We demonstrated a wireless vibration sensing system powered by a piezoelectric vibration energy harvester (VEH). The VEH with an AlN piezoelectric film was fabricated using a standard semiconductor ...

Mammalian oocytes such as mouse oocytes have a highly elastic outer membrane, zona pellucida (ZP) that cannot be penetrated without significantly deforming the oocyte, even with a sharp micropipette.

By using piezoelectric actuators coupled to the tool-holder, one can choose to use different passive and active controls, generating a more versatile tool to control machining vibration. However, one ...
