Definitions
- Known microwave sensors contain, for example, a rectifier diode and a light-emitting diode.
- the lead electrodes of the diode (diode legs) act as microwave antennas.
- the object of the invention is to enable the detection of microwaves in a wider field of application, in particular the possibility of integrating such a detection into clothing, wearable electronics and cell phones.
- a device detects electromagnetic radiation, in particular invisible electromagnetic radiation, high-frequency radiation and / or microwave radiation, that is to say electromagnetic radiation which is not light, preferably also not infrared or ultraviolet light.
- the device has an organic diode with which the radiation is detected.
- An organic diode is understood to mean in particular a diode with an organic semiconductor material.
- the electrodes of the diode can be made of organic material, but do not have to be.
- Organic diodes can be made using thin-film technology and thus mechanically flexible.
- the device can be a flexible, inexpensive thin-film element for the detection of radiation, which can be easily integrated into any surface.
- the organic semiconductor of the organic diode and / or the electrodes of the organic diode can be implemented using thin-film technology.
- the organic diode is in particular one
- Rectifier diode that rectifies the absorbed radiation power.
- the electrodes of the organic diode preferably serve as antennas for the radiation to be detected.
- the device can also have a display element that indicates when radiation is detected.
- the organic diode with which the radiation is detected can also serve as the display element at the same time.
- the detection it also has the function of a light-emitting diode.
- invisible electromagnetic radiation in particular high-frequency radiation and / or
- Microwave radiation detected by an organic diode.
- Advantageous refinements of the method result analogously to the advantageous refinements of the device.
- 1 shows a device for the detection of electromagnetic radiation with an organic diode.
- the diode 1 shows a device for the detection of electromagnetic radiation in the form of an organic diode 1, 2, 3 with an organic semiconductor 1 and two electrodes 2, 3, preferably implemented as metal electrodes, which are laterally extended to form antennas.
- the diode is designed such that it functions simultaneously as a rectifier diode for rectifying the electromagnetic radiation received from the electrodes extended to form antennas and as a light-emitting diode for optically displaying this radiation.
- the organic semiconductor 1 is implemented in the form of a semiconductor stack, that is to say it consists of a plurality of, in the present case two organic layers, a charge carrier injection layer and a light-emitting layer. In individual cases, the semiconductor stack is made up of up to eight layers.
- the device can be implemented as a microwave sensor, possibly also as a microwave display device, in thin-film geometry with the help of one or more organic diodes.
- Organic diodes and light emitting diodes can perform all three functions.
- Organic diodes are manufactured in sandwich geometry, with an organic semiconductor being embedded between two electrodes. These electrodes can also be used as microwave antennas ( ⁇ / 2 dipoles). The absorbed microwave power is rectified by the diode. The received microwave power is displayed by feeding the voltage into a light-emitting diode.
- the functionalities of the device can be generated by combining different organic individual elements.
- the sensor consists only of an antenna and a rectifier diode.
- a light-emitting diode or a light-emitting diode array is also added for the display element.
- the antenna can be designed separately and connected to the diode, or it can be designed directly as a supply path to the diode.
- the rectifier function and the display function (lights) can be achieved by one and the same element in the form of a diode or by the combination of two or more individual diodes.
- the antennas can be designed as metal strips or as printed highly conductive polymer layers.
- the display element can be designed flexibly on foils or on rigid substrates.
- the display element can also be designed semi-transparent and can therefore be easily in all Integrate surfaces, for example in cell phones, in clothing, in the glass of microwave ovens etc.
- the sensitivity can be adjusted by the layout of the antennas, the efficiency of the display elements or the area of the display elements.
- the electro-optical, microwave-indicating component is used for the optical signaling of incident microwave power. It is characterized by a very simple and therefore inexpensive construction. It preferably consists of a rectifying organic light-emitting diode, the electrodes of which serve as antennas for the power consumption.
- the sensor can be used as a power meter by suitably connecting differently sensitive sensors. Light-emitting diodes of different colors can also be used in this context.
