- Graphene based electronic tattoo technologies for complex electrophysiology
Speaker: Dmitry Kireev | Company: University of Texas | Date: 2-Dec-22 | Full Presentation Monitoring complex health-related electrophysiological signals such as arterial blood pressure (BP) in ambulatory settings is essential for a proper understanding of health conditions, predominantly cardiovascular diseases. Moreover, continuous long-term monitoring of BP for patients with sleep apnea, stroke, or hypertension is essential to understand their health risk factors and build preventative care routines. While conventional ambulatory BP monitoring devices exist, they are uncomfortable, bulky, and intrusive. The common drawbacks of all these systems are their bulkiness and incompatibility with skin’s elastic properties, causing sensor’s displacement during usage, consequently requiring frequent system re-calibration. In our work, we introduce a unique wearable BP monitoring technology that leverages atomically-thin and electrically conductive graphene electronic tattoos (GETs) as main building blocks. The GETs are placed over the radial and ulnar arteries on the wrist and subsequently used as current injection and voltage sensing electrodes, measuring arterial bioimpedance. In contrast to any other wearable system, the atomically thin, lightweight, and skin-conformable GETs do not apply any external tension onto the skin during the operation. Hence, they are able to perform long-term and nocturnal measurements without discomforting the subjects. Using bioimpedance modality allows us to disregard the tattoo-skin interface, which is typically 2-4 orders of magnitude larger compared to tissue impedance, and record only from the areas of interest. Employing a machine learning regression model on the recorded bioimpedance value, we yield effective beat-to-beat detection of diastolic and systolic BP values with grade-A accuracy. Besides BP, we show that the same Bio-Z signal can be post-processed to estimate person’s RR in an entirely wearable and non-invasive manner.

- Arterial Pulse Wave Monitoring: Self-Powered, Highly Unobtrusive, Low-Cost and Accurate
Speaker: Mika-Matti Laurila | Company: Tampere University | Date: 2-Dec-22 | Full Presentation Self-powered, highly unobtrusive, low-cost and accurate arterial pulse wave monitoring devices need to be developed to enable cost-efficient monitoring of entire cardiovascular disease risk groups. Wearable sensors with ultra-thin form factor have been recently developed to meet these demands, but the scalable fabrication of such devices has not been addressed sufficiently and the accuracy of the devices more in-depth investigation. In our study, we report the development of a printing based fabrication process for a highly unobtrusive piezoelectric ultra-thin (t ~ 4,2 µm) e-tattoo arterial pulse wave sensor which utilizes only transparent and biocompatible polymer-based materials. The ferroelectric performance of the ultra-thin P(VDF-TrFE) material layer is optimized through the use of crosslinked PEDOT:PSS electrodes; this results in ~70 % and ~34 % improvements in remanent polarization (Pr) and coercive field (Ec), respectively, when compared to the sensors with pristine PEDOT:PSS electrodes. The ultra-thin form factor enables access to the high bending mode sensitivity of the P(VDF-TrFE) material layer; the maximum sensitivity value achieved in uniaxial and multiaxial bending is ~1700 pC N-1, which is ~50 times higher than the measured normal mode sensitivity. The increased sensitivity is linked to a specific set of direct piezoelectric coefficients using combination of experimental results, statistical analysis and finite element modeling. Finally, the accuracy of the e-tattoo sensor is demonstrated in the non-invasive measurement of radial artery pulse wave by comparing the signal to that obtained with reference device from 7 study subjects.

