What do you think they are made of?
Can you guess how these clothes were made? Using 3D printing techniques.
II. Making a prediction
Wearing the future
What materials will be used?
What kind of technology will be applied?
III. Reading for structure
Para 1: Introduction (Technology is changing our clothes)
Paras 2-4: Regulating temperature (Chinese research team used 3D printing techniques to make clothes that can regulate body temperature)
Paras 5-7: Creating energy (Korean scientists made clothes that can generate electricity)
Para 8: Sending signals (American students made clothes that can send signals to cellphones)
IV. Reading for details
Part 1 (Para 1):
Q: What will the following text be about?
A: Some of the ways in which technology is changing the clothes people wear.
Part 2 (Paras 2-4):
Q1: What techniques have the Chinese research team developed to produce the fabric?
A1: 3D printing techniques.
Q2: How can the material regulate the wearer’s temperature?
A2: A polymer is trapped inside a fabric that can alternate between a crystal and a non-crystal form. While it can absorb heat in its crystal form, it can release heat in its non-crystal form, therefore regulating the wearer’s temperature.
Q3: What is the significance of the creation of this clothing?
A3: It is the first time a scalable and controllable 3D printing strategy has been used to create such clothing.
Part 3 (Paras 5-7):
Q1: What have scientists in South Korea developed?
A1: A wearable fabric that generates electricity as it bends and stretches.
Q2: What features of the clothing are mentioned?
A2: ① It contains nanogenerators that turn friction into electricity.
② The energy can be effectively stored.
③ It feels like normal clothes.
④ Wearers only need to move naturally.
Part 4 (Para 8):
Q1: How was the clothing produced?
A1: Stitching conductive thread into cotton t-shirts.
Q2: What device can receive signals from the clothing?
A2: Cellphones.
