Abstract: Provided is a sensor capable of suppressing deviation in the state where the sensor is in contact with a living body. A sensor 1 converts, to an electrical signal, the amount of a substance to be measured contained in a secretion from a living body H, the sensor 1 comprising: a sensor main body 10 having an electrode part 11 that is disposed on the contact surface side contacting the living body H and a substrate 12 that is disposed on the exposed surface side opposite to the contact surface; and a fixing part 20 for fixing the sensor main body 10 to the living body H, wherein the fixing part 20 has a flexible sheet 21 that is attached to the living body H and fixes the sensor main body 10 to the living body H, and a spacer part 22 that is disposed between the flexible sheet 21 and the exposed surface and has a thickness equal to or thicker than that of the sensor main body 10.

Abstract: A wearable device according to an embodiment includes a detection unit, a first layer, a second layer, and a third layer. The detection unit detects the living body information. The first layer is flexible and disposed in a first direction relative to the detection unit and includes a conductor electrically connected to the detection unit. The second layer is disposed in the first direction relative to the first layer and is harder than the first layer. The third layer is disposed in the first direction relative to the second layer and includes an electronic component electrically connected to the conductor.

Abstract: An enzyme sensor is configured to measure a measurement target substance included in a secretion of a living body. The enzyme sensor includes a layered structure including (a) an absorber layer configured to absorb the secretion, (b) an enzyme layer containing an enzyme, and (c) an electrode part arranged in an order of the (a), the (b), and the (c). The absorber layer includes a polymeric material having a chemically bound crosslinked structure.

Abstract: An exercise assistance device includes a biological information acquisition unit, a storage unit, an exercise menu setting unit, and an exercise menu presentation unit. The biological information acquisition unit acquires, from a biosensor that measures a measurement target substance contained in a secretion from a living body, biological information indicating a result of such measurement by the biosensor. The storage unit stores the biological information. The exercise menu setting unit sets an exercise menu based on the biological information stored in the storage unit. The exercise menu presentation unit presents the exercise menu set by the exercise menu setting unit.

Abstract: The invention provides a protective plate and a display device that can suppress yellowing, reduce a cost, and keep glass from scattering. The invention is a protective plate including a glass substrate; a first layer laminated on a main surface on one side of the glass substrate; a second layer laminated on the first layer; and an antireflective film pasted on a main surface on the other side of the glass substrate, in which the first layer contains polyorganosiloxane (A) and metal oxide particles (B), the second layer contains polyorganosiloxane (C), the antireflective film contains an organic matter, and transmittance of a laminated body of the glass substrate, the first layer, and the second layer is 82% or less at a wavelength of 340 nm.
