Patent Number: 
Section: claims

1. An electro-technical device, comprising:a circuit including a coil connected to a voltage source for receiving a current therefrom and connected to an output device;the circuit including a breakable junction;the circuit including a photodiode for receiving a light signal from a fiber optic cable receiving a light signal from a sensor; anda permanent magnet having a pole end opposing a common pole end of the coil, wherein when the coil receives an increased current from the photodiode, the coil creates an magnetic flux that repels against the common pole of the permanent magnet in order to cause the breakable junction to break and disrupt a connection between the voltage source and the output device. 2. The electro-technical device according to claim 1, wherein the breakable junction is disposed between the permanent magnet and the coil. 3. The electro-technical device according to claim 1, wherein the breakable junction is made by 3-D printing. 4. The electro-technical device according to claim 1, wherein the sensor includes one of a temperature sensor, a pressure sensor, or a flow sensor. 5. An electro-technical device, comprising:a plurality of circuits each including a coil connected to a voltage source for receiving a current therefrom and connected to an output device;each of the plurality of circuits including a breakable junction;each of the plurality of circuits including a photodiode for receiving a light signal from a fiber optic cable receiving a light signal from a sensor; andeach of the coils of the plurality of circuits having a pole end opposing a common pole end of one or more permanent magnets, wherein when the coils receive an increased current from the respective photodiode, the coils create a magnetic flux that repels against the common pole of the permanent magnet in order to cause the breakable junction to break and disrupt a connection between the voltage source and the output device. 6. The electro-technical device according to claim 5, wherein the breakable junction of each of the plurality of circuits are disposed between the permanent magnet and the coil. 7. The electro-technical device according to claim 5, wherein the breakable junction of each of the plurality of circuits are made by 3-D printing. 8. The electro-technical device according to claim 5, wherein the sensor of each of the plurality of circuits includes one of a temperature sensor, a pressure sensor, or a flow sensor. 9. A method of making an electro-technical device, comprising:connecting a circuit between a voltage source for receiving a current therefrom and connected to an output device;the circuit including a breakable junction that is 3-D printed;the circuit including a photodiode for receiving a light signal from a fiber optic cable receiving a light signal from a sensor; andmounting a permanent magnet having a pole end opposing a common pole end of the coil, wherein when the coil receives an increased current from the photodiode, the coil creates an magnetic flux that repels against the common pole of the permanent magnet in order to cause the breakable junction to break and disrupt a connection between the voltage source and the output device.
