HNSWs are mechanical waves that can form and travel in highly nonlinear systems, such as granular particles in Hertzian contact. The easiest setup consists of a built-in transducer in drypoint contact with the structure or material to be inspected\/monitored. The transducer is made of a monoperiodic array of spherical particles that enables the excitation and detection of the solitary waves. The transducer is wired to a data acquisition system that controls the functionality of the transducer and stores the time series for post-processing. In this paper, the design and testing of a wireless unit that enables the remote control of a transducer without the need to connect it to sophisticated test equipment are presented. Comparative tests and analyses between the measurements obtained with the newly designed wireless unit and the conventional wired configuration are provided. The results are corroborated by an analytical model that predicts the dynamic interaction between solitary waves and materials with different modulus. The advantages and limitations of the proposed wireless platform are given along with some suggestions for future developments.<\/jats:p>","DOI":"10.3390\/s20113016","type":"journal-article","created":{"date-parts":[[2020,5,28]],"date-time":"2020-05-28T12:36:58Z","timestamp":1590669418000},"page":"3016","update-policy":"https:\/\/2.zoppoz.workers.dev:443\/https\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Wireless Module for Nondestructive Testing\/Structural Health Monitoring Applications Based on Solitary Waves"],"prefix":"10.3390","volume":"20","author":[{"given":"Ritesh","family":"Misra","sequence":"first","affiliation":[{"name":"Mixed-Signal Multi-Domain Systems Laboratory, Department of Electrical and Computer Engineering, University of Pittsburgh, 3700 O\u2019Hara Street, 1206 Benedum Hall, Pittsburgh, PA 15261, USA"}]},{"ORCID":"https:\/\/2.zoppoz.workers.dev:443\/https\/orcid.org\/0000-0002-8770-2376","authenticated-orcid":false,"given":"Hoda","family":"Jalali","sequence":"additional","affiliation":[{"name":"Laboratory for Nondestructive Evaluation and Structural Health Monitoring Studies, Department of Civil and Environmental Engineering, University of Pittsburgh, 3700 O\u2019Hara Street, 729 Benedum Hall, Pittsburgh, PA 15261, USA"}]},{"ORCID":"https:\/\/2.zoppoz.workers.dev:443\/https\/orcid.org\/0000-0003-2281-5115","authenticated-orcid":false,"given":"Samuel J.","family":"Dickerson","sequence":"additional","affiliation":[{"name":"Mixed-Signal Multi-Domain Systems Laboratory, Department of Electrical and Computer Engineering, University of Pittsburgh, 3700 O\u2019Hara Street, 1206 Benedum Hall, Pittsburgh, PA 15261, USA"}]},{"ORCID":"https:\/\/2.zoppoz.workers.dev:443\/https\/orcid.org\/0000-0002-7159-2221","authenticated-orcid":false,"given":"Piervincenzo","family":"Rizzo","sequence":"additional","affiliation":[{"name":"Laboratory for Nondestructive Evaluation and Structural Health Monitoring Studies, Department of Civil and Environmental Engineering, University of Pittsburgh, 3700 O\u2019Hara Street, 729 Benedum Hall, Pittsburgh, PA 15261, USA"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"733","DOI":"10.1007\/BF00905892","article-title":"Propagation of nonlinear compression pulses in granular media","volume":"24","author":"Nesterenko","year":"1984","journal-title":"J.
