Abstract: The mechanical model of a “Zâ€‌ type doubledecker ball bearing under the action of radial load is established in this paper on the basis of the Hertz contact theory. According to the security contact angle theory, the ...

Abstract: As a critical step to integrate micro-nano electronic components on the soft substrate, transfer printing allows the facile fabrication of flexible electronics. The key to a successful transfer printing process is to ...

Abstract: Autoeliminating clearance auxiliary bearing devices (ACABD) can automatically eliminate the protective clearance between the ball bearing's outer race and the ACABD's supports, thus recenter the rotor when active magnetic ...

Abstract: As a versatile yet simple technique, transfer printing has been widely explored for the heterogeneous integration of materials/structures, particularly important for the application in stretchable and transient electronics. ...
