Is Sequential Deposition the Key to Flexible and Wearable Electronics?

In summary, University of Pennsylvania engineers have developed a new method for creating electronic devices by depositing their components in the form of liquid nanocrystal "inks." This process allows for the integration of electrical components into flexible or wearable applications, making it compatible with a wide range of materials and suitable for larger areas. This technology suggests a new approach to scaling, focusing on ergonomic scaling rather than area scaling, and has potential for incorporating smaller transistors into everyday items such as socks and shirts.

Just wondering if this will be the next step in electronics, ie, wearable devices and printing electronics.

Now, University of Pennsylvania engineers have shown a new approach for making these devices: sequentially depositing their components in the form of liquid nanocrystal "inks."

Their new study, published in Science, opens the door for electrical components to be built into flexible or wearable applications, as the lower-temperature process is compatible with a wide array of materials and can be applied to larger areas.

Very interesting technology, and suggestive of a different scaling axis - ergonomic scaling as opposed to area scaling. I imagine there are a lot of functions that require 100's or 1000's of transistors (as opposed to orders of magnitude more transistors) that would be very handy to have woven into ones socks or shirt. There is nothing in the article to suggest these transistors can't scale to be small, I am thinking that large area transistors would more easily stand up to being in a dryer with wool socks, though.
 

1. What is a transistor and why is it important?

A transistor is a semiconductor device that is used to amplify or switch electronic signals. It is an essential component in many electronic devices such as computers, smartphones, and televisions.

2. What is the new way to make transistors?

The new way to make transistors is by using a 2D material called graphene, which is a single layer of carbon atoms arranged in a hexagonal lattice. This method is known as the "graphene field-effect transistor" and it has the potential to revolutionize the semiconductor industry due to its superior performance and efficiency.

3. How is the new method different from traditional transistor manufacturing?

The traditional method of making transistors involves using silicon, a 3D material, and a complex and expensive process called lithography. The new method using graphene is simpler, cheaper, and more scalable, making it a more attractive option for mass production.

4. What are the benefits of using graphene in transistors?

Graphene has several advantages over traditional materials used in transistors. It is thinner, lighter, and more flexible, making it ideal for use in flexible devices. It also has higher electron mobility, meaning it can carry electric current faster and more efficiently, resulting in faster and more energy-efficient devices.

5. When can we expect to see this new technology in consumer products?

While the research and development of graphene transistors are still ongoing, some companies have already started incorporating this technology into their products. It is expected that within the next 5-10 years, we will see a significant increase in the use of graphene transistors in various electronic devices.
