1. System for measuring a palmar gripping force, comprising a device for measuring said palmar gripping force that comprises
a grip configured so as to receive a palmar griping force, a force sensor configured so as to measure said palmar gripping force, an electronic module integrated in the device and comprising at least one microcontroller connected to the sensor for processing data issuing from said sensor, wherein the system comprises a strain gauge for detecting forces from a zero or almost zero value, and which has a precision at a minimum of approximately 50 g for a range of measurements ranging from 0 to 90 kg, and/or a sensitivity of less than approximately 10 g, and the electronic module comprises means for performing the following actions: (a)—calibrating the sensor, in which: (a1)—the sensor receives a plurality of calibration forces, (a2)—establishing a linear calibration function from calibration points, a first coordinate of which is a sensor measurement and a second coordinate of which is the value of said calibration force, said calibration function being linear by segments, (b)—recording a palmar gripping force value according to a first coordinate of a point of the linear calibration function, and determining a calibrated force value corresponding to the second coordinate of said point of the linear calibration function. |
