Patent number: 7654159Abstract: A force sensor (200) and nanoidenation system (300) using such force sensor (200), wherein the force sensor (200) comprise a movable membrane (207) attached to a fixed bulk structure (210) with springs (201, 202, 203, 204) formed between the membrane (207) and bulk structure (210); the springs (201, 202, 203, 204) may be provided two on each side of a rectangular membrane(207) and each in the form of a U-shape with displacing elements (801) formed perpendicular to each open end of each U-shaped spring (800). The force sensor further comprises electrodes (206) for detecting capacitive changes between the movable membrane (207) and the electrodes (206) in order to measure a movement in relation to an applied force. The membrane (207) further comprises a probe holding structure (214) for providing a solution for interchangeable probes (211).Type: GrantFiled: January 26, 2005Date of Patent: February 2, 2010Assignee: Nanofactory Instruments ABInventors: Peter Enoksson, Alexandra Nafari, Håkan Olin, Fredrik Althoff, Andrey Danilov, Jens Dahlström

Patent number: 7586105Abstract: The present invention relates to a device and system from doing mechanical and electrical measurements and manipulation on nano or micro sized objects using a sample holder adapted to fit in situ of a transmission electron microscope. The sample holder comprise at least two arms each with at least one connector whereby the sample (206) may be mounted between the two connectors forming a bridge closing a gap between the two arms of the sample holder. The sample holder is arranged to provide mechanical forces to a sample mounted on the sample holder and measuring and/or applying electrical signals from the sample while at the same imaging using the transmission electron microscope. Each arm of the sample holder may comprise three substantially parallel beams for electro-thermal actuation.Type: GrantFiled: April 19, 2007Date of Patent: September 8, 2009Assignee: Nanofactory Instruments ABInventor: Kristian Molhave

Patent number: 7363802Abstract: This invention relates to a measurement device for use in an electron microscope. The device comprises a sample holder, for holding a sample to be studied, and an indentation tip, being arranged in proximity of the sample holder, whereby an interaction between the sample and the tip is arranged to be measured. The measurement device comprises a force sensor being positioned in proximity with an interaction area of the sample and the tip and is arranged to directly measure a force resulting from interaction between the sample and the tip.Type: GrantFiled: May 12, 2004Date of Patent: April 29, 2008Assignee: Nanofactory Instruments ABInventors: Håkan Olin, Krister Svensson, Fredrik Althoff, Andrey Danilov

Patent number: 6917140Abstract: This invention relates to a device for micropositioning of an object (4), e.g. for use in a microscope. The device comprises an acceleration unit (1) and an intermediate part (3), connecting said acceleration unit (1) with said object (4). The position of the object relative to the acceleration unit (1) is variable at high acceleration or retardation of said acceleration unit (1), owing to mechanical inertia of the object (4). Further, the intermediate part (3) has a first end (3?), being attached to said acceleration unit (1), and a second end (3?), being provided with an essentially circumferential contact surface (3a), and the object (4) is provided with clamping elements (4?). These clamping elements (4?) are adapted to clamp around said contact surface (3a) of said intermediate part (3) in order to hold the object (4) in relation to the intermediate part (3) merely by the clamping force and the frictional force exerted by said clamping elements (4?) upon said contact surface (3a).Type: GrantFiled: December 3, 2001Date of Patent: July 12, 2005Assignee: Nanofactory Instruments ABInventors: Håkan Olin, Fredik Althoff, Krister Svensson

Patent number: 6452307Abstract: The invention relates to a device for micropositioning of objects, for example, in microscopy. The device comprises an accelerating means and a positioning unit connected therewith and connected with the object. The position of the object relative to the positioning unit can be changed at high acceleration or retardation of the accelerating means owing to mechanical inertia of the object. The positioning unit comprises at least two clamping elements between which the object is intended to be held merely by the clamping force and the frictional force exerted by these clamping elements.Type: GrantFiled: January 11, 2002Date of Patent: September 17, 2002Assignee: Nanofactory Instruments ABInventors: Hakan Olin, Kristian Gustavsson, Per Gralvik
