German Jordanian University
BiographyJumana M. Abu-Khalaf received the B.S. degree in mechatronic engineering from the University of Jordan, Amman, Jordan, in 2005, and the Ph.D. degree in mechanical engineering from the University of Utah, Salt Lake City, in 2012. She is currently an Assistant Professor with the Department of Mechatronics Engineering, German Jordanian University, Amman, Jordan. Her current research interests include robotics and control, mechatronics, haptics, and bioinstrumentation. Dr. Abu-Khalaf has several publications and a patent in the area of stretchable circuits. She received the University of Utah’s NSF Biocentric Robotics IGERT Fellowship for the period 2007-2009. She is a member in IEEE and the American Association for the Advancement of Science (AAAS).
Wearable Stretchable Sensors for Physiological MonitoringRemote monitoring of human physiological parameters is becoming a necessity due to the increased life expectancy in most countries, which is giving rise to the proportion of elderly in the population. This is expected to burden the current medical and social welfare systems financially, which will result in reduced quality in the provided health care. Hence, it is desired to develop cost-effective and easy-to-use technological solutions that allow for monitoring elderly patients, as well as immobile patients, in their homes. Using non-invasive wearable sensors can allow for the remote monitoring of vital signs such as heart rate, respiratory rate, body temperature, and blood pressure in real time. These parameters could be used to make initial diagnoses of the physical condition of the patient and alarm medical professionals in the case of an emergency. Specifically, monitoring the heart rate and oxygen saturation can help in the early detection of cardiovascular diseases which resulted in 37% of the total deaths in Jordan alone in the year 2017. Existing remote sensing solutions are expensive and bulky making them uncomfortable to be worn especially by the elderly. Therefore, the development of fabrication techniques to allow for remote health monitoring without hindering the natural activity of the patient, is crucial. The human body curvature being two-dimensional requires the fabrication of stretchable rather than flexible sensors. Several fabrication techniques that allow for patterning conductive lines on stretchable substrates, such as lithography, inkjet printing, and screen printing, will be discussed.
