A shifting paradigm from the traditional computing systems is the emulation of the brain computational efficiency at the hardware-based level, a field that is also known as neuromorphic computing. Although neuromorphic computing with inorganic materials has been advanced over the past years, nevertheless biological plausibility is questionable in many cases of solid-state technologies. In the brain, for instance, neural populations are immersed in a common electrolyte or cerebrospinal fluid and this fact equips the brain with more efficient features in processing when compared to electronic devices or circuits. Due to this topology in biological neural networks, higher order phenomena exist such as global regulation of neural activity and communication between different regions in the brain mediated by the presence of the global electrolyte. In this work, device concepts will be presented that lead to biological plausibility in organic neuromorphic devices, including global phenomena and synchronization functions. Introducing this level of biological plausibility, paves the way for new concepts of neuromorphic communication between different subunits in a circuit.","PeriodicalId":189694,"journal":{"name":"Organic and Hybrid Sensors and Bioelectronics XII","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115979772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, while the solution‐based active layer materials employed in these types of systems have been studied quite intensely, the conducting structures that feature in printed circuits, RFID applications, logic systems and electrodes in optoelectronic devices have not received as much attention. \u0000Inkjet-printing in particular, as an additive, upscalable, direct write technique that requires no masks or lithographic pre-patterning of substrates, has been utilized to produce such structures in a wide variety of (opto)electronics, paving the way to fully solution-processed devices. However, for full compatibility with flexible, low cost substrates, the processing conditions of the deposited structures need to be controlled.\u0000This contribution highlights our work on utilizing inkjet-printing to deposit copper nanoparticles (CuNPs) in order to form conducting structures within a range of electronic applications, specifically optoelectronic devices and printed circuits, and discusses methods to improve the conductive and interfacial properties. A reductive sintering approach is presented as an alternative to commonly used laser or flash lamp curing techniques. \u0000The findings presented address the importance of continuing work in improving the effectiveness of printed conductive structures, including in their use in organic and hybrid (opto)electronic devices, in order to move towards fully solution-processed and flexible electronics.","PeriodicalId":189694,"journal":{"name":"Organic and Hybrid Sensors and Bioelectronics XII","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127746745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a body area network is reported including organic sensor nodes, recording relevant health status parameters, and implantable actuators for delivery of pharmaceuticals. These are then included within electronic skin patches also comprising body-coupled communication protocols that transmit and receive information, via capacitive coupling, that is transported through the body. In a parallel communication pathway, sensor and actuator information is also collected into a Bluetooth-based unit for further transfer to cloud computing. While in the cloud, deep learning improve the sensor-to-actuator decision-making. Our complete system is the first in its kind, based on organic and Si-chip technology, performing sensory-regulated delivery of pharmaceuticals, supported by cloud connectivity and machine learning.","PeriodicalId":189694,"journal":{"name":"Organic and Hybrid Sensors and Bioelectronics XII","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131914658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

[1-6] In this context, polycrystalline bis-(triisopropylsilylethynyl)pentacene (TIPS-pentacene) was printed onto polyethylene naphthalate (PEN) substrates patterned with parylene-C dielectric, PEDOT electrodes and gold pads to form fully organic flexible x-ray detectors. The electrodes were patterned using orthogonal photolithography and oxygen reactive ion etching to define a width/length (W/L) = 100 µm/10 µm. An organic voltage divider built using these materials was hot bar bonded to a printed circuit board (PCB) via a flexible conducting tape to form a complete sensor system. The devices were irradiated with a variety of localized and large area sources and the output was extracted from the node between the two resistors and then connected to an operational amplifier via a second PCB. Dark currents for each resistor were in the 100 pA - 1 nA range. The device demonstrated has the potential to be applied in microdosimetry to allow for detection using a cross-section that matches organic tissue forming a solid state tissue equivalent detector (SSTED) [7].\u0000References:\u0000[1] Beckerle, P. and Strobele, H., 2000.
