Abstract: A device may include a substrate which is configured to be stretchable and contractible and includes a major surface. A device may include a first wire and a second wire which are disposed on or in the major surface. A device may include in a plan view from a normal direction of the major surface, the substrate includes a sensing region which is configured to be stretchable and contractible in a first direction, and a first region and a second region that face each other in the first direction across the sensing region, the first wire and the second wire extend over the first region, the sensing region, and the second region; and the first wire and the second wire are electrically isolated from each other and are arranged in the sensing region at a distance from each other in a second direction that is orthogonal to the first direction.

Abstract: A temperature measurement device that includes: a tube; and a temperature sensor unit within the tube. The temperature sensor unit includes a flexible sheet and a plurality of temperature sensor elements on the flexible sheet.

Abstract: A laryngeal elevation measurement device is provided that includes first and second displacement sensors and a control unit. The first displacement sensor is attachable to a neck of a test subject. The second displacement sensor 22 attachable to a site that is part of the neck of the test subject and that is located at a predetermined distance from the first displacement sensor. The control unit acquires the displacement amounts of the first and second displacement sensors. The control unit estimates positional changes of the laryngeal prominence of the test subject based on changes over time in the displacement amount of the first displacement sensor and changes over time in the displacement amount of the second displacement sensor, and the predetermined distance. The control unit outputs a result of estimation.

Abstract: A displacement sensor that includes: a sensor unit including a base member having a first main surface and a second main surface opposite the first main surface, and a sensor sheet on the first main surface of the base member, the sensor sheet configured to measure a displacement amount of the base member; and a first cover sheet detachably attached to the sensor sheet on a side thereof opposite to the base member, wherein an elastic modulus of the first cover sheet is larger than an elastic modulus of the base member.

Abstract: A neck movement measuring device is provided that includes displacement sensors and a controller. The displacement sensors are formed as sheets attachable to the neck skin of a subject and measure the deformation amount. The controller receives measured values of the displacement sensors and sets a reference value based on measured values of the displacement sensor. In addition, the controller outputs the displacement amount relative to the reference value as a measurement result.

Abstract: An elastically deformable electrode that includes a plurality of electrode elements spaced from each other, and a liquid wire which is a liquid conductor configured to electrically connect the plurality of electrode elements. The electrode may also include a solid wire sealing the liquid wire, and an insulator between the solid wire and the plurality of electrode elements.

Abstract: A surface electrode having a first surface and a plurality of electrode elements disposed on the first surface and spaced from each other in a manner so as to be configured to contact a measured surface of an object to be measured; a stretchable wire electrically connecting the plurality of electrode elements; and a stretchable insulator covering a side of the stretchable wire adjacent to the electrode elements.
