The paper reports on a nonlinear frequency up-converting vibration energy harvester with enhanced broadband performance below 50 Hz, which is attained by leveraging vibro-impact interaction between two high-frequency piezoelectric generators and two low-fr ...
The Alfven Eigenmode Active Diagnostic system (AEAD) has undergone a major upgrade and redesign to provide a state-of-the-art excitation and real-time detection system for JET. The new system consists of individual 4 kW amplifiers allowing for increased cu ...
In Atomic force microscopy (AFM), the tip-sample interaction force can be measured
through two primary detection techniques: optical beam detection (OBD) and electrical (self-sensing)
readout. Compared to the optical method, the convenience of the self-sen ...
