Abstract

Official abstract text for this publication.

A gripping force measurement device includes a body portion and a plurality of pressure sensors. The plurality of pressure sensors includes at least one first sensor and two or more second sensors including pressure-sensitive surfaces oriented in the same direction. A pressure-sensitive surface of the first sensor and the pressure-sensitive surfaces of the two or more second sensors are disposed such that, when a subject pressurizes the pressure-sensitive surface of the first sensor and the pressure-sensitive surfaces of the two or more second sensors, the gripping force measurement device is grippable by the subject.

First claim

Opening claim text (preview).

The invention claimed is: 1. A gripping force measurement device comprising: a body portion; and a plurality of pressure sensors held by the body portion, wherein the plurality of pressure sensors includes a first sensor that is at least one pressure sensor, and two or more second sensors other than the first sensor, the two or more second sensors including pressure-sensitive surfaces oriented in a direction different from the pressure-sensitive surface of the first sensor, a pressure-sensitive surface of the first sensor and the pressure-sensitive surfaces of the two or more second sensors are disposed such that, when a subject pressurizes the pressure-sensitive surface of the first sensor and the pressure-sensitive surfaces of the two or more second sensors, the gripping force measurement device is grippable by the subject, and the body portion holds the first sensor slidable in a first specified range, and holds the second sensors slidable in a second specified range. 2. The gripping force measurement device according to claim 1 , further comprising a plate-like guide portion provided in the body portion, and configured to come into contact with a fingertips of the subject to guide positions of fingers with respect to the pressure-sensitive surface of at least one of the two or more second sensors. 3. The gripping force measurement device according to claim 1 , wherein the body portion includes a plurality of buttons for pressurizing the plurality of pressure sensors; and among the plurality of buttons, a button for pressurizing the pressure-sensitive surface of the first sensor and a button for pressurizing at least one of the pressure-sensitive surfaces of the two or more second sensors protrude outward from the body portion. 4. The gripping force measurement device according to claim 2 , wherein the body portion includes a plurality of buttons for pressurizing the plurality of pressure sensors; and among the plurality of buttons, a button for pressurizing the pressure-sensitive surface of the first sensor and a button for pressurizing at least one of the pressure-sensitive surfaces of the two or more second sensors protrude outward from the body portion. 5. The gripping force measurement device according to claim 1 , wherein the body portion is configured such that a distance between the first sensor and the two or more second sensors is changeable. 6. The gripping force measurement device according to claim 2 , wherein the body portion is configured such that a distance between the first sensor and the two or more second sensors is changeable. 7. The gripping force measurement device according to claim 3 , wherein the body portion is configured such that a distance between the first sensor and the two or more second sensors is changeable. 8. The gripping force measurement device according to claim 4 , wherein the body portion is configured such that a distance between the first sensor and the two or more second sensors is changeable.
