Flexible and cross-functional gadgets are on-demand nowadays. MEMS technology meets most of the criteria of today’s customers including business representatives and end-users. The focused attention is paid to pliable micro tech units in the 21st century. They are possible to replace most traditional devices that are costlier and bulkier for manufacturers and other market players.
One of the great solutions that can improve the performance of the gadgets based on the microelectromechanical systems in general or just some of their micro components like optical modules in the MEMS laser projector units or chips, actuators, or sensors in other models is using of the alloys of nickel and cobalt.
What Are Ni-CO Alloys?
Flexible electronics are associated with flex circuits that make the devices extremely cross-functional and applicable for different purposes. Among the most common flexible electronic models are monitors, portable gadgets, MEMS sensors, radio-frequency identifiers, etc.
All these units are used for different applications and make the life of average consumers easier. Additionally, flexible electronic equipment helps market players automate most manufacturing and industrial processes.
Speaking about MEMS sensors and chips, Ni-CO alloys while used for the film fabrication can make a difference and promote even more advantages for the micro-gadgets like:
- Compact dimensions;
- Weather and heavy load resistance.
In the 21st century, most scientists switched to the investigations of metal foils that are not lacking in advantageous properties for micro tech units. For example, it is observed the high-level stability to the extreme temperatures (including temperature bouncing and bumps), improved mechanical strength, and better impact absorption impacts.
Why Are Nickel-Cobalt Films Great for Micro Gadgets?
Films made of nickel-cobalt alloys can improve these devices significantly. Ni-Co is a blend of weather-resistant properties and flexibility at once. That is why thin films made of nickel-cobalt alloys can come in handy for the micro tech unit improvements.
MEMS structural components filmed with this material are expected to obtain high-grade durability, increased electrical properties, and improved sensory background. The notable feature of metal foils that characterizes well the films made of Ni-CO alloys is their flexibility – any required form is available.
Key Findings of the Ni-Co Alloy Study
The micro matching procedure is applied to shape films made of nickel-cobalt alloys into different forms required for micro gadgets. The study included analyzing and monitoring of various parameters and specifications including:
- The chemical makeup;
- Electric characteristics;
- Thermal specifications;
- Mechanical properties.
According to the results of the undertaken survey, films made of Ni-Co alloys demonstrated high-level performance in the context of the structural substrate. The sound toughness of the metal foils was observed. The film is not lacking in tensile strength as well (even higher than the steel and other materials perform).
While comparing other properties of Ni-CO alloy films with the stainless steel-made samples, it was seen that mechanical strength and thermal diffusivity are also higher when it comes to nickel-cobalt ones.
This way the adequate reaction to heat is achieved when it comes to micro tech units of any kind. The experts detected the improved sensor properties of the Ni-CO alloy films that will be suitable for external coverage of the MEMS structural elements.
It is reasonable to take a closer look at the metal foils in the context of micro gadgets. Films made of nickel-cobalt alloys are especially matching to the requirements of the MEMS-based devices including sensors, lasers, mirrors, projectors, actuators, and chips.
Almost any of the structural elements presented in microelectromechanical systems can be covered with this material that performs better electric, mechanical, and thermal properties than even steel, silicone, or glass coating.
