Recent advances in inkjet-printing technologies for flexible/wearable electronics

“…8–11 The advent and improvement of printed electronics have facilitated the manufacture of flexible/stretchable electronics. 12 It is reported that the market for printed electronics has reached ≈7.8 billion US dollars in 2020, and it is expected to rise to ≈20.7 billion US dollars by 2026. 13,14 Printed electronics have attracted great interest in commercialization because of the ability to manufacture large-scale, low-cost electronic devices on a variety of substrates.…”

Fabricating Flexible Strain Sensor with Direct Writing Graphene/Carbon Nanotube Aerogel

“…For traditional manufacturing technology, the cost of a single product gradually decreases with the increase in production quantity. Printing additive manufacturing technology overturns this cost model, making the cost of a single product and the output show an independent relationship, which is a factor to be considered when achieving scalability . In addition, even with their high complexity, additive manufacturing devices usually do not require new molds, making them less costly to manufacture than other technologies such as lithography and electrochemical deposition .…”
