With the increase of the TENG\u2019s tribo-interface roughness and the molecular weight of the PLLA, the power output of TENG was greatly increased owing to more charges being produced and the excellent mechanical properties PLLA possessed. When the 317 L SS plate surface roughness was 66.54% measured by the image J software and the PLLA film with a larger molecular weight at 500 000 was patterned with the 1000 mesh screen template, the maximal short current, open voltage and transferred charge of TENG reached up to 60\n                    <jats:italic>\u03bc<\/jats:italic>\n                    A, 150 V and \u223c125 nC, respectively. At the optimum condition, the maximum instantaneous power of the TENG was 5.5 mW at a load resistance of \u223c2.5 M\u03a9 and the saturation voltage was 20 V when the load capacitance was 0.1\n                    <jats:italic>\u03bc<\/jats:italic>\n                    F. The evaluation of the TENG\u2019s biocompatibility\n                    <jats:italic>in vitro<\/jats:italic>\n                    was performed by using the simulated body fluid (SBF) solution and ultrasonic wave to mimic the body environment with various vibrations, respectively. After 6 h ultrasonic bath for the directly immersed TENG, the pH of the SBF solution just changed slightly from 7.4 to 7.61 with an acceptable degradation of the output power of TENG. The cellular toxicity test also demonstrates that the mouse L929 cells grow excellently with normal morphology even after 5 d. These results indicate that the TENG has a good stability in the body environment and the output performance can still drive many micro-medical devices.\n                  <\/jats:p>","DOI":"10.1088\/1361-6528\/aab280","type":"journal-article","created":{"date-parts":[[2018,2,27]],"date-time":"2018-02-27T07:45:23Z","timestamp":1519717523000},"page":"205402","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Fabrication, characterization and\n                    <i>in vitro<\/i>\n                    evaluation of triboelectric nanogenerator based on 317 L stainless steel and polylactic acid"],"prefix":"10.1088","volume":"29","author":[{"given":"Wei","family":"Li","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoxue","family":"Xu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenjiang","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yun","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4490-8550","authenticated-orcid":false,"given":"Minfang","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2018,3,19]]},"reference":[{"key":"nanoaab280bib1","doi-asserted-by":"publisher","DOI":"10.1002\/aenm.201600665","type":"journal-article","article-title":"Triboelectric nanogenerators driven self\u2010powered electrochemical processes for energy and environmental science","volume":"6","author":"Cao","year":"2016","journal-title":"Adv.
