The invention relates to a fingerprint recognition module comprising a substrate consisting of a material that is electrically insulating at least on its upper side and at least partially thermally insulating. Said substrate receives a composite of structured thin films on its surface, which directly forms a measuring field on the surface of the substrate for measuring a fingerprint. Said composite consists of an array of resistive, temperature-dependent elements, and contains strip conductors which connect the resistive, temperature-dependent elements to at least one connection field located on the substrate, outside the measuring field, and form part of the composite of structured thin films. The substrate also contains at least one microelectronic switching circuit which is electrically connected to the at least one connection field and contains the switching circuits by which means the thin film structures are controlled in order to heat the resistive, temperature-sensitive elements, the resistive, temperature-sensitive elements are read out, and the data is retransmitted.

A process is provided for the intracellular manipulation of a biological cell () which is positioned adhering to a support area () in a culture medium (). Inside the support area () for the cell () an opening into the membrane of the cell () is created spaced from its support edge. The edge of the cell membrane surrounding the opening, adhering to the support area (), thus seals off the cell fluid situated in the interior of the cell () from the culture medium () and insulates the cell fluid against the culture medium (). The interior of the cell () is manipulated through the opening. An apparatus for implementing the process is also provided, including an object carrier () with a support area () for adhering the cell and a poration tool () for creating the opening in the cell membrane. The poration tool () may be any of various chemical, mechanical and/or electrical devices.

The invention relates to a method for producing a sensor (), wherein a carrier chip () is produced. Said chip is provided with a sensor structure () comprising an active sensor surface (). A material () capable of flowing is applied onto carrier chips () in such a way that the sensor structure () has a thinner layer thickness on said active sensor surface () than on the area of the carrier chip () which borders on the active sensor surface (). The material () which is capable of flowing is hardened thereafter. The hardened material () is subsequently removed by chemical means from the surface which faces said carrier chip () until the active sensor surface of the sensor structure is layed bare.

The invention relates to a method for producing an optical transmitting and receiving device () comprising a light emitting transmission element () and a receiving element () which converts this light into an electrical magnitude. The transmission and receiving elements are inserted into a silicon substrate. The optical transmitting and receiving device () is preferably inserted in a monolithic manner into a common substrate, comprising a sequence of superimposed layers for the light emitting transmission element () and the light receiving element (). An electrically insulating intermediate layer () is incorporated between the transmission and receiving element.
