.
The Sciospec ISX-3 EIT system played a crucial role in this research, providing a robust platform for acquiring the necessary high-quality impedance measurements that underpinned both approaches.
