In order to clarify the principle of preparation,sensing properties and applications of textilebased flexible mechanical sensors,the most recent progress of textile-based flexible mechanical sensors were described,including fabrication,properties and applications.The novelty and advantages of textilebased piezoresistive and capacitive sensors in the field of human-activity monitoring,personal healthcare and user interface were investigated.The results indicate that the sensors with one-dimensional fibrous and two-dimensional fabric structures are main structures,and the sensors with tunable substrates and devisable combinations exhibite remarkable sensing properties（linearity,non-hysteresis,repeatability,sensitivity and durability）.The textile-based flexible mechanical sensors with high electrical conductivity,sensitivity and durability are the most desirable properties in the near future.
