Wireless acoustic-driven current source achieving nanoampere-level at millimeter-scale
Piezoelectric surface acoustic wave devices can drive charge carriers in semiconductors through the acoustoelectric effect, generating direct currents with potential applications in sensing and biomedicine. However, current sources based on this mechanism that combine nanoampere-level precision, a wide dynamic range,...
