[0012] The present disclosure relates to a sensoring wood base product or article, a method for production and uses thereof.

[0013] The sensoring wood base product now disclosed will lead to a disruptive and intuitive human-machine interface, adding value and new functions to common products / substrates in the home, namely wood base wall panel's substrates and furniture, which can be seen as wood base substrates. Taking the advantage of the deposited sensors, it is now possible to include, in a more synergistic way, into the environment, the sensors directly in the wood base product, becoming part of it.

[0014] Vibrational responses are very convenient to provide an answer / feedback to the user regarding its actuation in a specific scenario. The use of sensors with this ability allows to give the user a physical response regarding its action. For example, its combination with printed capacitive touch sensors allows the user to have a physical perception of the action he has performed by the activation / inactivation of the touch sensor.

[0015] One possible embodiment is to have sensors incorporated in different pieces of furniture that can be rearranged in the living space. Those sensors will activate different actions inside the house, for example, turning the lights on / off, blinds control and an SOS help button. Alongside with them, there may be a haptic feedback system, also produced by printing technique, that will give to each one of the buttons a proper vibration feeling to the user when activated.

[0016] In an embodiment, the sensor will be applied on the back surface of the wood base substrate, while on the front it will only have a visual indication of where it should be pressed and what it will trigger, providing a seamless solution.

[0017] Control of the indoor environment is also important to users' comfort. For that, humidity and temperature deposited sensors are integrated in a wood base substrate, such as a typical furniture, like a tabletop. These sensors will monitor the conditions and send alerts or switch on / off climate control equipment whenever pre-set values are exceeded.

[0018] Moreover, this document discloses not only these embodiments, but also the incorporation of sensors that will help to detect falls or intrusions in a specific environment. For that, vibration sensors can be integrated in the wood base substrate, such as the floor of a constructive modular system and when it detects a vibration above the defined threshold, it generates an alert to the user.

[0019] This disclosure relates to a sensoring wood base product comprising a sensor for the detection of risk situation in home, which can be a humidity sensor, a sensor that detects physical orientation, a proximity sensor, an acceleration sensor, a sensor of atmospheric pressure, a sensor of molecular compounds, a sensor for detecting a chemical change, a shock sensor, a vibration sensor, a light sensor, wherein said sensor is on the surface of a wood base substrate.

[0020] The disclosed sensor is connected with an electronic control unit that can be made using a printed circuit board (PCB). The developed electronic board can be integrated and fixed on modular constructive panel cavities.

[0021] In an embodiment, the PCB part can be integrated and fixed inside the furniture, for example a tabletop or a mobile door from a furniture element.

[0022] In an embodiment, the PCB part comprises a dimension lower than 10 cm length x 10 cm width cm x 2.5 cm thickness, preferably less than 6 cm x 6 cm x 1.5 cm each side (square).

[0023] The prefabricated modular constructive technology allows the integration of sensing technology in the built environments, as well as the integration of equipmentinherent to its proper functioning, through coatings and materials associated with monitoring and sensing of spaces, namely wood base materials, facilitated by the flexibility and evolutionary capacity of the constructive system, through the optimization of the entire production process and detailed planning in the production of panels in an industrial environment.

[0024] All the panels produced in the constructive technology present a standardized form, through the machining of all its components. All wall and floor / roof panels are previously machined, having paths / negatives for the integration of vertical and horizontal infrastructures along the entire length of the panel, functionally interconnected among themselves. Through planning, it is possible in advance to create negatives directed and necessary for the integration of specific infrastructures, which require different configurations and dimensions, already in the industrial process, thus avoiding the need for additional construction / deconstruction work in the assembly of the construction system on site.

[0025] The composition of the constructive technology and its technical, structural, mechanical and functional characteristics, allow the integration of the wood base covering materials on the surface, as well as the sensing systems, monitoring and auxiliary equipment inside, through the negatives, intended for the integration of infrastructures and equipment for feeding and distributing the necessary cabling for the proper functioning of the products developed.

[0026] With the prefabricated modular constructive technology, it is possible to speed up the whole process, reflecting the integration of infrastructures in an industrial and controlled environment, thus mitigating the error and waste, enhancing the perfect integration of infrastructures ensuring in the lifetime of the buildings, if necessary, any changes, developments, maintenance or disassembly to move the complete building or part of it.

[0027] These features give the constructive system evolutionary capacity, allowing the change of constructions according to user needs. Noteworthy that this evolutionary feature in line with the process of assembly and disassembly on site, can be programmed already in the design phase and in the planning of the production of panels, allowing theexpansion or reduction of construction, as well as the continuity of infrastructures according to the future configuration.

[0028] The constructive system allows the maintenance of the sensing and monitoring systems, in space and time, through the replacement of sensors, cabling or power supply equipment, reception and communication of information according to the needs of the built space.

[0029] All the described characteristics are aligned with the principles of the circular economy and zero waste policy.

[0030] Along this description, it is considered that a wood base material or engineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives, or other methods of fixation to form composite material.

[0031] The application of this sensoring wood base product avoids the need to have additional equipment such as sensor detectors, that are often installed in a postconstruction phase, much more intrusive and not visually suiting the environment in which they are integrated.

[0032] In an embodiment, the sensor is deposited on the visible surface of the wood base substrate using deposition technology and the connection of said sensor to the control electronic unit is made through a flat cable, a printed track, an electric wire, or any other suitable connection mode or their combinations thereof, connected to the back surface of the sensoring wood base product, where it is placed in order to be imperceptible.

