Abstract: The present application discloses an inertial sensor comprising a proof mass, an anchor, a flexible member and several sensing electrodes. The anchor is positioned on one side of the sensing, mass block in a first axis. The flexible member is connected to the anchor point and extends along the first axis towards the proof mass to connect the proof mass, in which the several sensing electrodes are provided. In this way, the present application can effectively solve the problems of high difficulty in the production and assembly of inertial sensors and poor product reliability thereof.

Abstract: A binder composition for use in making metal parts via a metal powder injection molding process containing the following components: (a) a first polymer with a relatively low solubility parameter such as polyethylene and polypropylene; (b) a second polymer with a relatively high solubility parameter such as polystyrene and poly(methyl methacrylate); and (c) a block copolymer containing blocks of the first and second, or other structurally similar, constituting monomeric units. Examples of the block copolymers include ethylene/styrene copolymer, propylene/styrene copolymer, and isoprene/styrene copolymer, etc. The binder composition is dispersed in an appropriate dispersant, such as an oil or wax, then blended with a metal powder to form a metal powder injection composition. The metal powder injection composition forms a green compact with a predetermined shape and dimension using an injection molding machine. Finally the green compact is sintered to form the final product.
