Declarations under Rule 4.17: — of inventorship (Rule 4.17(iv)) Published: — with international search report (Art. 21(3)) — in black and white; the international application as filed contained color or greyscale and is available for download from PATENTSCOPE (54) Title: MICROTUBE SENSOR FOR PHYSIOLOGICAL MONITORING W O 20 18/ 160 135 Al (57) : A soft, flexible microtube sensor and associated method of sensing force are described. A liquid metallic alloy is sealed within a microtube as thin as a strand of human hair to form the physical force sensing mechanism. The sensor is hardly distinguishable with the naked eye, and can be used for the con- tinuous biomonitoring of physiological signals, such as unobtru- sive pulse monitoring. Also described is a method of fabricating the microtube sensor and wearable devices incorporating one or more microtube sensors.
