Yes, tungsten needles can be used for MEMS (micro-electro-mechanical systems) applications. MEMS devices are typically fabricated using microfabrication techniques such as photolithography, etching, and deposition, and tungsten needles can be used for tasks such as probing, cutting, and depositing materials with high precision in these processes. The high strength, hardness, and thermal stability of tungsten make it a suitable material for MEMS applications where precision and durability are important.
