“…As part of this initiative, faculty were provided with release time from one course to redesign their curriculum. The purpose of the course redesign was to give students an active learning experience that integrated new empirically supported health technology, research methodologies, and equipment that has been used to collect stress and health data across different at-risk populations (Motti, 2020; Urizar et al, 2020). More specifically, research methodologies representing the areas of engineering, biology, health science, and behavioral medicine were incorporated for different topics in the course syllabus (e.g., stress measurement, epigenetics, biological stress responses, muscle and sleep physiology) to provide students with classroom demonstrations and hands-on activities that were designed to strengthen their understanding of core course concepts.…”

The number of health psychology courses offered in higher education institutions has dramatically increased over the past 30 years. Health psychology courses provide students a unique opportunity to learn about important public health issues and health disparities affecting our society from a biopsychosocial perspective. Prior research indicates that students taking these courses, many of whom are non-biology majors, often report feeling anxious about learning the underlying biological mechanisms that affect health outcomes, particularly as they relate to stress and disease. Therefore, innovative teaching strategies, such as the use of active learning approaches, are needed to promote student confidence and engagement in learning these interdisciplinary models of health. Despite rapid advancements and innovations in health technologies, few health psychology courses have integrated these technologies as a modality of active learning. This article describes the implementation of health technologies (e.g., biosensors, biofeedback equipment, wearable technologies) as an active learning modality and innovative teaching approach to promote student engagement and learning outcomes in an undergraduate health psychology course taught in the U.S. Eighty students from a minority-serving university participated in this pilot course redesign. Student responses to the use of health technologies in their course were very positive. A description of the course curriculum is provided and results from student responses and feedback are presented. Implications and recommendations for implementing these technologies and pedagogies in future health courses are also discussed, including university support for sustaining these high impact teaching practices.

“…An automated electrochemiluminescence test (ECLIA) called the Roche Cortisol II test is also used [15]. There have been many reports of the use of biosensors for the detection of cortisol [16][17][18][19][20][21][22][23][24][25][26][27][28]. These are summarized in Table 1.…”

Cortisol is a hormone which plays an essential role in the immune, endocrine, cardiovascular, renal and skeletal systems. Its level increases in response to stress, illness, injury or exhaustion, and it is therefore a significant diagnostic biomarker of stress. An immunosensor for the determination of cortisol by SPRi array was developed. The receptive part of the immunosensor is mouse monoclonal antibody against cortisol, immobilized via cysteamine linker. The optimum pH of the immunosensor is 7.4, and the optimum concentration of the antibody is 50 ng mL−1. The immunosensor is specific for cortisol, and its linear response ranges from 0.20 ng mL−1 (LOQ) to 8 ng mL−1. The precision of the determination was between 3.1% and 3.3%, and the recovery between 99% and 102%. The immunosensor was validated by simultaneous determination of cortisol in serum and saliva samples by a standard method, with good agreement between the results.
