The sensor can either be mounted on myocardial tissue and monitor the electrocardiography (ECG) with contact electrodes or implanted under the skin and monitor the ECG with coaxial leads. A 16\u2010bit high\u2010resolution analog front\u2010end (AFE) and an energy\u2010efficient 32\u2010bit CPU are used for instantaneous ECG recording. Wireless data transmission between the sensor and clinician\u2019s computer is achieved by an embedded low\u2010power Bluetooth transmitter. In order to automatically recognize the working status of the pacemaker and alarm the episodes of arrhythmias caused by pacemaker malfunctions, pacing mode classification and fault diagnosis on the recorded ECG were achieved based on an AI algorithm, i.e., a resource allocation network (RAN). A prototype of the sensor was implemented on a human torso, and the <jats:italic>in vitro<\/jats:italic> test results prove that the sensor can work properly for the 1\u20104\u2010meter transmission range.<\/jats:p>","DOI":"10.1155\/2021\/8444015","type":"journal-article","created":{"date-parts":[[2021,12,14]],"date-time":"2021-12-14T03:50:35Z","timestamp":1639453835000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["In\u2010Body Electromagnetic Sensor Combined with AI\u2010Enhanced Electrocardiography for Pacemaker Working Status Telemonitoring"],"prefix":"10.1155","volume":"2021","author":[{"given":"Wu","family":"Lu","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4535-5118","authenticated-orcid":false,"given":"Ranran","family":"Ding","sequence":"additional","affiliation":[]},{"given":"Bingjie","family":"Wu","sequence":"additional","affiliation":[]},{"given":"Wenbin","family":"Zhao","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2872-6164","authenticated-orcid":false,"given":"Dong","family":"Huang","sequence":"additional","affiliation":[]},{"given":"Xue","family":"Zhang","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,12,13]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1007\/s13753-019-00237-x"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.23919\/ChiCC.2019.8865575"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2017.2735441"},{"key":"e_1_2_8_4_2","article-title":"The development of programming and telemetery system for cardiac pacemaker","volume":"32","author":"Zhu Z.
