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.
Claims13
A neck movement measuring device comprising:
- a sensor sheet;
- a displacement sensor disposed on the sensor sheet and configured to be attached to a neck of a subject;
- and
- a controller configured to:
- set a reference value based on a measured value of the displacement sensor and after a set time period elapses since a power supply of the neck movement measuring device is turned on, and
- output a displacement amount relative to the reference value as a measurement result of the displacement sensor,
- wherein the displacement sensor comprises a plurality of displacement sensors that each are electrical conductors formed of a material with a resistance configured to change as each respective displacement sensor expands and contracts.
A neck movement measuring device comprising:
- a sensor sheet;
- a displacement sensor disposed on the sensor sheet and configured to be attached to a neck of a subject;
- and
- a controller configured to:
- set a reference value based on a measured value of the displacement sensor, and
- output a displacement amount relative to the reference value as a measurement result of the displacement sensor,
- wherein the displacement sensor comprises a plurality of displacement sensors that each are electrical conductors formed of a material with a resistance configured to change as each respective displacement sensor expands and contracts, and
- wherein the reference value is a greatest value of measured values of the displacement sensor measured during a predetermined time period.
A neck movement measuring device comprising:
- a sensor sheet;
- a displacement sensor disposed on the sensor sheet and configured to be attached to a neck of a subject;
- and
- a controller configured to:
- set a reference value based on a measured value of the displacement sensor, and
- output a displacement amount relative to the reference value as a measurement result of the displacement sensor,
- wherein the displacement sensor comprises a plurality of displacement sensors that each are electrical conductors formed of a material with a resistance configured to change as each respective displacement sensor expands and contracts,
- wherein the controller is configured to output the displacement amount that indicates a masticatory movement as neck movement of the subject wearing the neck movement measuring device, and
- wherein the controller is configured to detect the masticatory movement as the neck movement when an absolute value of the displacement amount relative to the reference value is greater than or equal to a predetermined first threshold and smaller than a predetermined second threshold that is greater than the first threshold.
