Self-Healing Electronics: A Superpower from Sci-Fi Transformed to Everyday Devices

CADDZOOM

Inspired by the Wolverine an X-Men character, a group of researchers created transparent, self-repairing and a highly stretchable material with electronical activation capabilities. This material is suitable especially to improve the performance of electronic devices such as smartphones and robots. Such material is created by combining a stretchable polar polymer with an ionic salt. Some of its features are:

  • This material has stretching capability to expand itself up to 50 times its size.
  • It can automatically repair itself within 24 hours of damage.
  • One of its applications can improve the battery lifetimes of the electronic devices.

One of the professors from the team believes that the market will have a range of self-healing products within the next three years such as the smartphone screens. Self- repairing robots is the most exciting application the scientists are working on. Although this material will change the lifestyle of people, scientists are still exploring it’s applications.

Four Key Advanced Manufacturing Technologies Used in Aerospace

CADDZOOM

Advanced Manufacturing technologies have become one of the most important parts of the Aerospace industry. This is because of the unique challenges that the aircraft designers deal with. The aircraft designs need to consider the environmental conditions using strong materials that are both lightweight and temperature resistant. Such designs require micro and Nano- machining techniques. Here are four advanced machining technologies that are used in the Aerospace industry.

Additive Manufacturing  

The Aerospace industry was quick to identify the benefits and potential of Additive Manufacturing to design its planes. The technology uses Power-Bed laser printing systems to build its most components. Additive manufacturing technology is used to build structures that work within the fuselage with features such as reduced weight and reduce heat. An additive manufacturing technique, commonly known as the Fused Deposition Modeling, is used to create semi-hollow parts of the aircraft wings by both adding strength and reducing weight.

Composite Materials

Composite materials are widely used to design aircraft. Aerospace engineers prefer using these materials because of their favorable characteristics of flexibility, strength, temperature and chemical resistance. Composite materials and advanced polymers in the design help to improve performance and reduce lifecycle costs. These materials also reduce the overall weight of the aircraft cutting short their fuel consumption and carbon emissions.

Robotics

Robots are used in the aerospace industry to manage the labor-intensive process, particularly when lifting and handling tasks are to be done. The industry is using powerful robots in its manufacturing plants to move and join aircraft parts. Robotics is also taking care of manufacturing process that is hazardous to people such as painting and welding.

Laser Beam Welding

This technology offers rapid and high precision work as compared to the traditional welding techniques. Laser welding is, therefore, a preferred solution for handling materials when repeatability and high accuracy is required. The most advantageous property of this technique is that it transfers very little heat to the material that is welded. This way it does not create a heat affected zone around the weld, ultimately not compromising the strength and performance of the material.

With the widespread use of these technologies, the aerospace industry has also inspired several other industries to use these technologies in the manufacturing process. These techniques have undoubtedly simplified the manufacturing processes and reduced costs to a greater extent. Their accuracy and precision have reduced the number of failure points in the manufacturing process.

PERSONAL BRANDING SKILLS- THEY DON’T TEACH IN ENGINEERING SCHOOL

CADD CENTRE

To be successful in your career, you need branding skills. These skills help an individual to attain their goals easily. Although personal branding revolves around the customer preferences, it lays its primary focus on improving an individual personality. Here are some skills that promote personal branding for individuals and teams to progress professionally.

The Interpersonal Skills- It is all about socializing with people and expanding the follower base. Failure in communication skills can make professional miss opportunities.

The Non-verbal Communication Skills- These skills help a professional to go beyond the boundaries of the words to have a clear meaning of what the other person wants to say.

The Dressing Style- Sometimes the dressing style of people can reveal their current state of mind and how they want other people to see them.

Although these skills are not taught in the formal education system, these skills help professionals reach heights in their career.

Meet the Indian Teen and his Invention, Kalamsat – Smallest Satellite for NASA

CADD CENTRE

India again broke a global space record by launching world’s lightest satellite weighing 64 grams, called Kalamsat, developed by 18-year-old Tamil Nadu student Rifath Sharook and his team.

Named after former Indian President, Dr. APJ Abdul Kalam Azad, Kalamsat was the only Indian payload in the mission. A NASA sounding rocket flew the tiny satellite, and the lift-off was from the space agency’s Wallop Island around 3 PM (IST).

In conversation with Mission Director, Srimathy Kesan, she said that the total flight time of Rocket was 240 minutes and Kalamsat got separated from the rocket in 125 minutes after lift-off. While learning about the satellite’s post-launch, we also came to know that it fell into the sea. After recovering, NASA will send it back to the team for decoding the data.

Specification of the “Tiny Satellite”

  • It can be held in one’s palm as it is 3.8cm cube.
  • The structure is 3D printed with reinforced carbon fiber polymer.
  • It is equipped with a nano Geiger-Muller for measuring radiations in the space.

The incredible achievement makes us believe that Space is not unreachable and has no boundaries, therefore, let us all do research and conquer the Mars soon.

Ransomware, Digital India and the Growing Cyber Threats

CADD CENTRE

The latest ransomware attack “WannaCry” has become a horror for most of the organization and countries. Looking at the speed at which it has spread has in fact raised questions on cybersecurity. Especially in countries like India where the nation is moving towards digitization through initiatives like “Digital India”, this attack has raised doubts on the safety of digital transactions.

With a strong motive to create a cashless economy, the shift towards digital payments has already increased significantly in India. In a survey, around 88% of the respondents showed their willingness to make use of digital payments and 48% were already using it for more than 75% of their transaction. However, all of them were concerned about the security, especially in the end devices. As more number of users is shifting towards digital payments, the chances to security risks such as online fraud and information theft are also increasing. Tax and advisory service provider point out the lack of awareness and poor digital payment ecosystem as a reason for online fraud and virus attacks.

Addressing the issues, there is a requirement of regulatory framework, foolproof security measures, convenience and immediate settlements to ensure long-term success for digital payments.
