In this study, a design and optimization for a new XYZ micropositioner are developed to obtain three same displacements in three axes. The proposed micropositioner is a planar mechanism whose advantage is a generation of three motions with only two actuators. In the design strategy, the proposed micropositioner is designed by a combination of a symmetrical four-lever displacement amplifier, a symmetrical parallel guiding mechanism, and a symmetrical parallel redirection mechanism. The Z-shaped hinges are used to gain motion in the Z-axis displacement. Four flexure right-circular hinges are combined with two rigid joints and two flexure leaf hinges to permit two large X-and-Y displacements. The symmetrical four-lever displacement amplifier is designed to increase the micropositioner\u2019s travel. The displacement sensor is built by embedding the strain gauges on the hinges of the micropositioner, which is developed to measure the travel of the micropositioner. The behaviors and performances of the micropositioner are modeled by using the Taguchi-based response surface methodology. Additionally, the geometrical factors of the XYZ micropositioner are optimized by teaching\u2013learning-based optimization. The optimized design parameters are defined with an A of 0.9 mm, a B of 0.8 mm, a C of 0.57 mm, and a D of 0.7 mm. The safety factor gains 1.85, while the displacement achieves 515.7278 \u00b5m. The developed micropositioner is a potential option for biomedical sample testing in a nanoindentation system.<\/jats:p>","DOI":"10.3390\/s22218204","type":"journal-article","created":{"date-parts":[[2022,10,26]],"date-time":"2022-10-26T09:59:37Z","timestamp":1666778377000},"page":"8204","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Design and Optimization for a New XYZ Micropositioner with Embedded Displacement Sensor for Biomaterial Sample Probing Application"],"prefix":"10.3390","volume":"22","author":[{"given":"Minh Phung","family":"Dang","sequence":"first","affiliation":[{"name":"Faculty of Mechanical Engineering, Ho Chi Minh City University of Technology and Education, Ho Chi Minh City, Vietnam"}]},{"given":"Hieu Giang","family":"Le","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Ho Chi Minh City University of Technology and Education, Ho Chi Minh City, Vietnam"}]},{"given":"Thu Thi Dang","family":"Phan","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Thu Duc College of Technology, Thu Duc City, Ho Chi Minh City, Vietnam"}]},{"given":"Ngoc Le","family":"Chau","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Industrial University of Ho Chi Minh City, Ho Chi Minh City, Vietnam"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9165-4680","authenticated-orcid":false,"given":"Thanh-Phong","family":"Dao","sequence":"additional","affiliation":[{"name":"Division of Computational Mechatronics, Institute for Computational Science, Ton Duc Thang University, Ho Chi Minh City, Vietnam"},{"name":"Faculty of Electrical & Electronics Engineering, Ton Duc Thang University, Ho Chi Minh City, Vietnam"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"131","DOI":"10.1016\/j.mechmachtheory.2019.04.012","article-title":"Topology optimization of bistable mechanisms with maximized differences between switching forces in forward and backward direction","volume":"139","author":"Chen","year":"2019","journal-title":"Mech.
