  • Publication number: 20240085256
    Abstract: A load sensor is configured to detect, as change in capacitance, change, in a contact area between an electrically-conductive elastic body and a dielectric body, that occurs due to a load applied to an upper face of the load sensor. In the load sensor, a plurality of sensor parts each configured to detect the load are disposed so as to be arranged in a plane direction, and a buffer part configured to suppress displacement of the upper face due to the load applied to a first sensor part from being propagated to a second sensor part adjacent to the first sensor part is disposed between the first sensor part and the second sensor part.

  • Patent number: 11298372
    Abstract: The present invention provides novel compositions for suppressing or improving hair loss, and compositions for suppressing or improving graying. More specifically, it provides agents that stabilize type XVII collagen expression, preferably agents that suppress the degradation of type XVII collagen by ELANE inhibitors and such, and compositions comprising a DNA repair-promoting agent or a DNA damage-suppressing agent as an active ingredient. Advantageous suppressive effects of hair loss and graying can be obtained when a composition comprising as an active ingredient a suppressive agent of type XVII collagen degradation such as an ELANE inhibitor is administered to a mammal. For the ELANE inhibitors, suppressive agents of type XVII collagen degradation and DNA repair-promoting agents, low-molecular compounds, polypeptides, proteins, antibodies, or nucleic acid medicine such as antisense oligos or siRNAs may be used.
