Q & A

What are 4D printers and how do they differ from 3D printers?

4D printers use special smart materials that allow objects to change shape in response to stimuli such as heat or moisture. Unlike 3D printers, which create static objects, 4D printers produce items that can transform over time after the printing process is complete.

What is Samsung's Flex hybrid and how does it combine folding and rolling displays?

Samsung's Flex hybrid is a display that combines both folding and rolling capabilities. It allows a large tablet to be reduced in size and packed away by either folding or rolling, making it a versatile option for future display technology.

What is li-fi and how does it compare to Wi-Fi?

Li-fi is a technology that uses light to transmit data, offering speeds potentially 100 times faster than Wi-Fi. Unlike Wi-Fi, li-fi signals cannot penetrate walls, making it more secure but also limiting its range.

How do MIT's printed solar cells improve on traditional solar panels?

MIT's printed solar cells are thinner than a human hair and 18 times more efficient than traditional solar panels. They are lightweight and flexible, making them suitable for new applications like drones and disaster relief efforts.

What milestone in nuclear fusion was achieved in December 2022?

In December 2022, scientists in the US achieved a breakthrough in nuclear fusion, producing more energy from the reaction than was put into heating the particles. This achievement proves that nuclear fusion could provide a nearly limitless and clean source of energy.

How does the sweat-powered battery work?

The sweat-powered battery developed by scientists at Nanyang University uses human sweat to generate electricity by reacting with chloride ions in the sweat. It is small and flexible, ideal for wearable devices like smartwatches.

What are smart tattoos and how do they work?

Smart tattoos are small, flexible circuits that can be applied to the skin. They are powered by sweat and can execute commands, such as playing music when touched, offering a new form of on-body connection to the digital world.

What is the potential of microchip implants, and how are they currently used?

Microchip implants, such as RFID and NFC tags, are used to store and transmit important information. They can be used to store medical data or enable functions like unlocking doors or making payments via wrist sensors.

How does the new airport departure board technology improve the user experience?

The new airport departure board uses a 'parallel reality display' that shows personalized flight information based on the angle from which a passenger views the screen, ensuring that each person only sees the relevant details.

What is SpinLaunch, and how does it revolutionize satellite launches?

SpinLaunch is a new satellite launching system that uses a giant vacuum-sealed wheel to spin a satellite to high speeds. The satellite is then released, allowing it to reach space using significantly less fuel and at a much lower cost than traditional methods.
