The organic thin-film light-emitting device includes a substrate, a plurality of first electrodes arranged parallel on the substrate, an electroluminescent layer made of an organic material and formed on the first electrodes, a plurality of second electrodes formed on the electroluminescent layer, and an electrically insulating barrier wall. The tissue penetration device may optionally include sampling and analyzing functions, which may be integrated. The solid lubricant is at least one of hexagonal boron nitride, graphite, calcium fluoride, lithium fluoride, magnesium fluoride, barium fluoride, tungsten disulfide and molybdenum disulfide particles. In addition, there is also provided a data receiver search method using such an electronic device network system. An enforcement device driver and an enforcement monitor on a mobile device use the enforcement policy to control access to resources associated with the mobile device regardless of whether the mobile device is \u201conline\u201d and connected to a network or \u201coffline\u201d and disconnected from a network. Roller contacts and pogo pin contacts fall within the scope of the invention.
