Increasing　sensitivity,　measuring　points,　and　stability　have　always　been　the　pursuit　of　sensors.　ZnSe9:CO1　and　Ag　composite　nano　films　were　coated　on　polarization　maintaining　fiber　(PMF).　Then,　the　coated　PMF　was　nested　in　capillary　and　hose　which　was　encapsulated　with　polydimethylsiloxane　(PDMS)　and　epoxy　resin.　The　integrated　capillary　sensor　and　thermoplastic　hose　sensor　were　prepared.　The　gradient　sensitization　of　various　measurement　parameters　such　as　temperature,　stress,　and　micro　bending　is　realized.　The　temperature　sensitivity　is　1.49　nm/degrees　C,　the　micro　bending　sensitivity　is　1.72　nm/10(2)　g,　and　the　stress　sensitivity　is　6.27　nm/m　epsilon.　The　sensors　maintain　good　linearity　and　instantaneous　response　while　having　high　sensitivity.　By　adjusting　the　length　of　PMF,　the　number　of　troughs　is　increased　in　the　same　band　range,　and　different　troughs　have　different　sensitivities,　which　solves　the　inherent　problem　of　cross　sensitivity　and　realizes　multiparameter　measurement.　Capillary　sensors　are　used　for　remote　safe　real-time　monitoring　of　mechanical　overheating,　and　hose　sensors　are　used　for　real-time　monitoring　of　bridge　load　and　human　joint　bending.　This　work　is　of　great　significance　to　the　extension　of　the　application　range　of　optical　fiber　sensor.
