Pressure-tolerant electronics

Pressure-tolerant electronics (PTE) are electronic components or assemblies that can operate satisfactorily under high pressure (hyperbaric or hydrostatic, such as oil baths), without the need of a high pressure enclosure.{{cite web|last=Barnes|first=Howard|title=A review of Pressure-Tolerant Electronics|url=http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA027967|archive-url=https://web.archive.org/web/20130408132210/http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA027967|url-status=dead|archive-date=April 8, 2013|publisher=US Dept of the Navy}}
