Abstract Piezoelectric, pyroelectric, and ferroelectric materials are considered unique biomedical due to their dielectric crystals asymmetric centers that allow them directly convert various primary forms of energy in the environment, such as sunlight, mechanical energy, thermal into secondary electricity chemical energy. These possess exceptional conversion ability excellent catalytic properties, which have led widespread usage within fields. Numerous applications demonstrated great potential with these materials, including disease treatment, biosensors, tissue engineering. For example, piezoelectric used stimulate cell growth bone regeneration, while pyroelectric applied skin cancer detection imaging. Ferroelectric even found use neural implants record electrical activity brain. This paper reviews relationship between ferroelectric, piezoelectric, effects fundamental principles different reactions. It also highlights preparation methods three significant progress made applications. The review concludes by presenting key challenges future prospects for efficient catalysts based on nanomaterials

Muscle atrophy resulting from peripheral nerve injury (PNI) poses a threat to patient's mobility and sensitivity. However, an effective method inhibit muscle following PNI remains elusive. Drawing inspiration the sea cucumber, we have integrated microneedles (MNs) microchannel technology into guidance conduits (NGCs) develop bionic microneedle NGCs (MNGCs) that emulate structure piezoelectric function of cucumbers. Morphologically, MNGCs feature outer surface with outward-pointing needle tips capable applying electrical stimulation denervated muscles. Simultaneously, interior contains microchannels designed guide migration Schwann cells (SCs). Physiologically, incorporation conductive reduced graphene oxide zinc nanoparticles polycaprolactone scaffold enhances conductivity properties, facilitating SCs' migration, myelin regeneration, axon growth, restoration neuromuscular function. These combined effects ultimately lead inhibition Consequently, concept synergistic effect inhibiting promoting regeneration has capacity transform traditional approach repair find broad applications in repair.
