Abstract

The invention discloses an inkjet printing technology based flexible wearable system and a manufacturing method thereof. A circuit is printed via an inkjet printing technology, and a fully-printed wearable system integrated with wireless energy collecting, storing and sensing units is manufactured. A flexible polymer substrate is printed and integrated with an NFC antenna, a Schottky diode, a super capacitor and a sensor. The NFC antenna and a lead are manufactured by printing via a silver nanoparticle printing ink, and the NFC antenna serves as a wireless energy reception part. A zinc oxide film is printed with the Schottky diode via a platinum nanoparticle printing ink and an aluminum nanoparticle printing ink. The super capacitor is manufactured by printing via a mixed printing ink composed of single-wall carbon nanotubes and manganese dioxide, and serves as the energy storage part. Polyvinyl alcohol / phosphoric acid solid gel serves as an electrolyte. Circuit connection is carried out according to requirements, and the flexible wearable system is further formed.

Description

technical field [0001] The invention relates to the field of inkjet printing, in particular to a flexible wearable system based on inkjet printing technology and a manufacturing method thereof. Background technique [0002] Due to the poor bending and stretching properties of circuit boards manufactured by traditional photolithography processes, it is difficult to directly manufacture complex circuit structures on flexible polymer substrates, and it has been unable to meet the manufacturing requirements of flexible wearable sensor integrated circuits. Inkjet printing technology is a high-efficiency, low-cost and high-precision liquid ink deposition technology, which can be applied to the printing and manufacturing of micro-nano component circuits. Its low temperature characteristics make it possible to manufacture electronic components on various types of substrates. Devices, and can overcome the pollution and material loss produced by traditional photolithography processes,...
