This work describes the low-cost fabrication of waterproof electronic decals (WPEDs): highly conformable disposable biosensors capable of monitoring sweat and vaginal pH. WPEDs contain a polyaniline/silver microflakes sensing layer optimized for accurate impedance-based pH quantification across the clinically relevant range of variation of most biofluids. WPEDs also contain a heating layer that serves to both stimulate sweating and prevent saturation of the sensing area, reducing the variability of the measurements. The conformability of WPEDs enables their simple and allergy-free attachment to skin, where they can monitor sweat pH, or to the surface of paper-based sample containers, for the pH-based diagnosis of bacterial vaginosis. WPEDs are mostly transparent, self-adhesive, breathable, flexible, moisture-insensitive, and able to maintain their accuracy under significant mechanical and thermal stresses. A cost-effective wearable and portable impedance analyzer wirelessly transmits pH data in real-time to the smartphone of the user, where a custom-developed App enables long term monitoring and telemedicine applications. Our results demonstrate the feasibility of using inexpensive single-use WPEDs and a reusable, wireless impedance analyzer to provide a wearable solution for the real-time monitoring of sweat pH and the accurate at-home diagnosis of bacterial vaginosis, improving the capabilities of current low-cost, point-of-care diagnostic tests.", "copyright" : "All rights reserved", "file" : "Biosensors and Bioelectronics - 2020 - Conformal, waterproof electronic decals for wireless monitoring of sweat and - Pal.pdf:C\\:\\\\Users\\\\ac143615\\\\Nextcloud\\\\Zotero database\\\\Biosensors and Bioelectronics - 2020 - Conformal, waterproof electronic decals for wireless monitoring of sweat and - Pal.pdf:application/pdf;Biosensors and Bioelectronics - 2020 - Conformal, waterproof electronic decals for wireless monitoring of sweat and - Pal.pdf:C\\:\\\\Users\\\\ac143615\\\\Nextcloud\\\\Zotero database\\\\Biosensors and Bioelectronics - 2020 - Conformal, waterproof electronic decals for wireless monitoring of sweat and - Pal2.pdf:application/pdf", "issn" : "09565663", "doi" : "10.1016/j.bios.2020.112206", "bibtexKey": "Pal2020ConformalWaterproofElectronic" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2f0eaee139b62c81c5ac0af6c06edebb7/ifu", "tags" : [ "imported","PH","DB","ML" ], "intraHash" : "f0eaee139b62c81c5ac0af6c06edebb7", "interHash" : "674377d28ff94570b30225006af67914", "label" : "Plate Roll Embossing Process - The Efficient and Flexible Embossing of Sheet Metals", "user" : "ifu", "description" : "", "date" : "2024-07-30 13:24:23", "changeDate" : "2024-07-30 13:24:23", "count" : 1, "pub-type": "inproceedings", "booktitle": "Proceedings of the 14th International Conference on the Technology of Plasticity - Current Trends in the Technology of Plasticity","series": "Lecture Notes in Mechanical Engineering","publisher":"Springer Nature Switzerland","address":"Cham", "year": "2024", "url": "https://doi.org/10.1007/978-3-031-40920-2_9", "author": [ "David Briesenick","Mathias Liewald","Pascal Heinzelmann" ], "authors": [ {"first" : "David", "last" : "Briesenick"}, {"first" : "Mathias", "last" : "Liewald"}, {"first" : "Pascal", "last" : "Heinzelmann"} ], "editor": [ "Katia Mocellin","Pierre-Olivier Bouchard","Régis Bigot","Tudor Balan" ], "editors": [ {"first" : "Katia", "last" : "Mocellin"}, {"first" : "Pierre-Olivier", "last" : "Bouchard"}, {"first" : "Régis", "last" : "Bigot"}, {"first" : "Tudor", "last" : "Balan"} ], "pages": "78--89","abstract": "Embossings on sheet metal surfaces allow a targeted enhancement of local part strength and affect thinning in deep drawing. However, conventional manufacturing of tailor embossed blanks on press machines with simultaneous intrusion of embossing punches results in high force demands and tool wear. Incremental forming of each indentation reduces the embossing forces required but increases cycle time. Embossing by rolling provides limited flexibility in embossing patterns. Therefore, presented paper deals with the development of a new approach for an efficient and flexible embossing of sheet metals -- the Plate Roll Embossing Process (PRE Process). Here, a modular design of an upper and lower tool is used, into which various embossing, counter punch or blank positioning inserts can be integrated. The sheet metal is placed between the tools and the setup is moved through a defined roll gap of a mill stand. The line contact between rolls and tool defines a relatively small forming zone, which is moved translationally through the workpiece by the rotation of the rolls. Numerical and experimental investigations were performed with aluminium AA6014 and steel DC01, showing homogenous embossing results with reduced loads compared to conventional embossing. Furthermore, the paper demonstrates that the high flexibility of the tool and process design enables embossing of flat workpieces as well as the simultaneous embossing and forming of curved parts. Finally, tensile tests performed with embossed specimens show that the PRE Process represents a fast and efficient sheet metal forming method for the targeted modification of component properties.", "isbn" : "978-3-031-40919-6", "booksubtitle" : "ICTP 2023 - Volume 2", "bookpagination" : "page", "file" : "Briesenick, Liewald et al. 2024 - Plate Roll Embossing Process:Attachments/Briesenick, Liewald et al. 2024 - Plate Roll Embossing Process.pdf:application/pdf", "location" : "Cham", "doi" : "10.1007/978-3-031-40920-2_9", "bibtexKey": "Briesenick.2024" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2a44564fccd490b1c5718fc940deeb90c/ifu", "tags" : [ "KR","MG","ML","PH","imported" ], "intraHash" : "a44564fccd490b1c5718fc940deeb90c", "interHash" : "b3b14348307e6f0f5c6cfd3d6b4fa94d", "label" : "A