of Printed Hybrid Electronics Assemblies Speaker: Alison Kritz | Company: Parsons | Date: 11-12 May 2021 | Full Presentation We will present an investigation of risks of failure in a prototype printed hybrid electronics (PHE) Arduino-type circuit to be fabricated using a variety of additive manufacturing technologies including aerosol-jet, syringe, and stereolithography (SLA) printing. The interfaces of different components and materials in this design introduce potential sources of failure including thermal expansion mismatches and silver migration resulting from temperature cycling. We will discuss the design rationale, fabrication methods, and testing conditions of three different test coupons, each of which isolates a different area of interest in the PHE assembly and seeks to identify and prevent the greatest risks.

UBC researchers have created what could be the first battery that is both flexible and washable. It works even when twisted or stretched to twice its normal length, or after being tossed in the laundry. The battery is described in a new paper published recently in Advanced Energy Materials “Wearable electronics are a big market and stretchable batteries are essential to their development,” says Dr. Ngoc Tan Nguyen (he/him), a postdoctoral fellow at UBC’s faculty of applied science. “However, up until now, stretchable batteries have not been washable. This is a critical addition if they are to withstand the demands of everyday use.” The battery developed by Dr. Nguyen and his colleagues offers a number of engineering advances. In normal batteries, the internal layers are hard materials encased in a rigid exterior. The UBC team made the key compounds—in this case, zinc and manganese dioxide—stretchable by grinding them into small pieces and then embedding them in rubbery plastic, or polymer. The battery comprises several ultra-thin layers of these polymers wrapped inside a casing of the same polymer. This construction creates an airtight, waterproof seal that ensures the integrity of the battery through repeated use. It was team member Bahar Iranpour (she/her), a Ph.D. student, who suggested throwing the battery in the wash to test its seal. So far, the battery has withstood 39 wash cycles and the team expects to further improve its durability as they continue to develop th...

NTU Singapore scientists develop biodegradable printed paper batteries Once expended, eco-friendly batteries break down in soil within weeks Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed paper-thin biodegradable zinc batteries that could one day become an environmentally sustainable option for powering flexible and wearable electronic systems. The NTU Singapore-developed zinc batteries are made up of electrodes (through which the electrical current leaves or enters the battery) screen-printed on both sides of a piece of cellulose paper that has been reinforced with hydrogel. Once the battery has been expended, it can be buried in soil, where it breaks down completely within a month. In a proof-of-concept experiment described in the scientific journal Advanced Science, the NTU team demonstrated how a 4cm x 4cm square printed paper battery could power a small electric fan for at least 45 minutes. Bending or twisting the battery did not interrupt the power supply. In another experiment using a 4cm x 4cm battery to power an LED, the scientists showed that despite cutting away parts of the paper battery, the LED remained lit, indicating that cutting does not affect the functionality of the battery. The scientists think their printed battery could be integrated into flexible electronics such as foldable smartphones that are already on the market, or biomedical sensors for health monitoring. Professor Fan Hongjin from the NTU School ...

Enabling fine wire printing at 30 μm and less, with potential to further improve transparency and flexibility for electronic devices such as display devices and next-generation automotive window defoggers TANAKA Kikinzoku Kogyo K.K. (Head office: Chiyoda-ku, Tokyo; Representative Director & CEO: Koichiro Tanaka), which operates the TANAKA Precious Metals manufacturing business, announced today that TANAKA has developed a Low-Temperature Sintering Nano-Silver Paste for Printed Wiring optimized for screen printing1 and current availability of samples. This product enables miniaturization and improved bending resistance of wiring, for use in screen printing, which is a mainstream printing method used in the field of printed electronics. For this reason, it is expected to be widely used for flexible devices such as smartphones and wearable devices that need bending resistance, and for improving transparency in window defoggers and other products for which demand will grow as electric vehicles become more popular. Product Features ■ Paste suited to printing fine wires of 30 μm and less Normally, the limit for printing wires in the screen printing process is about 50 μm in width. However, by combining suitable printers and screens with this paste, it is possible to print fine wires (30 μm and less) directly onto glass, which is a difficult medium for fine-line printing, and onto other materials such as PET film3 and green sheets. This will enable higher performance and improv...

The PCBs are automatically placed on your fabric by the high-accuracy robotic feeder. The boards are stacked and stored in a magazine which can be automatically integrated into your E-Textile by a ZSK embroidery machine. The circuit boards are then fixed to the fabric by thread and needle. After the fixation of the PCB, the electrical connection can be embroidered by a conductive thread automatically. This way electrical connections between different PCBs can be embroidered in a fully automatic and highly scalable fashion. The embroidery machine can complete electrical circuitries including PCBs, sensors, actors, and tracks. Your E-Textiles can be completed automatically! By using the PCB Placement Devices with a multi-head embroidery machine, upscaling and mass-production of E-Textiles is easy. The PCB- Placement Device has been developed in cooperation with Robert Bosch GmbH, Germany. The PCBs can be individually designed and produced by BOSCH to suit your custom project needs.

Some studies have shown that nicotine, an addictive substance in electronic cigarettes, increases the risk of cardiovascular and respiratory disorders. But to get a full understanding of its potential health effects, a real-time nicotine monitoring device is needed. Such a device could also help vapers as well as non-vapers who encounter second-hand smoke measure their exposure. Now, researchers report in ACS Sensors that they have developed a battery-free, wearable device that could accomplish this task. E-cigarettes are designed to heat and aerosolize a mixture of nicotine, glycerine, propylene glycol, and flavoring additives, which the user then inhales. In the body, this mixture can affect multiple organs, including the respiratory system, where it alters airflow, increases oxidative stress, and impairs immunity. In addition, nicotine exposure can lead to lung cancer. But assessing that exposure under real-world conditions has been difficult. Current assays for measuring ambient nicotine levels are carried out in laboratory settings and require large sample volumes and days to weeks of sampling. Portable nicotine sensors are being developed as an alternative, but the two that have been reported are impractical because they rely either on the presence of sweat or sunlight to function. So Madhu Bhaskaran, Md. Ataur Rahman and Philipp Gutruf set out to design a lightweight, wearable sensor capable of detecting nicotine in real-time and sending the data wirelessly to elect...
