Having intellectual property in micro and nano metal fabrication, the firm specializes in titanium alloys, to construct metal-based micro devices. Unique to the industry, Pi-MEMS uses titanium as a bulk substrate thus producing hardier devices. The company's patented technology allows the construction of ultra-thin, lightweight, and complex MEMS. Due to titanium being generally accepted as being biologically safe, PiMEMS' products have applications in the biomedical field.