strategy for minimizing the computational time of simulations involving near-surface embossing of sheet metal materials", "user" : "ifu", "description" : "", "date" : "2024-07-30 13:19:36", "changeDate" : "2025-04-28 13:25:38", "count" : 2, "pub-type": "article", "booktitle": "Material Forming: ESAFORM 2024","series": "Materials Research Proceedings","publisher":"Materials Research Forum LLC", "year": "2024", "url": "https://doi.org/10.21741/9781644903131-249", "author": [ "Pascal Heinzelmann","Marcel Görz","Kim Rouven Riedmüller","Mathias Liewald" ], "authors": [ {"first" : "Pascal", "last" : "Heinzelmann"}, {"first" : "Marcel", "last" : "Görz"}, {"first" : "Kim Rouven", "last" : "Riedmüller"}, {"first" : "Mathias", "last" : "Liewald"} ], "volume": "41","pages": "2262--2270","abstract": "By near-surface embossing, work hardening can be introduced into sheet metal blanks, thus increasing the material´s yield strength. Hence, this property-modifying process can be used to improve the lightweight potential of a component on the one hand and its crash performance on the other. For the early design of such embossing or forming processes and to predict the modification of the material properties, FE modelling is currently used. Here, the embossing of the near-surface structures is usually simulated first, followed by the forming process. However, existing simulation methods are time-consuming and computationally intensive, due to the simulation of the whole embossing process. For this purpose, this paper presents two approaches for improving the simulation time of embossing and forming processes. Compared to the conventional holistic embossing and forming simulation, these approaches are based on a new mapping strategy and experimental data. In the mapping variant, solid elements\u2019 stress and strain distribution is mapped to shell elements, thus including the embossing history for the forming simulation. For the experimental-based variant, the yield curves of embossed tensile tests are determined and used to approximate the property changes in the simulation.

The application of\r\nan adaptive SPH method requires a criterion which reliably\r\nidentifies particles to be split or merged. The definition of a\r\nphysical criterion is often not easy as it requires prior knowledge\r\nof the system to be investigated. This urges the need for a\r\nuniversal adaptivity criterion which is not dependent on the\r\nphysical system\u2019s properties. The so-called SPH interpolation\r\nmoments matrix can be taken as a measure of the discretization\r\naccuracy actually achieved. It makes use of the zeroth- and first\u0002order consistency conditions of the SPH interpolation and should\r\nbe identical with the identity matrix of the given dimension.\r\nDeviations of this matrix from the ideal form may result from (i)\r\nan insufficient spatial resolution of the model domain, (ii) a non\u0002uniformity of the neighboring particles\u2019 distribution, and (iii)\r\na truncated kernel-support at free surfaces. Up to now, there\r\nis no strategy allowing to distinguish between the influences\r\non the matrix following from the different error sources. To\r\ndeduce such a strategy, the structure of the matrix is thoroughly\r\nanalyzed and its changes due to the three named influences\r\nwere determined with the help of randomly generated and\r\nhomogeneously distributed grids and a bursting dam example\r\nusing the software Pasimodo.", "file" : "Heinzelmann, Spreng et al. 2021 - Analysis of the SPH interpolation:Attachments/Heinzelmann, Spreng et al. 2021 - Analysis of the SPH interpolation.pdf:application/pdf", "language" : "en", "doi" : "10.18419/OPUS-11504", "bibtexKey": "Heinzelmann.2021" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2fa0cc72a8d6e25917ed83e1e8f3aceab/ifu", "tags" : [ "imported","PH","DB","ML" ], "intraHash" : "fa0cc72a8d6e25917ed83e1e8f3aceab", "interHash" : "881ac1fa2b39b0cddea3fba19e7e4ff5", "label" : "Characterization of the Mechanical Properties of Selectively Embossed Sheet Metal Materials Under Multi-Axial Loads", "user" : "ifu", "description" : "", "date" : "2024-06-12 11:49:25", "changeDate" : "2024-06-12 11:49:26", "count" : 4, "pub-type": "article", "year": "2023", "url": "https://iopscience.iop.org/article/10.1088/1757-899X/1284/1/012043/meta", "author": [ "Pascal Heinzelmann","David Briesenick","Mathias Liewald" ], "authors": [ {"first" : "Pascal", "last" : "Heinzelmann"}, {"first" : "David", "last" : "Briesenick"}, {"first" : "Mathias", "last" : "Liewald"} ], "volume": "1284","number": "1","pages": "012043", "pagination" : "page", "language" : "en", "shortjournal" : "IOP Conf.

It is hypothesized that three pH components would occur in the 31P-MRS during fatigue, representing three fiber types.\n\nMethods\nThe medial gastrocnemius of eight subjects was stimulated within a 3-Tesla whole body MRI scanner. The maximal force during stimulation (Fstim) was examined by a pressure sensor. Phosphocreatine (PCr), adenosintriphosphate, inorganic phosphate (Pi), and the corresponding pH were estimated by a nonvolume-selective 31P-MRS using a small loop coil at rest and during fatigue.\n\nResults\nDuring fatigue, Fstim and PCr decreased to 27% and 33% of their initial levels, respectively. In all cases, the Pi peak increased when NMES was started and split into three different peaks. Based on the single Pi peaks during fatigue, an alkaline (6.76\u2009±\u20090.08), a medium (6.40\u2009±\u20090.06), and an acidic (6.09\u2009±\u20090.05) pH component were observed compared to the pH (7.02\u2009±\u20090.02) at rest.\n\nConclusion\nIt is suggested that NMES is able to induce pH heterogeneity in the medial gastrocnemius, and that the single Pi peaks represent the different muscle fiber types of the skeletal muscle.
