Studies on the mechanical stretchability of transparent conductive film based on graphene-metal nanowire structures

Transparent electrodes with superior flexibility and stretchability as well as good electrical and optical properties are required for applications in wearable electronics with comfort designs and high performances. Here, we present hybrid nanostructures as stretchable and transparent electrodes based on graphene and networks of metal nanowires, and investigate their optical, electrical, and mechanical properties. High electrical and optical characteristics, superb bendability (folded in half), excellent stretchability (10,000 times in stretching cycles with 100% in tensile strain toward a uniaxial direction and 30% in tensile strain toward a multi-axial direction), strong robustness against electrical breakdown and thermal oxidation were obtained through comprehensive study. We believe that these results suggest a substantial promise application in future electronicsopen1

Parental personality, mental health, and fear of happiness as predictors of perceived coparenting relationship quality among mothers and fathers of preschoolers

Objective Existing theoretical models and research findings highlight individual parent characteristics as contributors to coparenting relationship quality. Yet less is known about how indices of parental personality, beliefs, and mental health symptoms relate to coparenting perceptions among parents of preschoolers. This study examines direct and indirect paths connecting parents’ Big Five personality traits, fear of happiness, and depression and anxiety symptoms with perceived coparenting quality. Method Using an online survey design, 160 parents (81 mothers; 79 fathers) of preschoolers (age 2–5 years) completed the Ten-Item Inventory of Personality, Fear of Happiness Scale, Patient Health Questionnaire-4, and Coparenting Relationship Scale – Brief Form. Results Parental Emotional Stability negatively related to anxiety and depressive symptoms and to fear of happiness. Anxiety symptoms and fear of happiness directly, and negatively, related to coparenting quality. Emotional stability was indirectly, positively related to coparenting quality via lower levels of parental anxiety and fear of happiness. Although parental depressive symptoms were unrelated to coparenting quality, parents’ Openness to Experience and fear of happiness positively predicted depressive symptoms. Conclusion Findings suggest parents’ anxiety symptoms and fear of happiness may underlie the processes by which parental Emotional Stability relates to perceived coparenting quality among parents of preschoolers

Exploring Mothers’ and Fathers’ Reported Use of Discipline Practices With Their Preschoolers: Associations With Parental Well-Being

Supporting parents in use of effective, evidence-based discipline remains an important goal for research, practice, and policy. This study explored parental well-being and reported discipline practices with preschoolers (2–5 years). Parents (N = 205; 97 fathers) completed a Qualtrics-based survey assessing discipline practices, feelings of judgment in the parental role, anxiety and depression symptoms, and fear of happiness. Parents higher on anxiety used greater structure/limit setting. Higher parental anxiety and depression symptoms related to greater fear of happiness, and fathers higher on anxiety reported greater judgment in the parental role. For mothers, fear of happiness was modestly and positively associated with use of directive/punitive discipline and negatively associated with use of structure/limit setting. Results suggest parental well-being may be linked to discipline use in unique ways for mothers and fathers. Findings can support researchers and community professionals in understanding an array of parental characteristics that may relate to discipline practices

Skin-interfaced biosensors for advanced wireless physiological monitoring in neonatal and pediatric intensive-care units

Standard clinical care in neonatal and pediatric intensive-care units (NICUs and PICUs, respectively) involves continuous monitoring of vital signs with hard-wired devices that adhere to the skin and, in certain instances, can involve catheter-based pressure sensors inserted into the arteries. These systems entail risks of causing iatrogenic skin injuries, complicating clinical care and impeding skin-to-skin contact between parent and child. Here we present a wireless, non-invasive technology that not only offers measurement equivalency to existing clinical standards for heart rate, respiration rate, temperature and blood oxygenation, but also provides a range of important additional features, as supported by data from pilot clinical studies in both the NICU and PICU. These new modalities include tracking movements and body orientation, quantifying the physiological benefits of skin-to-skin care, capturing acoustic signatures of cardiac activity, recording vocal biomarkers associated with tonality and temporal characteristics of crying and monitoring a reliable surrogate for systolic blood pressure. These platforms have the potential to substantially enhance the quality of neonatal and pediatric critical care
