Title
(EN) BENDING ANGLE MEASURING SENSOR
(FR) CAPTEUR DE MESURE D'ANGLE DE FLEXION
(RU) ДАТЧИК ИЗМЕРЕНИЯ УГЛОВ СГИБА
Abstract
(EN) The present sensor can be used in devices for restoring manual dexterity in the case of motor impairments to monitor the recovery process, and also for working in virtual or augmented reality. The technical result consists in improving the sensitivity of a sensor and providing for highly accurate bending angle measurement. A bending angle measuring sensor comprises a sensing element, a transducer, and a reading module capable of detecting an electrical change. The sensing element comprises two capacitors, each of which consists of three elastic layers, i.e. two electrodes and a dielectric disposed therebetween, each of the electrodes being made of a thermosetting plastic with carbon nanotubes homogeneously distributed throughout the volume thereof. The transducer comprises a switch, a precision comparator, a microcontroller, a clock generator, the frequency of which is temperature stabilized, a low-noise temperature-compensated voltage reference, and a current source. The reading module, in the form of an accessory, is configured to transmit measuring results to a computer or to a mobile device over a wireless interface and also to power the measuring transducer.
(FR) Ce capteur peut être utilisé dans des dispositifs de restauration de l'habileté des bras en cas de troubles moteurs, lors du contrôle du processus de réhabilitation ainsi que lors de l'utilisation avec la réalité virtuelle ou augmentée. Le résultat technique consiste en une augmentation de la sensibilité et une plus grande précision de mesure de l'angle de flexion. Ce capteur de mesure d'angles de flexion comprend un élément sensible, un convertisseur et un module informatique capable de détecter un changement électrique. L'élément sensible comprend deux condensateurs qui comprennent chacun trois couches élastiques: deux électrodes et un diélectrique disposé entre elles; chaque électrode se compose d'une résine thermodurcissable comprenant des nanotubes de carbone homogénéisés en termes de volume. Le convertisseur comprend un commutateur, un comparateur de précision, un microcontrôleur, un générateur d'horloge avec une stabilisation en température de la fréquence, une source à faible bruit de tension de référence avec compensation en température et une source de courant. Le module informatique sous forme d'accessoire peut transmettre des résultats de mesures à un ordinateur ou à un dispositif mobile via une interface sans fil, et peut alimenter le convertisseur de mesure.
(RU) Датчик может применяться в устройствах для восстановления мелкой моторики рук при двигательных нарушениях, при контроле реабилитационного процесса, а также для работы с виртуальной или дополненной реальностью. Технический результат заключается в обеспечении повышенной чувствительности датчика и высокой точности измерения углов сгиба. Датчик измерения углов сгиба содержит чувствительный элемент, преобразователь и считывающий модуль, выполненный с возможностью обнаружения электрического изменения. Чувствительный элемент содержит два конденсатора, каждый из которых состоит из трех эластичных слоев: двух электродов и расположенного между ними диэлектрика, каждый электрод выполнен из реактопласта с гомогенизированными по объему углеродными нанотрубками. Преобразователь содержит коммутатор, прецизионный компаратор, микроконтроллер, тактовый генератор с температурной стабилизацией частоты, малошумящий источник опорного напряжения с температурной компенсацией и источник тока. Считывающий модуль в виде гарнитуры выполнен с возможностью передачи результатов измерений на компьютер или мобильное устройство по беспроводному интерфейсу, а также с возможностью питания измерительного преобразователя.
