We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

A direction‐aware piezo‐transmittance strain sensor is realized through the engineered alignment of carbon nanotubes. This anisotropic architecture instantaneously modulates optical transmittance, achieving ultra‐high sensitivity and exceptionally low hysteresis. By effectively eliminating signal crosstalk to precisely decouple multidirectional strains,

Multifunctional Adhesive Hydrogel for Rapid Cardiac Hemostasis and Antibacterial Protection
A multifunctional polyacrylamide/gelatin/tannic acid hydrogel (PGT) is presented for rapid cardiac hemostasis under wet, dynamic conditions. Surface tannic acid coating enables instantaneous wet adhesion, accelerates coagulation, and confers antibacterial activity within a single platform.

A strain‐activated mechanical metamaterial is developed to achieve programmable dual‐phase stiffness through an intrinsic geometric locking mechanism. Finite element modeling and parametric analysis identify the key design parameters governing activation strain, stiffness transition, and energy absorption.
