A low-power, low-noise, and high-gain recording module was designed to acquire signal from an implantable flexible L-Glu sensor fabricated by micro-electro-mechanical system (MEMS)-based processes. The wearable recording module was wirelessly powered through inductive coupling transmitter antennas. Lateral and angular misalignments of the receiver antennas were resolved by using a multi-transmitter antenna configuration. The effective coverage, over which the recording module functioned properly, was improved with the use of in-phase transmitter antennas. Experimental results showed that the recording system was capable of operating continuously at distances of 4 cm, 7 cm and 10 cm. The wireless power management system reduced the weight of the recording module, eliminated human intervention and enabled animal experimentation for extended durations.<\/jats:p>","DOI":"10.3390\/s150924553","type":"journal-article","created":{"date-parts":[[2015,9,23]],"date-time":"2015-09-23T12:24:25Z","timestamp":1443011065000},"page":"24553-24572","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Wireless Power Transfer for Autonomous Wearable Neurotransmitter Sensors"],"prefix":"10.3390","volume":"15","author":[{"given":"Cuong","family":"Nguyen","sequence":"first","affiliation":[{"name":"Electrical Engineering Department, University of Texas at Arlington, TX 76019, USA"}]},{"given":"Pavan","family":"Kota","sequence":"additional","affiliation":[{"name":"Electrical Engineering Department, University of Texas at Arlington, TX 76019, USA"}]},{"given":"Minh","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Electrical Engineering Department, University of Texas at Arlington, TX 76019, USA"}]},{"given":"Souvik","family":"Dubey","sequence":"additional","affiliation":[{"name":"Electrical Engineering Department, University of Texas at Arlington, TX 76019, USA"}]},{"given":"Smitha","family":"Rao","sequence":"additional","affiliation":[{"name":"Electrical Engineering Department, University of Texas at Arlington, TX 76019, USA"}]},{"given":"Jeffrey","family":"Mays","sequence":"additional","affiliation":[{"name":"Electrical Engineering Department, University of Texas at Arlington, TX 76019, USA"}]},{"given":"J.-C.","family":"Chiao","sequence":"additional","affiliation":[{"name":"Electrical Engineering Department, University of Texas at Arlington, TX 76019, USA"}]}],"member":"1968","published-online":{"date-parts":[[2015,9,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1419","DOI":"10.1039\/a704508e","article-title":"Biosensor for neurotransmitter l-glutamic acid designed for efficient use of l-glutamate oxidase and effective rejection of interference","volume":"122","author":"Ryan","year":"1997","journal-title":"Analyst"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1200","DOI":"10.1021\/jp065747b","article-title":"Ferrocene functionalized single-walled carbon nanotube bundles.
