However, soft-sensor-based wearable dynamic measurement has not been well achieved. In this paper, the dynamic measurements of legs were investigated by using dielectric elastomers as stain sensors, and an alternating signal was applied to detect the dynamic rotational angles of the legs. To realize a quick response, parameters of the sensors were optimized by circuit analysis. The sensor can detect hip, knee, and ankle joint motions with a sample frequency of 200\u2009Hz. The measurements of the sensors were compared with a commercial motion capture system from PhaseSpace, and dynamic errors between them were smaller than 3\u00b0 when squatting and walking at low speed and smaller than 5\u00b0 when walking at high speed. Experiments therefore demonstrate the feasibility of the integrated wearable stretch sensors with pants.<\/jats:p>","DOI":"10.1155\/2020\/9231571","type":"journal-article","created":{"date-parts":[[2020,2,15]],"date-time":"2020-02-15T18:30:58Z","timestamp":1581791458000},"page":"1-10","source":"Crossref","is-referenced-by-count":12,"title":["Dynamic
