DETAILED DESCRIPTION

[0014] Electronic stickers may be manufactured on flexible substrates as layers and packaged together. The package may then have an adhesive applied to one side to provide capability for sticking the electronic devices to surfaces. The stickers can be wrappable, placed on surfaces, glued on walls or mirrors or wood or stone, and have electronics which may or may not be ultrathin. Packaging for the electronic sticker can use polymer on cellulose manufacturing and/or three dimensional (3-D) printing. In one example, the electronic stickers are used to provide lighting capability as shown in FIGS. 1-3. FIG. 1 is a top view of an electronic sticker 100 with light emitting diodes (LEDs) according to one embodiment of the disclosure. FIG. 2 is side view of the electronic sticker 100 with LEDs of FIG. 1. FIG. 3 is a partially exploded perspective view of the electronic sticker 100 with LEDs of FIG. 1. An electronic sticker 100 may include layers 110, 120, and 130. Although three layers are shown in FIG. 1, an electronic sticker may include more or less layers.

[0015] The first layer 110 may include a wireless module 112, such as an integrated circuit (IC) including a controller or processor and associated radio circuitry for performing wireless communications. The wireless module 112 may provide support for wireless communications according to IEEE 802.11 WiFi, Bluetooth, Long Term Evolution (LTE), and/or other wireless communication standards.

[0016] The second layer 120 may include a power coil 122 for receiving energy to power electronic components on the layers 110, 120, and/or 130. For example, the power coil 122 may be inductively coupled to a permanent or mobile power source to energize the system 100. In one example, the system 100 may be applied as a sticker to a receiving element that is affixed to an infrastructure power system, such as the electrical system in a home. In another example, the system 100 may be applied as a sticker at a location and a mobile power unit or a mobile phone brought into proximity with the system 100 to temporarily power the system 100. In one embodiment, a flexible battery (not shown) may be integrated with the system 100 or an external battery (not shown) may be attached to the system 100. The battery may be coupled to the power coil 122 to receive energy to be stored. The system 100 can then be operated in the absence of a power source for short or long durations of time based on a capacity of the battery. Although a battery is described, other configurations may be integrated with and attached to the system 100 for energy storage. For example, metal-insulator-metal (MIM) capacitors (not shown) may be manufactured in a layer of the system 100 and used to store energy received from the coil 122.

[0017] The third layer 130 may include light emitting diodes (LEDs) 132 that convert energy to visible light to illuminate areas. The LEDs 132 may be coupled to other layers, such as to the power coil 122 on the second layer 120 and to the wireless module 112 on the first layer 110. The LEDs 132 may receive energy from the power coil 122 under control of the wireless module 112. For example, a switch (not shown) may couple the LEDs 132 to the power coil 122, and the switch may be toggled on and off by the wireless module 112 to turn on and off the LEDs 132. As another example, dimmer circuitry (not shown) may be coupled between the LEDs 132 and the power coil 122 and controlled by the wireless module 112 to control an intensity of the light output of the LEDs 132.

[0018] The wireless module 112 may be controlled from a local device, such as a user's mobile phone located in the room with the LEDs 132. In one scenario, a user may tap their mobile phone to the electronic sticker, upon which the power coil 122 is energized by the battery in the mobile phone to activate the wireless module 112. The user's mobile phone then pairs with the wireless module 112, upon which a control application activates on the user's mobile phone. The control application may include a power button for turning on and off the LEDs 132, a dimmer slider for controlling an intensity of the LEDs 132, and/or a color selector for selecting a color of light emitted by the LEDs 132. The wireless module 112 may also or alternatively be controlled from a remote device, such as a user's laptop while the user is away from their home.

