Abstract

This paper reports a new microforce generating machine under development at NMIJ, AIST. We proposed a new microforce generating method by referring to the principle of the Kibble balance experiment and planned to apply it to a rotary type machine. Microforce in the micronewton and millinewton range can precisely be generated using this newly developed machine.

Highlights

Microforce measurements in the micronewton and millinewton range have been applied in many industries and research fields, and the reliability of these measurements becomes essential, for example, for the evaluation of material mechanical property using an atomic force microscope (AFM)
Several national metrology institutes (NMIs) have developed various facilities, including microforce comparators that use the principle of the electromagnetic balance, to establish the traceability of microforce [1,2,3]
By referring to the principle of Kibble balance experiment [5, 6], and an electromagnetic force type torque standard machine developed in National Metrology Institute of Japan (NMIJ) [7], we proposed a new microforce generating method using electromagnetic force and planned to apply it to a rotary type machine

INTRODUCTION

Microforce measurements in the micronewton and millinewton range have been applied in many industries and research fields, and the reliability of these measurements becomes essential, for example, for the evaluation of material mechanical property using an atomic force microscope (AFM). Several national metrology institutes (NMIs) have developed various facilities, including microforce comparators that use the principle of the electromagnetic balance, to establish the traceability of microforce [1,2,3]. The National Metrology Institute of Japan (NMIJ), National Institute of Advanced Industrial Science and Technology (AIST), has developed a 2 N deadweight type force standard machine that uses gravity force and can extend the Japanese force standard down to 10 mN [4]. By referring to the principle of Kibble balance experiment [5, 6], and an electromagnetic force type torque standard machine developed in NMIJ [7], we proposed a new microforce generating method using electromagnetic force and planned to apply it to a rotary type machine
