Abstract

According to an aspect, a detection device includes: a force sensor disposed at a mouthpiece; a myoelectric sensor attachable to a human cheek; and a controller configured to perform output in which an output of the force sensor is synchronized with an output of the myoelectric sensor.

First claim

What is claimed is:

1 . A detection device comprising:
a force sensor disposed at a mouthpiece; a myoelectric sensor attachable to a human cheek; and a controller configured to perform output in which an output of the force sensor is synchronized with an output of the myoelectric sensor.

2 . The detection device according to claim 1 , wherein
a plurality of force sensors are disposed at the mouthpiece, and the controller outputs data in which outputs of the force sensors are individually identifiable.

3 . The detection device according to claim 1 , wherein
the force sensor is disposed at a flexible substrate, and the flexible substrate is mounted on the mouthpiece.

4 . The detection device according to claim 3 , wherein the flexible substrate is adhesively fixed such that a gap is formed between the flexible substrate and the mouthpiece, inside the mouthpiece.

5 . The detection device according to claim 1 , wherein
the myoelectric sensor includes an electrode, and gel and double-sided tape are applied on an attachment surface of the myoelectric sensor that is provided with the electrode.

6 . The detection device according to claim 5 , wherein
the controller
causes the myoelectric sensor to operate at a first cycle until the output of the myoelectric sensor exceeds a first threshold, and
causes the myoelectric sensor to operate at a second cycle after the output of the myoelectric sensor exceeds the first threshold, and
the second cycle is a higher-frequency cycle than the first cycle.

7 . The detection device according to claim 5 , wherein
the controller
causes the force sensor to operate at a third cycle until the output of the force sensor exceeds a second threshold, and
causes the force sensor to operate at a fourth cycle after the output of the force sensor exceeds the second threshold, and
the fourth cycle is a higher-frequency cycle than the third cycle.

8 . The detection device according to claim 5 , further comprising a communication circuit configured to communicate with an external apparatus, wherein
the controller
does not cause the communication circuit to operate when neither a first condition nor a second condition is satisfied, and
causes the communication circuit to operate when at least one of the first condition and the second condition is satisfied,
the first condition is that the output of the myoelectric sensor exceeds a first threshold, and the second condition is that the output of the force sensor exceeds a second threshold.

9 . The detection device according to claim 1 , further comprising a display configured to perform display output in which the output of the force sensor is synchronized with the output of the myoelectric sensor.
