Built with ultra‑thin film layers and nanometre pressure‑sensitive materials, this linear pressure sensing element converts applied force directly into resistance changes for simple analog measurement. The elongated sensing area enables distributed force detection along beds, footwear, seats, or structural surfaces where conventional point sensors fall short. Fast response performance supports both static load monitoring and dynamic pressure measurement, making this flexible pressure detection module suitable for interactive systems, medical monitoring solutions, and embedded electronics requiring compact, lightweight sensing components.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e400mm Long Flexible Sensing Area\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe extended 400mm sensing length allows pressure monitoring across a wide linear area rather than a single contact point. This long strip design supports applications such as bed occupancy detection, gait monitoring inside footwear, and distributed force sensing in robotics or furniture systems. The thin and bendable structure enables installation on curved or flexible surfaces without affecting performance, providing reliable pressure detection along mattresses, insoles, cushions, or structural edges.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHigh‑Speed Static and Dynamic Pressure Detection\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe resistive pressure sensing structure responds rapidly to applied force with an activation time below 0.01 seconds and response time under 10ms. Such performance enables detection of both continuous loads and dynamic interactions up to 10Hz. Force intensity and frequency changes can therefore be recorded for behavioral analysis, smart interaction systems, or motion‑triggered electronics where real‑time pressure feedback is required.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eUltra‑Thin Film Structure with Nanometre Pressure Layer\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe sensing strip is constructed from ultra‑thin films with conductive circuits and nanometre pressure‑sensitive layers laminated together using double‑sided adhesive. When external force is applied to the active region, conductive paths connect through the pressure layer, causing resistance to decrease as pressure increases. This thin‑film architecture delivers durability, flexibility, and long operational life exceeding one million actuations while maintaining stable electrical characteristics.\u003c\/p\u003e\n\u003cp\u003e\u003cimg\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E37028-content1.webp?v=1791415770\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eFigure: RP-L-400 Dimension Diagram\u003c\/p\u003e\n\u003cp\u003e\u003cimg\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E37028-content2.webp?v=1791415783\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eFigure: Force vs Resistance\u003c\/p\u003e\n\u003cp\u003eSuch thin‑film force sensing technology is widely used in pressure switches, bed monitoring systems, intelligent footwear, medical sensing equipment, and interactive embedded electronics requiring lightweight linear pressure detection.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e400mm long flexible pressure sensing strip\u003c\/li\u003e\n\u003cli\u003eUltra‑thin structure with only 0.35mm thickness\u003c\/li\u003e\n\u003cli\u003eDetects both static and dynamic pressure signals\u003c\/li\u003e\n\u003cli\u003eFast activation time \u0026lt;0.01s and response time \u0026lt;10ms\u003c\/li\u003e\n\u003cli\u003eResistance decreases as applied pressure increases\u003c\/li\u003e\n\u003cli\u003eCapable of measuring force intensity and frequency\u003c\/li\u003e\n\u003cli\u003eFlexible film structure suitable for curved surfaces\u003c\/li\u003e\n\u003cli\u003eDurable design with lifespan \u0026gt;1 million actuations\u003c\/li\u003e\n\u003cli\u003eNo EMI or EDS generation during operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBed monitoring and occupancy detection systems\u003c\/li\u003e\n\u003cli\u003eSmart footwear and gait analysis\u003c\/li\u003e\n\u003cli\u003eMedical pressure monitoring equipment\u003c\/li\u003e\n\u003cli\u003ePressure‑activated switches\u003c\/li\u003e\n\u003cli\u003eInteractive furniture or seating systems\u003c\/li\u003e\n\u003cli\u003eRobotics force detection\u003c\/li\u003e\n\u003cli\u003eEmbedded human‑machine interaction projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThickness: 0.35mm\u003c\/li\u003e\n\u003cli\u003eTrigger Force: \u0026lt;20g, triggered (default resistance\u0026lt;200kΩ)\u003c\/li\u003e\n\u003cli\u003ePressure Measuring Range: 20g~10kg or larger\u003c\/li\u003e\n\u003cli\u003eStatic Pressure \u0026amp; Dynamic Pressure Measurement (within the frequency of 10Hz)\u003c\/li\u003e\n\u003cli\u003eInitial Resistance: \u0026gt;10MΩ\u003c\/li\u003e\n\u003cli\u003eActivation Time: \u0026lt;0.01S\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40℃~+85℃\u003c\/li\u003e\n\u003cli\u003eLifespan: \u0026gt;1million times\u003c\/li\u003e\n\u003cli\u003eHysteresis: +10%，(RF+ -RF-)\/FR+，1000g Force\u003c\/li\u003e\n\u003cli\u003eResponse Time: \u0026lt;10ms\u003c\/li\u003e\n\u003cli\u003eEMI: Not generate\u003c\/li\u003e\n\u003cli\u003eEDS: Not generate\u003c\/li\u003e\n\u003cli\u003eDrift: \u0026lt;5%, 2.5Kg Force, Static load 24H\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRP-L-400 Thin Film Pressure Sensor x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/wiki.dfrobot.com\/sen0299\/\" target=\"_blank\"\u003eProduct Wiki\u003c\/a\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":67585516568653,"sku":"E37028-001","price":17.83,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E37028-win1.jpg?v=1791415797","url":"https:\/\/www.mlab.com.au\/products\/rp-l-400-thin-film-pressure-sensor-strip-400mm-20g-10kg","provider":"MLAB","version":"1.0","type":"link"}
