A conceptual wearable monitoring system for physiological indices and clothing microclimate measurement

Abstract

Purpose The purpose of this paper is to investigate physiological indices related to comfort and health condition, based on which corresponding electronic equipment are selected and applied. A wearable monitoring system using sensor and liquid crystal display (LCD) techniques are then designed. Sensors are used to collect and transmit recording required signals from the wearer. A microcomputer with the type of AT89C52 is used to record and analyze the collected data. LCD is applied to display the health and comfort condition of the wearer. Design/methodology/approach A novel wearable monitoring system for the measurement of physiological indices and clothing microclimate is proposed in this study in order to monitoring both health and comfort condition of the wearer. Findings The proposed system provides reference for the application of sensor and display technologies in the field of smart clothing, which can be further applied to infant and child care, health care, home entertainment, military and industry. Originality/value This paper, first, investigated a framework of a wearable monitoring system considering both comfort and health condition and summarized the related physiological indices. The requirements of both comfort and health condition monitoring are analyzed to select appropriate electronic elements.

Virtual Design Method of Customized Clothing Based on Three-Dimensional Image

“…Taking the left shoulder as an example, the extraction steps of shoulder points are described in detail. Except for the direction, the right shoulder points are the same [16].…”

Infection prevention and early warning in neonatal intensive care unit based on physiological sensor monitoring

“…A physiological sensor is a kind of intelligent sensor device, which is currently used in medicine, healthcare, monitoring and other fields. Hong Y integrated the wireless communication network into the physiological sensor and finally realized the remote acquisition of the patient’s physiological signal, which freed the patient from the shackles of medical monitoring equipment ( Hong et al, 2019 ). Chen C developed a smart physiological sensor using state-of-the-art optical chip technology.…”

Tolerable range of abdomen and waist skin temperature for heating-capable smart garments

“…Smart clothing is expected to expand into everyday life with the evolution in materials and the development of information and communications technology. Among them, temperaturemonitoring smart clothing equipped with heat-generating textile materials and a temperature control system has been one of the major items attracting the attention of individuals who enjoy winter sports activities, patients who need local heating for thermotherapy and groups who need thermal protection such as soldiers and workers (Hong et al, 2019;Jayathilaka et al, 2019;Kumar and Sajithira, 2019). Thermal management of clothing is now considered as a beneficial way of energy savings to reduce heating energy of buildings (Jayathilaka et al, 2019;Peng et al, 2019).…”

“…Thermal management of clothing is now considered as a beneficial way of energy savings to reduce heating energy of buildings (Jayathilaka et al, 2019;Peng et al, 2019). For the smart clothing, considerable efforts have been made to develop efficient heat-generating conductive materials using carbon nanotubes (Aziz and Chang, 2018;Walczak and Maciej, 2014;Wang and Loh, 2017), graphene (Karim et al, 2017;Peng et al, 2019;Sui et al, 2011), silver Skin temperature and smart garments 929 nanowire (Huang et al, 2019;Kumar and Sajithira, 2019) or poly-ethylenedioxythiophene (Hong et al, 2019;Peng et al, 2019) and polystyrene sulfonate ( Akerfeldt et al, 2014;Foroughi et al, 2011;Moraes et al, 2017). To be widely accepted by the consumer, smart clothing needs to be durable, convenient and comfortable to wear during daily life without causing any unobtrusiveness during wear (Roh and Kim, 2016).…”

“…In fact, warming the innermost microclimate is more energy-saving compared to warming microclimate between the clothing layers by the heating device attached to the outerwear. Next-to-skin innermost microclimate has been noted as an important space for clothing comfort (Hong et al, 2019;Kumar et al, 2015;Lim et al, 2015;Peng et al, 2019), and it is a more effective place for heating than the outer layer where heat is directly lost to the cold environment due to the large temperature gradient between the warm outer surface and the cold environment. However, there is a lack of research on the smart base layer with a heating device in a multilayered wear condition, so far.…”
