Utilizing the same physical mechanism for power and communication is critical for implant miniaturization. For the first time, we designed and demonstrated near-zero power magnetoelectric backscatter from mm-sized implants by exploiting the converse magnetostriction effects. The prototype system consists of an 8.2-mm3 wireless implant integrating an application-specific integrated circuit (ASIC) that achieves frequency-shift-keying backscattering via capacitive load modulation and a custom transceiver demodulating data through frequency-to-digital conversion. The magnetoelectric backscatter archives &gt; 1 kbps data rate at the 335-kHz carrier frequency, with a communication distance greater than 2 cm and a bit error rate (BER) less than 1E-3.<\/jats:p>","DOI":"10.1145\/3599184.3599192","type":"journal-article","created":{"date-parts":[[2023,5,22]],"date-time":"2023-05-22T23:52:21Z","timestamp":1684799541000},"page":"23-27","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Magnetoeletric Backscatter Communication for Millimeter-Sized Wireless Biomedical Implants"],"prefix":"10.1145","volume":"27","author":[{"given":"Zhanghao","family":"Yu","sequence":"first","affiliation":[{"name":"Rice University, Houston, TX, USA"}]},{"given":"Fatima T.","family":"Alrashdan","sequence":"additional","affiliation":[{"name":"Rice University, Houston, TX, USA"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Rice University, Houston, TX, USA"}]},{"given":"Matthew","family":"Parker","sequence":"additional","affiliation":[{"name":"Rice University, Houston, TX, USA"}]},{"given":"Xinyu","family":"Chen","sequence":"additional","affiliation":[{"name":"University of Michigan, Ann Arbor, MI, USA"}]},{"given":"Frank Y.","family":"Chen","sequence":"additional","affiliation":[{"name":"SambaNova Systems"}]},{"given":"Joshua","family":"Woods","sequence":"additional","affiliation":[{"name":"Rice University, Houston, TX, USA"}]},{"given":"Zhiyu","family":"Chen","sequence":"additional","affiliation":[{"name":"Rice University, Houston, TX, USA"}]},{"given":"Jacob T.","family":"Robinson","sequence":"additional","affiliation":[{"name":"Rice University, Houston, TX, USA"}]},{"given":"Kaiyuan","family":"Yang","sequence":"additional","affiliation":[{"name":"Rice University, Houston, TX, USA"}]}],"member":"320","published-online":{"date-parts":[[2023,5,22]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"Robinson","author":"Singer Amanda","year":"2020","unstructured":"Amanda Singer , Shayok Dutta , Eric Lewis , Ziying Chen , Joshua C.
