“…A wearable sensor for online health monitoring has been studied by some researchers (Kumar et al , 2023a, 2023b). Some typical applications for such sensors are in biotelemetry detection of brain cancer (Raihan et al , 2017), breast cancer (Nesasudha, 2021, Fusic et al , 2023), measurement of the dielectric property of porcine skin tissue for the implantable purpose (Karacolak et al , 2012), evaluation of psychological and physiological well-being of dairy cattle (Bjarnason et al , 2013), determination of glucose blood level (Deshmukh and Chorage, 2020). The in-body patch antenna has been used to remotely check the pacemaker’s functionality and condition.…”
