To mitigate the risks of accidental battery ingestion, legislation has been introduced to regulate the locking of battery compartments. Regulation of battery housings has translated into modest reductions in the number of battery ingestion cases reported. We report here the fabrication of waterproof, pressure-sensitive battery coatings that are nonconductive in the low-pressure gastrointestinal tract, yet conduct in higher-pressure standard battery housings. These safer batteries are expected to reduce complications from accidental battery ingestion.<\/jats:p>","DOI":"10.1073\/pnas.1418423111","type":"journal-article","created":{"date-parts":[[2014,11,4]],"date-time":"2014-11-04T03:14:46Z","timestamp":1415070886000},"page":"16490-16495","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":40,"title":["Simple battery armor to protect against gastrointestinal injury from accidental ingestion"],"prefix":"10.1073","volume":"111","author":[{"given":"Bryan","family":"Laulicht","sequence":"first","affiliation":[{"name":"Division of Biomedical Engineering, Department of Medicine, Center for Regenerative Therapeutics, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115;"},{"name":"Harvard\u2013MIT Division of Health Sciences and Technology, Massachusetts Institute of Technology, Cambridge, MA 02139;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Traverso","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Massachusetts General Hospital, Harvard Medical School, Boston, MA 02114;"},{"name":"Department of Chemical Engineering and Koch Institute for Integrative Cancer Research, Massachusetts Institute of Technology, Cambridge, MA 02139;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vikram","family":"Deshpande","sequence":"additional","affiliation":[{"name":"Department of Pathology, Massachusetts General Hospital, Harvard Medical School, Boston, MA 02114; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Langer","sequence":"additional","affiliation":[{"name":"Harvard\u2013MIT Division of Health Sciences and Technology, Massachusetts Institute of Technology, Cambridge, MA 02139;"},{"name":"Department of Chemical Engineering and Koch Institute for Integrative Cancer Research, Massachusetts Institute of Technology, Cambridge, MA 02139;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey M.","family":"Karp","sequence":"additional","affiliation":[{"name":"Division of Biomedical Engineering, Department of Medicine, Center for Regenerative Therapeutics, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115;"},{"name":"Harvard\u2013MIT Division of Health Sciences and Technology, Massachusetts Institute of Technology, Cambridge, MA 02139;"},{"name":"Harvard Stem Cell Institute, Cambridge, MA 02138"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2014,11,3]]},"reference":[{"key":"e_1_3_3_1_2","first-page":"661","article-title":"Injuries from batteries among children aged <13 years\u2014United States, 1995-2010","volume":"61","author":"Centers for Disease Control and Prevention (CDC)","year":"2012","unstructured":"; Centers for Disease Control and Prevention (CDC), Injuries from batteries among children aged <13 years\u2014United States, 1995-2010.
