Benefits of technology

This patented describes an approach called making small metal particles on top of another tiny wire mesh made from carbon fiber or other fibers with high electrical conductivity. These tiny wires are then used to create sensory devices like electronic noses (electronic nose). By adjusting how much silver paste was added during this process, it becomes possible to control the size of these tiny metallic structures while maintaining their ability to transmit light through them. Overall, this technology allows for quick production of highly sensitive sensor elements without adding too many expensive components such as gold plating layers.

Problems solved by technology

This patented technical problem addressed in this patents relates to developing an effective way to prepare nano porous materials that can be easily integrated into biological sensing devices without compromising their performance or durability over time.
