In order to gather requirements for the design of such systems, long-term gait observation of the patients over the course of multiple days in an environment of daily living are required. In this paper a wearable all-in-one data acquisition system for collecting and storing biomechanical data in everyday life is proposed. The system is designed to be cost efficient and easy to use, using off-the-shelf components and a cloud server system for centralized data storage. The measurement accuracy of the system was verified, by measuring the angle of the human knee joint at walking speeds between 3 and 12 km\/h in reference to an optical motion analysis system. The acquired data were uploaded to a cloud database via a smartphone application. Verification results showed that the proposed toolchain works as desired. The system reached an RMSE from 2.9\u00b0 to 8\u00b0, which is below that of most comparable systems. The system provides a powerful, scalable platform for collecting and processing biomechanical data, which can help to automize the generation of an extensive database for human kinematics.<\/jats:p>","DOI":"10.3390\/s24082405","type":"journal-article","created":{"date-parts":[[2024,4,10]],"date-time":"2024-04-10T03:07:48Z","timestamp":1712718468000},"page":"2405","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["SensAA\u2014Design and Verification of a Cloud-Based Wearable Biomechanical Data Acquisition System"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-4991-6439","authenticated-orcid":false,"given":"Jonas Paul","family":"David","sequence":"first","affiliation":[{"name":"Zentrum f\u00fcr Zuverl\u00e4ssige Mechatronische Systeme (ZMS), Aalen University, 73430 Aalen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Schick","sequence":"additional","affiliation":[{"name":"Zentrum f\u00fcr Zuverl\u00e4ssige Mechatronische Systeme (ZMS), Aalen University, 73430 Aalen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorenz","family":"Rapp","sequence":"additional","affiliation":[{"name":"Zentrum f\u00fcr Zuverl\u00e4ssige Mechatronische Systeme (ZMS), Aalen University, 73430 Aalen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes","family":"Schick","sequence":"additional","affiliation":[{"name":"Zentrum f\u00fcr Zuverl\u00e4ssige Mechatronische Systeme (ZMS), Aalen University, 73430 Aalen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Glaser","sequence":"additional","affiliation":[{"name":"Zentrum f\u00fcr Zuverl\u00e4ssige Mechatronische Systeme (ZMS), Aalen University, 73430 Aalen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"81","DOI":"10.1007\/s00508-016-1096-4","article-title":"Gait disorders in adults and the elderly: A clinical guide","volume":"129","author":"Pirker","year":"2017","journal-title":"Wien.
