While the concept is mature, issues surrounding sampling convenience and device adoption as well as maintaining signal quality under artifacts remain a problem. In this article, we present a high-performing wearable ECG armband on the upper left arm. It is equipped with miniaturized hardware, capable of data storage and wireless communication. We evaluate different electrode configurations by conducting ECG measurements both at the static state and under motion and using improved algorithms to quantify data quality and assess the agreement between the proposed new technique and the gold standard. The optimal electrode position is determined by balancing wearable suitability and signal quality. We propose an electronic textile (E-textile) armband with improved design. It offers favorable wearing comfort and a fashionable appearance without sacrificing data quality. Its contact pressure is measured to get a better picture of intimacy and clothing comfort. Our system provides real-time and noise-resilient ECG data without interrupting daily life and can be implemented in use cases that warrant continuous ECG monitoring.}, number={19}, journal={IEEE SENSORS JOURNAL}, author={Zhou, Yilu and Mohaddes, Farzad and Lee, Courtney and Rao, Smriti and Mills, Amanda C. and Curry, Adam C. and Lee, Bongmook and Misra, Veena}, year={2022}, month={Oct}, pages={18970–18977} } @article{mohaddes_islam_padhye_wang_2022, title={Durable and Environmentally Friendly Flame-Retardant Finish on Wool via Graft Copolymerization of Vinyl Acid}, volume={12}, ISSN={["2069-5837"]}, DOI={10.33263/BRIAC123.36473663}, abstractNote={A durable and environmentally friendly flame-retardant treatment process on wool via graft co-polymerization of vinyl phosphonic acid (VPA) was investigated. The influence of temperature, time, VPA, and catalyst on the grafting yield (GY) was studied. Employing response surface methodology, the grafting parameters were optimized, and the highest GY was achieved. Thermogravimetric studies showed a 3.86% increase in the remaining char ratio at 750°C for the wool fabric after graft co-polymerization of VPA. Flame retardancy of wool fabrics was evaluated with respect to their limiting oxygen indices (LOI) and the ease of ignition measurements. The sample with 8.1% GY exhibited a 35.89% increase in LOI and over a 3.66-fold increase in ignition time. The chemical structure of the grafted wool is proposed according to FTIR and 31P Solid-state MAS NMR evidence. The presented flame-retardant finish process was deemed to be a green and durable substitute for the conventional, semi-durable, and non-environmentally friendly processes.}, number={3}, journal={BIOINTERFACE RESEARCH IN APPLIED CHEMISTRY}, author={Mohaddes, Farzad and Islam, Saniyat and Padhye, Rajiv and Wang, Lijing}, year={2022}, month={Jun}, pages={3647–3663} } @article{polash_mohaddes_rasoulianboroujeni_vashaee_2021, title={Magnon-drag thermopower in antiferromagnets versus ferromagnets (vol 8, pg 4049, 2020)}, volume={9}, ISSN={["2050-7534"]}, DOI={10.1039/d1tc90030g}, abstractNote={Correction for ‘Magnon-drag thermopower in antiferromagnets versus ferromagnets’ by Md.

After an overview of wearables market trends, different active and passive methods of body energy harvesting for powering low-consumption electronic devices are introduced, and challenges of device fabrication are discussed. The discussion continues with the primary emphasis on thermoelectric generators for body heat harvesting. The physiological aspects of the human body involved in heat generation are elaborated. System requirements and the influence of different parameters on the performance of thermoelectric generators are studied at the material, device, and system levels. Finally, the advancements in the development of rigid and flexible thermoelectric generators for wearable and textile integration are presented.}, journal={APPLIED ENERGY}, author={Nozariasbmarz, Amin and Collins, Henry and Dsouza, Kelvin and Polash, Mobarak Hossain and Hosseini, Mahshid and Hyland, Melissa and Liu, Jie and Malhotra, Abhishek and Ortiz, Francisco Matos and Mohaddes, Farzad and et al.}, year={2020}, month={Jan} }