- Dry Multimaterial Printer: An Ink-less Technology with On-Demand Generation
and Real-time Sintering of Pure Nanoparticles Speaker: Masoud Mahjouri-Samani | Company: NanoPrintek | Date: 2-Dec-22 | Full Presentation The world is rapidly moving toward the internet of things (IoT), where everything around us will be made smart, and so does the need for low-cost, eco-friendly, and fast design-to-manufacturing technologies to integrate various electronics and devices onto these objects. This has led to a high interest in additively manufactured electronics (AME) or so-called printed electronics, as it can potentially enable IoT with a wide range of applications in electronics, healthcare, automotive, aerospace, defense, and energy industries. However, the current printing technologies are based on wet printing methods such as inkjet and aerosol jet printers that suffer from complex and expensive ink formulation, limited printing material options, contaminations, and time-consuming post-processing. This talk will present the world’s first “dry multimaterial printer” that transforms the printing of functional materials and devices for electronics, energy, healthcare, agriculture, transportation, and defense applications. This disruptive technology revolutionizes printing from a traditional liquid-based to dry printing technology. The Key technology advantages include 1) on-demand and in-situ generation of various pure nanoparticles without contaminations, 2) in-situ and real-time laser sintering of nanoparticles on various substrates with no further post-processing, 3) multimaterial printing of hybrid and composite materials and structures. The liquid-free nature of the system, the tunable flow dynamic of the nanoparticles, and the real-time sintering mechanism make it uniquely suitable for operating both on the earth and in space. Moreover, this technology is capable of printing sensitive materials such as copper on biodegradable substrates such as paper.

- Stretchable piezo-resitive yarns for strain sensing in high deformation systems
Speaker: Paul Fowler | Company: MesoMat | Date: 2-Dec-22 | Full Presentation MesoMat has developed plastic based yarns which are able to conduct electricity even as they are stretched like a rubber band. This material, which consists of many polymer filaments that are each coated with conductive nanoparticles and bundled into a yarn, is piezo-resistive, meaning as it is stretched or compressed there is a change in its electrical conductivity. Therefore, these yarns offer a simple method to sense strain which provides numerous advantages over conventional sensing techniques. Most importantly, whereas most commercially available strain gauges can measure strains on the order of 1% at most, these sensing yarns are able to measure strains as large as 20%, making them ideally suited for high deformation environments such as the human body. Secondly, in contrast with traditional point sensors which provide feedback at specific locations, these yarns are global sensors and detect strain anywhere along their length. Sensing yarns are combined with electronics and software to provide a complete platform that can be used to measure performance, optimize manufacturing or detect failure in high strain materials that are otherwise difficult to sense such as composites, plastics, rubbers and textiles. Example use cases range from monitoring widely used industrial and automotive components to sensing in garments and wearables.

- High-Throughput Roll-to-Roll Research for High-Performance Roll-to-Roll Fabricated Organic
and Perovskite PV Modules Speaker: Doojin Vak | Company: CSIRO Manufacturing | Date: 14 - 15 Dec 2022 | Full Presentation Organic photovoltaics (OPV) and organic-inorganic hybrid perovskite photovoltaics (PePV) are promising PV technologies that can be manufactured using industrial roll-to-roll (R2R) printing which is a widely used mass-production technique for low-cost products. These emerging PV technologies have been making exciting progress toward commercial applications and the efficiencies of the laboratory cells (19.2 % for OPV and 25.7 % for PePV) are already high enough to enter the PV market. However, the efficiency of R2R-produced PV still lags behind those achieved for champion laboratory cells. This is attributed to the materials, processes and device configurations developed for research purposes not being readily translatable to R2R printing, with significant material and process optimisation required to achieve compatibility with scalable R2R processes. The time-consuming optimisation process has delayed the translation of these technologies to the marketplace, necessitating a new revolutionary research method. Here we present an automated R2R research platform to accelerate the progress of R2R-fabricated solar cell technologies. A bespoke R2R coater was developed to optimise formulations and fabrication parameters including deposition conditions, coating speed, and annealing temperature. An in-situ formulation technique was introduced to fabricate over 10,000 unique cells a day via unmanned operation, and an automated R2R PV measurement unit has also been developed to test this number of cells in a single day. This innovative approach has enabled the rapid progress of R2R-fabricated solar cells, resulting in vacuum-free R2R-fabricated PePV and OPV devices achieving PCEs of 17% and 10%, respectively, both of which are record PCEs in their class, and with the technology still improving rapidly. The optimised parameters have also been translated to the R2R fabrication of large-area modules. The recent progress on the upscaling will also be presented.
