Spain’s micro and nanotechnology industry has reached a critical point where research, strategic international collaborations, and the integration of advanced technologies into mainstream industries have led to a boom in the field. Spain has successfully carved a niche in this competitive field during a particularly challenging economic backdrop - a story that’s impressive and worth taking note of. One of Spain’s most notable contributions to the micro and nanotechnology industry lies in the advancements made by Graphenea, a graphene producer. The company has recently expanded its product portfolio to include suspended monolayer graphene on cavities, catering to the burgeoning field of nanoelectromechanical systems (NEMS). NEMS, often described as the smaller counterparts of microelectromechanical systems (MEMS), are rapidly being integrated into technologies such as optical switches, accelerometers, sensors, displays, and inkjet printers. At the core of NEMS are tiny vibrating membranes that must be both rigid and lightweight while possessing a high Young’s modulus—a set of properties that graphene embodies perfectly. Outside its borders, Spain has set its sights in cross-border collaboration and active participation in prestigious global platforms. At the Nanotech 2011 exhibition in Tokyo, the largest annual international nanotechnology event, Spain showcased advancements in the field with support from the Embassy of Spain, the Phantoms Foundation, and the Spanish Institute for Foreign Trade (ICEX). These collaborative efforts highlight Spain’s strategic focus on promoting its research and technological achievements on a global stage. Bilbao has emerged as a key location for nanotechnology discourse, hosting the second ImagineNano conference in April 2013. This event stood out by bringing together seven specialized conferences under one banner. Spain’s universities and research institutions play a pivotal role in advancing nanotechnology. At the Universidad Autónoma de Madrid, Spanish scientists collaborated with researchers from Germany and the United States to develop a nanothermometer capable of measuring heat dissipation in molecular-scale circuits.
