Abstract: The subject invention pertains to multifunctional tendon-mimetic hydrogels constructed from anisotropic assembly of aramid nanofiber composites. The stiff nanofibers and soft polyvinyl alcohol in these anisotropic composite hydrogels (ACHs) mimic the structural interplay between aligned collagen fibers and proteoglycans in tendons. The ACHs uniquely exhibit a high modulus of ˜1.1 GPa, strength of ˜72 MPa, fracture toughness of 7333 J/m2, and many additional characteristics matching those of natural tendons. The surfaces of ACHs can be functionalized with bioactive molecules to present biophysical cues for the modulation of morphology, phenotypes, and other behaviors of attached cells. Moreover, soft bioelectronic components can be integrated on ACHs, enabling in-situ stimulation and sensing of various physiological parameters.

Abstract: A chest and abdomen coupled cardiopulmonary resuscitation device, including a bottom plate and at least two compression/traction mechanisms, wherein each of the two compression/traction mechanisms includes two linear motors with opposite positions, the axes of the two linear motors are perpendicular to the bottom plate, and the bottoms of the linear motors are in slip connection with the bottom plate; and the tops of the two linear motors are fixedly connected by a connecting mechanism, the bottom of the connecting mechanism is fixedly provided with a presser connected to an air pump, and the presser can move on the connecting mechanism along a direction perpendicular to the sliding direction of the linear motors. The device can be adjusted to the optimal compression frequency, depth and duration according to objective physiological indicators, thereby greatly improving success rate of rescue.
