Based on the electrical properties of soils, the paper extends the existing CPT air coupler model into a more generalized model. The autonomous push-pull inverter is selected to power the CPT system and modified to further the data transmission range. With a designed load shift keying (LSK) circuitry, this self-oscillating inverter regards the data as a sequence of impedance changes, resulting in operation frequency drifts. A Frequency Shift Keying (FSK) demodulator is applied to capture the frequency variations and recover back to data. The proposed design has been simulated, verified, and implemented on a complete prototype. Various testings have been carried out, and the results are satisfactory.<\/jats:p>","DOI":"10.1155\/2020\/8849618","type":"journal-article","created":{"date-parts":[[2020,9,15]],"date-time":"2020-09-15T23:35:07Z","timestamp":1600212907000},"page":"1-11","source":"Crossref","is-referenced-by-count":3,"title":["Underground Communications Using Capacitive Data Transfer Devices"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6192-5769","authenticated-orcid":true,"given":"Shaoge","family":"Zang","sequence":"first","affiliation":[{"name":"Department of Electrical, Computer, and Software Engineering, The University of Auckland, 1010, New Zealand"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1094-2555","authenticated-orcid":true,"given":"Keran","family":"Hou","sequence":"additional","affiliation":[{"name":"Department of Electrical, Computer, and Software Engineering, The University of Auckland, 1010, New Zealand"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4527-0082","authenticated-orcid":true,"given":"Sing Kiong","family":"Nguang","sequence":"additional","affiliation":[{"name":"Department of Electrical, Computer, and Software Engineering, The University of Auckland, 1010, New Zealand"}]}],"member":"311","reference":[{"first-page":"1","volume-title":"Chapter 1 - introduction and overview of underground sensing for sustainable response","year":"2018","key":"1"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.adhoc.2006.04.003"},{"key":"3","first-page":"9","volume":"66","year":"2002","journal-title":"Soil Science Society of America Journal"},{"key":"4","series-title":"Lecture Notes in Computer Science","first-page":"231","volume-title":"Empirical evaluation of wireless underground-to- underground communication in wireless underground sensor networks","year":"2009"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2010.2048858"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/TIM.2015.2498918"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2019.2902646"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2011.093011.110632"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/MAP.2015.2453917"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/JESTPE.2019.2942034"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.3390\/en10111752"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/TIA.2020.2979110"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1049\/iet-pel.2018.5279"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2019.2935209"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2006.885073"},{"issue":"3, article 0320","key":"21","volume":"59","year":"2016","journal-title":"Annals of Geophysics"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1049\/iet-pel.2013.0749"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2020\/8849618.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2020\/8849618.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2020\/8849618.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,9,15]],"date-time":"2020-09-15T23:35:09Z","timestamp":1600212909000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/js\/2020\/8849618\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,9,15]]},"references-count":17,"alternative-id":["8849618","8849618"],"URL":"https:\/\/doi.org\/10.1155\/2020\/8849618","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"type":"print","value":"1687-725X"},{"type":"electronic","value":"1687-7268"}],"subject":[],"published":{"date-parts":[[2020,9,15]]}}}
