In this review, we summarize the current evidence supporting the potential benefits of electric stimulation (ES) in the physiology of peripheral nerve repair (PNR). Moreover, we discuss the potential of piezoelectric materials in this context. The use of these materials has deserved great attention, as the movement of the body or of the external environment can be used to power internally the electrical properties of devices used for providing ES or acting as sensory receptors in artificial skin (e-skin). The fact that organic materials sustain spontaneous degradation inside the body means their piezoelectric effect is limited in duration. In the case of PNR, this is not necessarily problematic, as ES is only required during the regeneration period. Arguably, piezoelectric materials have the potential to revolutionize PNR with new biomedical devices that range from scaffolds and nerve-guiding conduits to sensory or efferent components of e-skin. However, much remains to be learned regarding piezoelectric materials, their use in manufacturing of biomedical devices, and their sterilization process, to fine-tune their safe, effective, and predictable in vivo application.<\/jats:p>","DOI":"10.3390\/biomedicines11123195","type":"journal-article","created":{"date-parts":[[2023,12,1]],"date-time":"2023-12-01T03:58:02Z","timestamp":1701403082000},"page":"3195","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Review of Piezoelectrical Materials Potentially Useful for Peripheral Nerve Repair"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5537-9340","authenticated-orcid":false,"given":"Diogo","family":"Casal","sequence":"first","affiliation":[{"name":"Departamento de Anatomia, NOVA Medical School|Faculdade de Ci\u00eancias M\u00e9dicas (NMS|FCM), Universidade NOVA de Lisboa, 1169-056 Lisboa, Portugal"},{"name":"Plastic and Reconstructive Surgery Department and Burn Unit, Centro Hospitalar Universit\u00e1rio de Lisboa Central, Rua Jos\u00e9 Ant\u00f3nio Serrano, 1169-045 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0893-0686","authenticated-orcid":false,"given":"Maria","family":"Casimiro","sequence":"additional","affiliation":[{"name":"Centro de Ci\u00eancias e Tecnologias Nucleares (C2TN), Instituto Superior T\u00e9cnico (IST), Universidade de Lisboa, 2695-066 Bobadela, Portugal"}]},{"given":"Lu\u00eds","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Departamento de Engenharia e Ci\u00eancias Nucleares (DECN), Instituto Superior T\u00e9cnico (IST), Universidade de Lisboa, 2695-066 Bobadela, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1235-0107","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Leal","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica Estrutural (CQE), Institute of Molecular Sciences (IMS), Instituto Superior T\u00e9cnico (IST), Universidade de Lisboa, 2695-066 Bobadela, Portugal"}]},{"given":"Gabriela","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Centro de Ecologia, Evolu\u00e7\u00e3o e Altera\u00e7\u00f5es Ambientais (cE3c) & CHANGE\u2014Global Change and Sustainability Institute, Departamento de Biologia Animal, Faculdade de Ci\u00eancias, Universidade de Lisboa (FCUL), 1749-016 Lisboa, Portugal"}]},{"given":"Raquel","family":"Lopes","sequence":"additional","affiliation":[{"name":"Gynaecology and Obstetrics Department, Maternidade Alfredo da Costa, Centro Hospitalar Universit\u00e1rio de Lisboa Central, R.
