NaugaNeedles' Ultra Sharp NanoProbe (USNP)
Advantages compare with standard tungsten probes:
A comparison between mechanical properties of the USSP and standard tungsten probes:
Due to crystallinity of their tip, the USNPs have excellent mechanical properties. SEM images shown below demonstrate the USNP's excellent mechanical properties. Figure 1a shows the SEM images of a USNP as it is pushed against a silicon surface. Despite standard tungsten probes that are plastically deformed (Figure 1b), the USSPs can be elastically deformed up to 50% of their length and return to the original shape without any plastic deformation.
