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.

Object: To provide a pressure sensor that can provide a reduced sensation of a foreign body and that has a good sensitivity to pressure from a low load region to a high load region. Resolution means: The pressure sensor includes a variable resistor and a plurality of electrodes. The variable resistor is made of an electrically conductive foam elastomer material. The electrically conductive foam elastomer material is a material imparted with electrical conductivity by dispersing electrically conductive fillers into an elastomer material and obtained by foaming the elastomer material. The plurality of electrodes are disposed at intervals from each other on one surface in contact with the variable resistor.

A pressure sensor includes a variable resistance portion, and a first electrode and a second electrode. The variable resistance portion includes a conductive foam elastomer material. When pressure is applied to the variable resistance portion, the variable resistance portion is compressed in accordance with the pressure. As the compression amount increases, the electric resistance of the variable resistance portion decreases. The first electrode and the second electrode are configured to contact with the variable resistance portion at a location having an interval of 0.5 mm or greater with each other, therefore being electrically connected via the variable resistance portion.

A pressure sensor includes: a base including an outer surface partially or entirely composed of a curved surface; a plurality of electrodes disposed on the outer surface of the base with spaces therebetween and including at least one signal electrode and at least one ground electrode; and at least one variable resistor made from conductive foam elastomer material and configured to be elastically compressed upon application of pressure and such that electric resistance between the signal electrode and the ground electrode decreases as the amount of the compression increases.

A measurement information output system comprises an input unit and an output unit. The input unit is configured to input, to an arithmetic unit, a detected force value indicating the magnitude of force detected by one or more force sensors arranged so as to receive impact by motion of a measurement target and a detected acceleration value indicating the acceleration of the measurement target detected by an acceleration sensor arranged so as to detect the acceleration of the measurement target. The arithmetic unit is configured to compute the weight of the measurement target on the basis of the detected force value and the detected acceleration value. The output unit is configured to output, as a measured weight value, the weight of the measurement target computed by the arithmetic unit.
