    Abstract: Provided is a biometric information measurement device that can detect a change in the biometric information of a wearer (a movement of a finger, the bending and stretching of an arm or foot, a posture change during sitting, a change in length of the body surface due to respiration, and a change in surface moisture amount). The present invention relates to a biometric information measurement device that is made of a fiber base material including a sensing member, and that is disposed in contact with a prescribed position of a living body, wherein the sensing member has at least two core-sheath structure threads in which high-resistance fibers as a cladding material are disposed around a linear conductor as a core material, two among the at least two core-sheath structure threads are disposed adjacent to each other to make it possible to read a change in resistance and/or a change in capacitance between the linear conductors of the two core-sheath structure threads, and the biometric information or a fluctuation thereof is measured based on said change. The present invention also relates to a garment provided with said device.

    Abstract: Provided are a polylactide-grafted cellulose nanofiber that is suitable as a molding material, and a production method thereof. A polylactide-grafted cellulose nanofiber includes grafted cellulose having a graft chain bonding to cellulose constituting a cellulose nanofiber, wherein the graft chain is a polylactide, and a ratio of an absorbance derived from C=O of the polylactide to an absorbance derived from O-H of the cellulose on an infrared absorption spectrum is no less than 0.01 and no greater than 1,000. In addition, a production method of a polylactide-grafted cellulose nanofiber includes carrying out graft polymerization of a lactide to cellulose constituting a cellulose nanofiber in the presence of an organic polymerization catalyst which includes an amine and a salt obtained by reacting the amine with an acid. As the organic polymerization catalyst, 4-dimethylaminopyridine and 4-dimethylaminopyridinium triflate are preferred.
