2 is a diagram illustrating an example of a configuration of an electronic device capable of converting physical properties according to an embodiment of the present invention. The electronic device capable of converting physical properties according to the embodiment of FIG. 2 may include an electronic device unit 210 having flexibility and elasticity and a platform 220 capable of converting physical properties. The electronic device unit 210 having flexibility and elasticity may include a stretchable display 211, a stretchable sensor 212, and a first silicon polymer 213, and the platform 220 capable of converting physical properties is a gallium frame. 221 and the second silicone polymer 222 may be included. The gallium frame 221 may be disposed between the first silicon polymer 213 and the second silicon polymer 222, and the platform 220 capable of converting physical properties according to the change in physical properties according to the temperature of the gallium frame 221 Can lead to changes in the physical properties of

In the embodiments of the present invention, a phase change material may be used to have a property of varying physical properties (eg, stiffness), and physical properties such as shape memory polymer (SMP) or low melting point alloy (LMPA) may be changed. Although various materials exist, the embodiment of FIG. 2 shows an example in which gallium is used as an example of a phase change material. Gallium has a sufficiently large stiffness of 9.8 GPa when it is solid, but it can be liquefied at skin temperature. For example, a gallium frame inside the polymer (for example, between the silicone polymers 213 and 222 of FIG. 2) of a platform capable of tuning mechanical properties (for example, the platform 220 capable of converting physical properties of FIG. 2) (For example, by embedding the gallium frame 221 of FIG. 2), a phase change material may be embedded in an electronic device having flexibility and elasticity. In this case, a change between the hard form and the soft form of the electronic device may be possible according to the phase change of the phase change material. Depending on the embodiment, a gallium composite material containing gallium may be used as a phase change material. Further, as described later with reference to FIG. 21, the gallium frame 221 may be implemented in a form in which gallium is mixed with a silicon polymer in the form of microdrops.

Meanwhile, according to an embodiment, the electronic device may further include a stretchable power supply (not shown) for supplying power to the stretchable display 211 and/or the stretchable sensor 212. Power may be supplied from the outside of the electronic device according to embodiments, and for this purpose, the electronic device may include a power supply unit (not shown) such as a pin connector for receiving power.

3 is a graph showing an example of a change in physical properties according to a temperature of gallium in an embodiment of the present invention. In the graph of FIG. 3, it can be seen that the physical properties of gallium vary greatly based on the melting point at all of the various thicknesses of gallium (50 μm, 320 μm, 640 μm, and 1500 μm).

4 is a stress-strain graph of gallium in a solid state in an embodiment of the present invention, and FIG. 5 is a stress-strain graph of gallium in a liquid state in an embodiment of the present invention. The stress-strain graphs of FIGS. 4 and 5 show that gallium has two distinct physical properties when it is in a solid state and in a liquid state at various thicknesses (50 μm, 320 μm, 640 μm, and 1500 μm). It shows that it is possible to implement an electronic device capable of changing physical properties by utilizing.

The melting point of this gallium is 29.8 degrees Celsius, it can melt by body temperature (36.5℃) and become a liquid, and when removed from the body, it can harden at room temperature (for example, 25℃) and become solid. In addition, gallium can be applied to various fields requiring both forms (hard form and soft form) because the speed at which the phase change occurs between solid and liquid is high.

6 to 9 are graphs showing a phase change time according to a thickness of a gallium and a thickness of a polymer in an embodiment of the present invention. The time required for the phase change of the phase change material is a very important characteristic in achieving a change in the physical properties of the electronic device to which the phase change material is applied. In the graphs of FIGS. 6 to 9, as both the thickness of the gallium and the thickness of the polymer decrease, the time required for the phase change becomes shorter, and more efficient phase change is achieved by using an external heat device as well as body temperature (36.5° C.). It suggests that it will be possible.

11 and 12 illustrate an example in which an electronic device capable of converting physical properties according to an embodiment of the present invention is used as a touch sensor. FIG. 11 shows that when an electronic device capable of converting physical properties is in a rigid form, a program can be manipulated through a wireless interface by using an elastic sensor included in the electronic device capable of converting physical properties as a touch sensor. An example of the output value according to the touch of the touch sensor is shown.

13 and 14 illustrate an example in which an electronic device capable of converting physical properties according to an embodiment of the present invention is used as a wearable device. In addition, 13 shows that the gallium frame included in an electronic device capable of converting physical properties is melted, converted into a soft shape, and attached to the curved skin, and then used as a wearable electronic device and an EMG sensor capable of measuring bio-signals. The graph of FIG. 14 shows an example of an output value according to such an EMG sensor.