[0019] Although a light emitting electronic sticker is described above, other functionality may be provided in the various layers of the system 100. In another embodiment, an electronic sticker may be configured as a smoke detector. Smoke sensors may be integrated in a third layer 130 that is outward facing towards the environment around the sticker. The smoke sensors may be coupled to a wireless module that can communicate information from the smoke sensors, such as the presence of smoke in the area. Further, although smoke sensors are described, any sensor may be integrated in the electronic sticker. For example, a carbon monoxide detector may be included with or in the alternate to the smoke sensor. As another example, a water sensor may be integrated with an electronic sticker and used to detect leaky pipes or overflowing tubs and sinks. In yet another example, a temperature sensor or ultraviolet (UV) light sensor may be integrated in an electronic sticker. The sticker may be placed in rooms throughout a house, on windows throughout the house, and/or on a patio or in the yard. A user may activate the sensors with their mobile phone to obtain measurements from the sensors integrated in the stickers. For example, a user may tap their phone against the electronic sticker to energize the power coil and pair with the wireless module, which then transmits to the user's phone a measurement from the integrated sensor, such as the local temperature. The user's mobile device may then store the measurement for later viewing or automatically launch an application that provides the information to the user. In another example, a rain gauge sensor may be integrated in an electronic sticker. The rain gauge may be used to determine recent rainfall amounts and the wireless module activated to send commands to a sprinkler system.

[0020] In yet another embodiment, the electronic stickers may provide services to other devices. For example, an electronic sticker may provide recharging capability to mobile devices. Such an electronic sticker may include the power coil 122 shown in FIG. 1, but use the power coil 122 to transmit energy to other devices. The electronic sticker may be hard-wired to an electrical system, such as a house's 120V AC electrical system. One layer of the electronic sticker may include appropriate circuitry to generate an appropriate level signal for the power coil 122. When a user's mobile device is placed against the sticker, the user's mobile device may receive energy to recharge its battery. Although similar charging pads are conventionally available, they all involve rigid structures that are not suitable in all areas and that are bulky and unsightly. When manufactured as an electronic sticker, such a charging device may be ultrathin, conform to surface shapes, and adhere to the surface in a much smaller package than conventional wireless charging pads.

[0021] FIG. 4 is a flowchart of a method 400 of making an electronic sticker according to one embodiment of the disclosure. In operation 402, a flexible substrate comprising a base for one or more electronic devices may be provided. For example, first layer 110 may form the flexible substrate for the one or more electronic devices. In operation 404, one or more layers may be provided on the flexible substrate. The one or more layers may form components for the one or more electronic devices. A top layer of the one or more layers may be exposed to an environment around the top layer and include components to interact with the environment. For example, third layer 130 may form the top layer of the one or more layers.

[0022] At least one layer of the one or more layers may include an inductive power coil configured to receive power for operating the one or more electronic devices. For example, second layer 120 may include power coil 122 for receiving energy to power electronic components on the layers 110, 120, and/or 130. At least one layer of the one or more layers may include one or more light emitting diodes (LEDs). The LEDs may be configured to receive power from the inductive power coil. For example, the third layer 130 may include LEDs 132 that may receive energy from the power coil 122. At least one layer of the one or more layers may include a wireless module. The wireless module may be coupled to the inductive power coil and to the LEDs. For example, the LEDs may receive energy from the power coil 122 under control of the wireless module 112. The wireless module may be configured to receive commands to operate the LEDs and to operate the light emitting diodes LEDs based, at least in part, on the received commands.

[0023] The method 400 may further include providing an adhesive backing on the flexible substrate to form a sticker. The method 400 may further include coupling a flexible battery to the one or more layers. The method 400 may further include packaging the flexible substrate using polymer on cellulose manufacturing using 3D printing.

[0024] At least one layer of the one or more layers may include one or more sensors. The one or more sensors may be configured to receive power from the inductive power coil. At least one layer of the one or more layers may include a wireless module coupled to the inductive power coil and to the one or more sensors. The wireless module may be configured to receive data from the one or more sensors and to wirelessly communicate the received data to a client device. The one or more sensors may include at least one of a smoke detector and a carbon monoxide detector. For example, third layer 130 may include a smoke sensor integrated therein. The one or more sensors may include a rain gauge.
