large scale triboelectric nanogenerator and self-powered pressure sensor array using low cost roll-to-roll uv embossing
Thanks to the ease of manufacture, high efficiency, and wider selection of materials, it has become a more efficient mechanical energy collection solution than conventional mechanisms such as piezoelectric and induction motors.
Traditional manufacturing techniques for achieving TENGs include plasma etching, soft etching, and nano-particle deposition for higher performance.
However, the lack of truly scalable manufacturing processes remains a key challenge and bottleneck in bringing Tencent to the path of commercial production.
In this paper, we show the manufacture of large-scale friction electric nano-generators (LS-TENG)using roll-to-

Roller UV stamping is made of thin photosensitive polyurethane sheets by designing micro-patterns, photographing and developing photosensitive polyurethane sheets in chemical solutions.
The flower press roller is 50 cm long in the axial direction and 16 cm in diameter.
Then, attach 1mm thick pattern polyurethane sheet to the flower press roller using double-
Double sided tape.
In order to obtain the joint roller mold as narrow as possible, the circumference length of the polyurethane flexible mold needs to be cut precisely, taking into account the double

Coated with UV curing resin.
UV curing resin is a solventfree acrylate-

Thereafter, the film is emblazoned using the impression roller manufactured in the previous step.
The UV lamp uses the UV lamp to shine directly under the flower press roller.
It is used to solidify the UV curing resin after the resin flows and fully fill the cavity on the mold.
After the coating, stamping and separation process is completed, the micro-pattern on the mold is transferred to the PET film.
Therefore, the patterned PET film with micro-pattern is obtained by Rollingto-

The sensor uses a 5 v DC bias (DC)power supply (see ).
Then, when the sensor pixel is stimulated by external force, the output of the pixel and force sensor is measured in real time.
