Part 01.How can dry nano printing reshape the research and development path of sensing materials?

The metal oxide semiconductor (MOS) gas sensor technology based on MEMS has significant advantages over traditional monitoring methods: ppm level sensitivity, ability to detect multiple target gases, ease of miniaturization, strong scalability, and wide range. However, in terms of sensitivity and selectivity, existing MOS technologies are still unable to meet the needs of some application scenarios. By using the VSParticle P1 nano printing deposition system, the performance indicators of the sensor can be significantly improved: on the one hand, sensitivity can be increased by maximizing the specific surface area, and on the other hand, selective optimization can be achieved by precisely controlling the material composition.

The VSP-P1 nanoprinting deposition system provides a revolutionary solution for gas sensor manufacturing based on two core technologies: Spark Ablation and Inertial Impact Printing

1. Spark erosionBy using high-voltage spark ablation to instantaneously vaporize metal electrodes, ultra pure nanoparticles (NPs) are generated, which can be flexibly mixed with metal oxides such as SnO ₂ NiO）、 Materials such as precious metal catalysts (such as Ag) enable customized nano porous layers (NPL).

2. Inertial impact printingHigh speed deposition of nanoparticles on sensor substrates can achieve patterned deposition without the need for photolithography or etching processes. The entire process avoids chemical pollution, ensures high purity and consistency of materials, and significantly improves sensor performance.

Part 02.High throughput, multi-component rapid screening of metal/oxide gas sensing coatings

In this case, nano porous layers (NPLs) based on metal oxide semiconductors (MOS) and metal catalysts were deposited on a multi-sensor array platform by printing, and toluene and formaldehyde were used as target gases for testing. Up to three different components of NPLs are used as the sensing layer. Starting from key performance indicators such as sensitivity, selectivity, response/recovery time, and detection limit (LOD), the study systematically analyzed the influence of material composition on gas sensing performance.

Part 03.Nano porous gas sensing layer deposition service: rapidly creating high-performance sensing materials
