Nanyang Technological University (NTU Singapore) has successfully printed complex electronic circuits using a common t-shirt printer. The electronic circuits are printed using unique materials in layers on top of everyday flexible materials such as plastic, aluminium foil and even paper.
Resistors, transistors and capacitors, the key components of a complex electronic circuit, are printed using non-toxic organic materials like silver nanoparticles, carbon and plastics.
Associate Professor Joseph Chang, leader of the NTU Singapore research group said their unique printing technique has made mass production of cheap disposable electronic circuits possible.
“This means we can have smarter products, such as a carton that tells you exactly when the milk expires, a bandage that prompts you when it is time for a redressing, and smart patches that can monitor life signals like your heart rate,” said the electronics expert from NTU’s School of Electrical and Electronic Engineering. … (Read more)
