A microgripper capable of accurately releasing or clamping the microgold wire for ultrasonic bonding is a key component in integrated circuit and light-emitting diode wire bonders. A novel gripper ...

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 ...

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 ...

Vibration energy harvesting with piezoelectric materials is of practical interest because of the demand for wireless sensing devices and low-power portable electronics without external power supply.
