The pen to quantify human tremor of the wrist joint

摘要

The pen to quantify human tremor of the wrist joint. The present invention is designed considering an architecture simple and noninvasive to the user, ideal for the collection of signs of human tremor of the wrist joint by means of spelling.Through the device designed to capture the tremor in the spelling, it is possible to detect changes that occurred during the implementation of the minimum activity and those deriving from the tremor intrinsic to the individual who use the device.The present invention is composed of a common ballpoint pen, motion sensor associated with the end portion of the pen, to capture any movement of the same through the movement of the wrist joint in spellings. Communication cables, to communicate the motion sensor, a microcontroller, and the microcontroller to communicate a hard disk for later analysis by means of a software.The microcontroller is adjusted to the arm of the individual to process information obtained through the motion sensors. The software for the acquisition of signals receives the information through the microcontroller and generates the signals captured by the motion sensor. A battery to power the system and thus isolated from the mains and placed in a strategic location on the individual.
