FORCE SENSING DEVICES WITH MULTIPLE FILLED AND/OR EMPTY CHANNELS AND OTHER ATTRIBUTES
A nanoscale force sensing device includes a probe having a tip with multiple isolated channels (1.1 and 1.2) formed with a tapered (1.3) or untapered (1.4) structure such that two or more materials (solid, liquid or gas) of either the same or different chemical composition are isolated from one another by a solid material, or till (1.5). The device may be either straight or cantilevered and may be mounted to permit detection of surface forces while performing other functions at the same time.
