The capacitive sensor contains a polydimethylsiloxane (PDMS) dielectric layer with an array of electrodes. The sensor was designed in such a way that four components of glenohumeral contact forces can be quantified to help ensure proper soft tissue tensioning during the procedure. Fabricated using soft lithography, the sensor has a loading time of approximately 400 ms when a 14.13 kPa load is applied and has a sensitivity of 1.24 \u00d7 10\u22123 pF\/kPa at a load of 1649 kPa. A replica RTSA prothesis was 3D printed, and the sensor was mounted inside the humeral cap. Four static right shoulder positions were tested, and the results provided an intuitive graphical description of the pressure distribution across four quadrants of the glenohumeral joint contact surface. It may help clinicians choose a right implant size and offset that best fit a patient\u2019s anatomy and reduce postoperative biomechanical complications such as dislocation and stress fracture of the scapula.<\/jats:p>","DOI":"10.3390\/mi12111430","type":"journal-article","created":{"date-parts":[[2021,11,21]],"date-time":"2021-11-21T21:00:50Z","timestamp":1637528450000},"page":"1430","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Micromachined Tactile Sensor Array for RTSA"],"prefix":"10.3390","volume":"12","author":[{"given":"Elliott C.","family":"Leinauer","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering and Computer Science, University of Missouri, Columbia, MO 65201, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.
