Soft Microtubular Sensors for Biomedical Applications
We developed a flexible, stretchable, wearable, and washable piezoresistive microtubular sensor that is highly sensitive to mechanical perturbations. Its tiny footprint is approximately a cross-section of a strand of hair, which is one of the smallest in the existing technologies. This enables users to apply the sensor almost indistinguishably, thereby improving compliance and comfort. Furthermore, the tubular structure allows conformability over 3D curvatures, which cannot be achieved with planar substrates.
