Title (EN) PCB-BASED GAUGE SYSTEM
(FR) SYSTÈME DE JAUGE BASÉ SUR UNE CARTE DE CIRCUIT IMPRIMÉ
Abstract:
(EN) A force sensor integrated directly into a printed circuit board (PCB) is provided that utilizes standard PCB manufacturing techniques. Traces on the PCB are arranged such that as a force is exerted on or imparted to the board, the inductance of the circuit changes, thereby causing a shift in the resonant frequency. The shift in resonant frequency may be correlated to the force such that the PCB functions as a force gauge. Signal conditioning and processing circuitry, including non- volatile memory for storage of calibration data, may be located on the same PCB as the sensor functionality. The disclosed force sensor is low cost, requires no connector, has a low profile, reduces variation due to assembly of separate components, is easy to calibrate, and is easily modified, prototyped, and manufactured to meet a variety of design criteria and commercial applications.
(FR) L'invention concerne un capteur de force intégré directement dans une carte de circuit imprimé (PCB) qui utilise des techniques de fabrication de PCB standard. Des tracés sur la PCB sont agencés de telle sorte que lorsqu'une force est exercée sur la carte ou communiquée à celle-ci, l'inductance du circuit change, ce qui provoque un décalage dans la fréquence de résonance. Le décalage de fréquence de résonance peut être corrélé à la force de telle sorte que la PCB fonctionne comme une jauge de force. Des circuits de traitement et de conditionnement de signal, comprenant une mémoire non volatile pour le stockage de données d'étalonnage, peuvent être situés sur la même PCB que la fonctionnalité de capteur. Le capteur de force de l'invention est peu coûteux, ne nécessite pas de connecteur, est peu encombrant, réduit les variations dues à l'assemblage de composants séparés, est facile à étalonner et est facilement modifié, prototypé et fabriqué pour satisfaire à divers critères de conception et à diverses applications commerciales.
