The expanding field of cardiac and skeletal muscle tissue engineering demands efficient solutions to study the biology of the tissues and model disorders. In this study the Cuore system is presented, employing optical fiber sensors and light interferometry to detect 3D Tissue Engineered Skeletal Muscle contractions. Thanks to nano-Newton resolution force measurements and integrated electrical pulse stimulation, contractility of hiPSC-derived tissues is evaluated. Additionally, its efficacy in assessing drug responses, like caffeine and clenbuterol, showcases its potential in studying contractile tissue biology.

A femtosecond laser direct writing method is proposed for CLCP microstructure construction and light-driven CLCP micromirror preparation. Effects of structure length-width ratio, cutting direction, light irradiation time, and light intensity on bending and twisting behaviors are investigated. The micromirror system can achieve not only a swing but also a rotation of the mirror surface.

Ultrasonic-assisted freeze-drying is used to prepare Polyimide/CNTs aerogel flexible piezoresistive sensors. Ultrasonic can not only control the growth of ice crystals but also optimize the powder dispersion to a certain extent. The prepared composite aerogel sensor can maintain stable sensing ability at room temperature, high temperature, or even after high temperature aging.

Piezoresistive sensor yarns with a twisted-yarn structure comprising carbon-coated covering fibers and metallic core fibers are proposed to detect external forces. The elastic deformation of the covering yarns results in resistance changes. Sensor-implemented fabrics are demonstrated to detect biological motions such as respiratory and finger movements.

Azo Molecular Glass Submicron Pillar Array is explored to map the polarization morphology of vector light field, which is recorded by directional pillar deformations in the transverse plane and read out by SEM and AFM. The optical effects produced by the pillar deformations are also investigated for vector beam characterization and structural color surface development.
