Guanto Sensoriale con Sistema di recupero dell’energia Sensory glove with energy recovery system
DESCRIZIONE DESCRIPTION
Le mani dell'uomo sono fondamentali per interagire con l'ambiente circostante e per comunicare. Pertanto, la possibilità di misurare i movimenti delle mani e dita, può essere utile per una serie di applicazioni, come il riconoscimento del linguaggio dei segni, la riabilitazione motoria, per la valutazione del gesto chirurgico, ecc. La misura dei movimenti delle mani e dita può essere vantaggiosamente eseguita per mezzo di un guanto sensoriale. Tipicamente, il guanto sensoriale è costituito da un guanto leggero ed elastico con sensori flessibili incorporati, che consente di fornire segnali elettrici analogici a seconda dei movimenti delle mani e dita. In generale, le capacità del movimento manuale possono essere modellate da 27 gradi di libertà (DOFs), in modo da tenere conto sia della flessione che dell’estensione delle articolazioni delle dita sia della rotazione e della flessione del polso. Human hands are essential for interacting with the surrounding environment and for communicating. Therefore, the possibility of measuring the movements of the hands and fingers, can be useful for a series of applications, such as the recognition of sign language, motor rehabilitation, for the evaluation of the surgical gesture, etc. The measurement of the movements of the hands and fingers can be advantageously performed by means of a sensory glove. Typically, the sensory glove consists of a light and elastic glove with built-in flexible sensors, which allows to provide analog electrical signals depending on the movements of the hands and fingers. In general, the capabilities of manual movement can be modeled from 27 degrees of freedom (DOFs), in order to take into account both the flexion and extension of the finger joints and the rotation and flexion of the wrist.
La presente invenzione riguarda un guanto sensoriale in grado di percepire i movimenti delle dita che implementa un apparato ed un metodo finalizzato a potenziare la durata della carica della batteria del guanto stesso. In particolare, l’apparato proposto è basato su sensori resistivi e trasduttori a radiofrequenza, piezoelettrici e termoelettrici. Il guanto è dotato di sensori flessibili, un microcontrollore e un trasmettitore. The present invention relates to a sensorial glove capable of perceiving the movements of the fingers which implements an apparatus and a method aimed at increasing the duration of the battery charge of the glove itself. In particular, the proposed apparatus is based on resistive sensors and radio frequency, piezoelectric and thermoelectric transducers. The glove is equipped with flexible sensors, a microcontroller and a transmitter.
Al giorno d'oggi il recupero di energia da fonti ambientali (harvesting=raccolta) è un modo innovativo per catturare e immagazzinare energia per dispositivi detti autonomi, come quelli utilizzati nell'elettronica indossabile e nei sistemi di reti di sensori, anche wireless. In questo contesto, l’energia libera disponibile, soprattutto a radiofrequenza, aumenta di giorno in giorno grazie all'enorme numero di canali TV trasmessi, accessi hotspot Wi-Fi, infrastrutture di telefonia mobile, ecc. Tuttavia, tutti questi segnali hanno valori di potenza assolutamente non costanti, che dipendono dalla scelta dei luoghi o dall’ambiente che li circonda quindi è bene dotare i cosiddetti sistemi autonomi o ad autonomia prolungata di altre fonti di energia recuperate ad esempio dalle differenze termiche tra il dispositivo e l’ambiente o dalle vibrazioni. Nowadays, the recovery of energy from environmental sources (harvesting = collection) is an innovative way to capture and store energy for so-called autonomous devices, such as those used in wearable electronics and in sensor network systems, including wireless ones. In this context, the free energy available, especially radio frequency, is increasing day by day thanks to the huge number of TV channels broadcast, Wi-Fi hotspot accesses, mobile phone infrastructures, etc. However, all these signals have absolutely not constant power values, which depend on the choice of places or the environment that surrounds them, so it is good to equip the so-called autonomous or extended autonomy systems with other sources of energy recovered for example from the thermal differences between the device and the environment or vibrations.
In questo contesto le batterie rappresentano la fonte di alimentazione principale per i sistemi elettronici portatili a bassa potenza presenti nel mercato. Sfortunatamente, il punto debole della batteria rimane la sua durata della carica. Questo problema rappresenta anche un limite per un'ulteriore espansione di un mercato, altamente potenziale, a causa delle loro esigenze di sostituzione e ingombro. In this context, batteries represent the main power source for low-power portable electronic systems on the market. Unfortunately, the battery's weak point remains its battery life. This problem also represents a limitation for further expansion of a highly potential market due to their replacement and bulk requirements.
Attualmente, sistemi dotati di Harvesting energetico per i sistemi indossabili stanno acquisendo sempre più interesse. Nello specifico, la fonte di energia richiesta da un guanto sensoriale può essere raccolta per mezzo di diverse fonti di energia, a seconda dell'applicazione e dell'ambiente, come ad esempio elettromagnetica, solare, termica, acustica, ecc. L'approccio attuale si basa su batterie di grandi dimensioni o sistemi cablati, che sono poco pratici e poco confortevoli. Currently, systems equipped with Energy Harvesting for wearable systems are gaining more and more interest. Specifically, the energy source required by a sensory glove can be collected by means of different energy sources, depending on the application and the environment, such as electromagnetic, solar, thermal, acoustic, etc. The current approach relies on large batteries or wired systems, which are impractical and uncomfortable.