[0034] Furthermore, given the concerns inherent to the integration of this solution in construction systems, namely the need for maintenance of the sensors, which may require access to the power supply, electronic board and electric wiring located in the back of the products, this sensoring wood base products can comprise a specific fixing to adhere to the base constructive system. This fixing system allows the sensoring wood base products to be fixed in a non-permanent way, as achieved with conventional mortars, allowing an easy non-destructive removal in case of need of access to the control system unit of the sensor. At the same time, it allows preserving the electronic components, which do not come in contact with conventional mortars, which would also adhere to them, and therefore make impossible their removal and / or reuse after a potential failure.

[0069] The present disclosure relates to a sensoring wood base product or article, a method for production and uses thereof.

[0070] In an embodiment, for maintenance purposes, the sensoring wood base product comprises a fixing system that allows easy, non-destructive removal of said product, as an alternative to the mortars traditionally used in construction. In an embodiment, the fixing system comprises a fastener, which is enough to ensure the fixation of the component, allowing the disassembly of the piece in case of need of maintenance due to the breakdown of electric or electronic components. This technology leads to a solution that is almost-invisible, non-intrusive and easy to install and remove.

[0071] Along this description, some specific sensor will be disclosed as possible embodiments of the technology, namely printed capacitive sensor, haptic actuator, humidity sensor, temperature sensor and vibration sensor deposited over the lignocellulosic substrate to form the sensoring wood base product. Those embodiments could be part of a housing structure, namely in a modular construction system or furniture, using wood, fibreboard, high-density fibreboard, wood fibreboard, or their combinations thereof.

[0072] In an embodiment of the sensoring wood base product, the sensor is a capacitive deposited sensor, which is applied on the back surface of the wood base substrate, i.e. not in contact with the user. Said sensor is deposited directly on the wood base substrate using a conductive ink or, alternatively, deposited on polymeric layers and laminating on the wood base substrate. Both deposition processes achieve good results, either from direct deposition or lamination, but the different number of layers may have an impact since the thickness of the substrate affects the sensor response. This embodiment allows the inclusion of capacitive sensors, for example on a hollow furniture, which results on a seamless solution without the need of mechanical buttons.

[0073] In an embodiment of the sensoring wood base product, it may include a haptic feedback actuator, which is applied on the back surface of the wood base substrate, i.e. not in physical or visual contact with the user. Said actuator is deposited directly on a conductive substrate, such as polyvinylidene fluoride, and is integrated on wood basesubstrates by lamination. A different number of layers have been tested, from three to seven layers, allowing to have a vibrating feedback when a sensor is activated.

[0074] In an embodiment of the sensoring wood base product, illustrated in Figure 1, the wood base product can include a sensor that is a capacitive sensor together with a haptic feedback actuator. This embodiment can be introduced in standard furniture and can include a sensory panel on such furniture. Different alerts and / or actions can be activated by said sensory panel, and also, in an additional embodiment, a haptic feedback actuator can be coupled with said capacitive sensor in order to offer vibration feeling of the user.

[0075] In an embodiment of the sensoring wood base product, illustrated in Figure 2, the wood base product can include a humidity sensor on the surface of the wood base substrate. This sensor is deposited in the surface in contact with the environment, for a proper data acquisition of the living conditions. The deposition can be done by the direct deposition on the wood base substrate, for example by printing, or, alternatively deposited on a polymeric membrane and laminated on the wood base substrate. For the lamination of the sensor in the polymeric membrane on the wood base substrate can be used a double-sided sticker. In an embodiment, the sensor can be composed by two different layers: a conductive circuit and a sensitivity layer. In some embodiments, the sensor is encapsulated to protect the sensor, and in some specific embodiments, the encapsulation is perforated for better sensor activation and / or measurements, since it is in direct connection to the environment with said perforations. The best results were achieved with the embodiment with lamination of the wood base substrate with a double-sided sticker, after deposition on a polymeric membrane. The main advantage in this embodiment is to obtain a seamless solution to control environmental conditions, integrated in hollow furniture, less space needed for a proper data acquisition.

[0076] In an embodiment of the sensoring wood base product, illustrated in Figure 3, the sensoring wood base product can include a temperature sensor on the surface of the wood base substrate. This sensor is deposited in the surface in contact with the environment, for a proper data acquisition of the living conditions. The deposition can be done directly on the wood base substrate, for example by printing, or deposited on a polymeric substrate, such as polyimide, and laminated with a thermoplastic polymer,such as polyurethane, or pressed the polyimide substrate at the same time the structure is pressed or double sided stickered. A different number of layers were tested and the best results were achieved in the embodiment deposited in the polymeric membrane and lamination with a membrane or integrating by use of double-sided sticker. The main advantage in this embodiment is to obtain a seamless solution to control environmental conditions, integrated, for example in hollow furniture, resulting in less space needed for a proper data acquisition.

[0077] In an embodiment of the wood base product, illustrated in Figure 4, the sensoring wood base product can include a vibration sensor applied to the modular constructive system to detect abnormal activities, by vibration, for example any fall or intruders at home. In this embodiment, the sensor is deposited in both surfaces of piezoelectric commercial sheets, encapsulated with a polymeric film. Therefore, the sensor layer is integrated over the wood base substrate, being between said substrate and the modular constructive system. In order to let the sensor layer vibrate, a cavity is perforated, for example in the wood base substrate to allow the existence of space for the sensor to vibrate. To have a very defined position, the sensor layer can be fixed mechanically in two opposite extremities. The main advantage in this embodiment is to obtain a seamless integration, in modular constructive system, of a vibration sensor, hidden from the users.
