Abstract: The invention relates to a security device (1) comprising at least one authentication device (17) and a locking device (18), which authentication device (17) comprises at least one sensor (2) and an evaluation and comparison module (10), and a communication link (21) exists between the locking device (18) and the authentication device (17), and the sensor (2) is provided in the form of a thin-film sensor for detecting biometric data or spectral properties of the skin and layers of tissue lying underneath, and the communication link (21) is designed to effect a secure, wireless transmission of a unique user code determined by the authentication device (17) and is limited in terms of its operating range to a close-up range, in particular less than 50 cm, and the locking device (18) is deactivated if the user code matches an identification code assigned to the locking device.

Abstract: Described is a fingerprinting device with a translucent top layer (8) which forms a finger rest and between which and a light-emitting layer (9) a layer (1) of light-sensitive elements is provided in a matrix arrangement, and with an evaluation circuit (7) connected to the light-sensitive elements. In order to provide advantageous design conditions, it is proposed that the layer (1) of light-sensitive elements have a translucent, photoactive layer (2) based on organic semiconductors between two translucent electrode layers (3, 4) consisting of intersecting strip conductors (5, 6).

Abstract: Device (1) for optoelectronically characterizing samples by means of electrochemiluminescence (ECL), in which an electric voltage applied across a counter electrode (6) and a working electrode (2) on which the sample spots are disposed excites the sample to luminescence and a reading of the luminescence is taken using an optoelectronic component, characterized in that the optoelectronic component comprises an image detection component (4) with a photoactive layer (10) made from organic semiconductors between two electrode layers (11,14).

Abstract: The invention describes a detection system (1) for analytical separation processes, particularly for electrophoresis, characterized by an optoelectronic sensor layer (5) made from organic semiconductor materials extending along the carrier layer (2) for the sample to be tested, for detecting the separated sample.