L’apparato ed il metodo oggetto del presente trovato permettono di estendere la durata della batteria di un guanto sensoriale integrando tre diverse soluzioni di energy harvesting. Le tre soluzioni possono essere disponibili simultaneamente. L’apparato oggetto dell’invenzione integra: 1) guanto sensoriale; 2) rete di sensori per rilevazione movimenti, 3) array di generatori termoelettrici (TEG) applicati sull'avambraccio e sul braccio umano, 4) dischi piezoelettrici impilati in numero dipendente dallo spazio disponibile (PZT), posizionati nel tacco di una scarpa, in modo da raccogliere energia dalla pressione generata dai piedi durante una camminata o una sessione di corsa, 5) circuiti a doppia banda RF per catturare energia dalla potenza RF circostante. The apparatus and the method object of the present invention allow to extend the battery life of a sensorial glove by integrating three different energy harvesting solutions. The three solutions can be available simultaneously. The apparatus object of the invention integrates: 1) sensory glove; 2) network of sensors for motion detection, 3) arrays of thermoelectric generators (TEG) applied on the forearm and on the human arm, 4) piezoelectric discs stacked in number depending on the available space (PZT), positioned in the heel of a shoe, in to collect energy from the pressure generated by the feet during a walking or running session, 5) dual RF band circuits to capture energy from the surrounding RF power.
Con riferimento alla figura 1 l’apparato si compone di: With reference to Figure 1, the apparatus consists of:
- unguantosensoriale (101) indossatodalla mano realizzato mediante materiale di qualunque genere che si estende fino al braccio per ospitare tutta la parte di sensori (102) e di trasduttori (103); - a sensorial glove (101) worn by the hand made of any kind of material which extends up to the arm to house all the part of sensors (102) and transducers (103);
- un alloggio posto nella scarpa (104) sia del piede destro che del piede sinistro per ospitare trasduttori piezoelettrici; - a housing placed in the shoe (104) of both the right foot and the left foot to house piezoelectric transducers;
- i sistemi di collegamento tra i vari blocchi ed una batteria posta sull'avambraccio o in alternativa sul braccio sempre sostenuta dal materiale di cui è compostoil guantosensoriale; - sistemi di collegamento filare tra i vari oggetti tra cui un sistema di trasmissione dati a radiofrequenza posto nelle vicinanze della batteria. - the connection systems between the various blocks and a battery placed on the forearm or alternatively on the arm always supported by the material of which the sensor glove is made; - wire connection systems between the various objects including a radio frequency data transmission system located near the battery.
Per quanto riguarda i sensori (102) del guanto sensoriale questi possono essere tipo resistivo capacitivo o anche inerziale. Tutti i trasduttori del sistema di Energy harvesting possono avere forme e dimensioni differenti tra di loro e differenti in generale; la parte di trasduzione Termoelettrica (TEG) è posizionata sul braccio e sull'avambraccio tramite l'utilizzo di Celle o quadrate o rettangolari o di qualunque altra forma anche flessibile. As far as the sensors (102) of the sensory glove are concerned, these can be resistive capacitive or even inertial type. All the transducers of the Energy harvesting system can have shapes and sizes that are different from each other and different in general; the thermoelectric transduction part (TEG) is positioned on the arm and on the forearm through the use of cells or square or rectangular or any other shape, even flexible.
In una sua possibile realizzazione il guanto sensoriale può essere realizzato come in figura 2, realizzato con tessuto costituito di materiale elastico anche misto, come Lycra® e combinazioni di Lycra® (105) con altri materiali, in modo da allungarsi col piegamento delle dita. Il tessuto ospita dei sensori, inglobati direttamente in esso oppure alloggiati in tasche cucite sul dorso del guanto stesso. In una possibile realizzazione il sistema di harvesting può essere realizzato come in figura 3 dove i tre blocchi di trasduzione RF (106), TEG (107) e piezoelettrico (108) sono collegati attraverso dei sistemi rettificatori (109) che evitano che uno dei tre trasduttori carichi l'altro ed alimentano il blocco di power managment (110). Questo ovviamente comporta una perdita di efficienza ma garantisce il funzionamento operativo del circuito. In one of its possible embodiments, the sensory glove can be made as in figure 2, made with a fabric made of elastic material, even mixed, such as Lycra® and combinations of Lycra® (105) with other materials, so as to stretch with the bending of the fingers. The fabric houses sensors, incorporated directly into it or housed in pockets sewn on the back of the glove itself. In a possible embodiment, the harvesting system can be realized as in figure 3 where the three transduction blocks RF (106), TEG (107) and piezoelectric (108) are connected through rectifier systems (109) which prevent one of the three transducers load each other and feed the power management block (110). This obviously involves a loss of efficiency but guarantees the operational functioning of the circuit.
L'architettura è stata testata come integrazione di schede di elementi discreti, composte principalmente da un microcontrollore esterno e da una scheda di trasmissione RF commerciale. I risultati delle misurazioni hanno dimostrato una durata prolungata della carica della batteria a parità di condizioni di utilizzo, considerando diversi scenari operativi. The architecture was tested as an integration of discrete element boards, consisting mainly of an external microcontroller and a commercial RF transmission board. The results of the measurements showed a prolonged duration of the battery charge under the same conditions of use, considering different operating scenarios.
Ad oggi non sono presenti in letteratura o in altri depositi brevettuali sistemi o apparati aventi tali sistemi sensoriali posti nelle posizioni e con le modalità descritte. To date, there are no systems or apparatuses in the literature or in other patent deposits having such sensory systems placed in the positions and in the manner described.