15 and 16 are diagrams showing another example of a configuration of an electronic device capable of converting physical properties according to an embodiment of the present invention. Figure 15 is a gallium frame 1510 to form a platform capable of converting physical properties, a heater 1520 for helping the phase change of the platform thereon, a flexible and stretchable electronic circuit (flexible printed circuit board (PCB, 1530)), indicating that an electronic device capable of converting physical properties can be implemented. In this case, the electronic device capable of converting physical properties may be implemented such that the gallium frame 1510, the heater 1520, and the stretchable printed circuit board 1530 are embedded in the silicon polymer. 16 is a microcontroller 1610, an LED 1620, a temperature sensor 1630, a touch sensor 1640, an OLED screen 1650, and a UV sensor 1660 are implemented on a stretchable printed circuit board (PCB, 1530). It shows an example.

Each shows the state of ④ worn. At this time, FIG. 20 shows changes in temperature and ultraviolet rays (UV) measured by an electronic device capable of converting physical properties from the state of ① to the state of ④ and then to the state of ① over time. This is the graph shown.

21 is a diagram showing another example of a platform capable of converting physical properties according to an embodiment of the present invention, and FIGS. 22 and 23 are implemented using a platform capable of converting physical properties in an embodiment of the present invention. These are graphs showing characteristics measured through the pressure sensor. FIG. 21 shows a sensor for measuring pressure through a change in capacitance by making a platform 2110 in the form of a mixture of silicon polymer and gallium in the form of microdrops and attaching electrodes 2120 above and below the platform 2110. The produced example is shown. In addition, the graphs of FIGS. 22 and 23 indicate that the sensitivity of the pressure measurement and the operating range can be tuned through the change in physical properties of the pressure sensor.

Although general pressure sensors achieve very high sensitivity, they have a disadvantage in that their operating range is limited. However, a platform capable of converting physical properties (for example, the platform 2110 of FIG. 21) has a lower modulus of stiffness than a silicone polymer when it is in a soft form, and has a higher modulus of stiffness than a silicone polymer when it is in a rigid form. Therefore, a pressure sensor manufactured through a platform capable of converting physical properties has a high sensitivity when it is in a soft shape, but has a narrow operating range, but when it is in a rigid shape, it is possible to measure a high pressure, which can compensate for the narrow operating range. .

24 and 25 are diagrams illustrating an example of using a pressure sensor when the platform is in a rigid form according to an embodiment of the present invention. FIG. 24 shows that footsteps of high pressure can be measured through a pressure sensor when the platform is in a rigid form, and the graph of FIG. 25 shows an example of the output value of the pressure sensor measured through the footsteps.

26 and 27 are diagrams showing an example of using a pressure sensor when the platform is in a soft shape according to an embodiment of the present invention. FIG. 26 shows that pulse measurements in the vicinity of the neck can be measured through a pressure sensor when the platform is in a soft shape, and the graph of FIG. 27 shows an example of output values from the pressure sensor measuring the pulse rate.

Broadly applying this method, it is also possible to fabricate sensors that measure mechanical properties, such as strain, bending, and/or distortion, in addition to pressure.

In addition, a physical sensor that measures changes in various physical quantities such as temperature, force, vibration, sound, acceleration, and/or magnetic field, in addition to pressure, can be manufactured using a platform capable of converting physical properties through the description of the pressure sensor. In this case, it will be easy to understand that the sensitivity or motion range of the physical quantity measurement can be adjusted according to the conversion of the physical properties of the platform.

Steps 2810 and 2820 included in the method for converting physical properties according to the present exemplary embodiment may be performed by an electronic device including a platform in which physical properties are converted according to temperature, a temperature controller for controlling the temperature, and a controller.

In step 2810, the electronic device may control physical properties of the platform by adjusting the temperature through the temperature controller according to the control of the controller. As an example, the controller may be included in the electronic device in the form of the microcontroller 1610 described with reference to FIG. 16, but any processor capable of controlling the temperature by controlling the temperature controller may be used without limitation. The temperature control unit was previously described through the heater 1520 of FIG. 15, and may be designed to have elasticity, and may be designed to include various components capable of controlling temperature such as a thermoelectric element as well as the heater 1520. have. At this time, at least one of the shape, rigidity, and elasticity of the electronic device may be converted according to the converted physical properties of the platform. As a more specific example, the conversion of physical properties may include a phase change between a solid state and a liquid state according to the temperature of the phase change material included in the platform. In this case, in step 2810, the electronic device adjusts the temperature above the threshold value through the temperature control unit to phase change the phase change material included in the platform from a solid state to a liquid state, or adjust the temperature to below the threshold value. The phase change material included in the platform may be phase changed from a liquid state to a solid state.

Meanwhile, the electronic device may further include an elastic sensor coupled to the platform. In this case, step 2820 may be further performed as follows.

In step 2820, the electronic device may process the output value of the stretchable sensor in a state in which at least one of shape, stiffness, and stretchability is converted. For example, the stretchable sensor may include a stretchable printed circuit board coupled to the sensor unit and the output unit. In this case, the electronic device may control the output unit through the control unit based on the output value of the sensor unit coupled to the stretchable printed circuit board in a state in which at least one of shape, stiffness, and stretchability is converted in step 2820. Depending on the embodiment, the control unit may also be implemented in a form coupled to a printed circuit board.
