| Abstract Scope |
We repot a clean room free laser induced nanowires welding process for a multi targets detection sensing system. Nanowires have unique structural properties comparing with high dimensional materials such as films and bulks. Especially, single nanowire is attractive as a basic component for nanoelectronics and ultrasensitive devices. In this works, two different types of laser were used for studying the differences in effect on nanowire after laser irradiation. Based on different working properties, a 523 nm continuous wave laser and a 1030 nm femtosecond pulse laser were selected for comparison studies. Based on experimental results, laser induce nanowire welding process was developed. After welding, the contact resistance between nanowires and substrate electrodes was reduced significantly. Also, with an ultra-fast laser, a high accuracy processing of oxidizable metal was achieved under air condition. This method also applied to a multi targets detection smart sensing system through pattern recognition and machine learning.
