Electrical feedthrough governs symmetry of phononic frequency combs in MEMS resonators

Understanding parasitic electrical feedthrough in microelectromechanical (MEMS) resonators is essential for controlling nonlinear spectral phenomena. Here, we demonstrate that electrical feedthrough fundamentally governs the symmetry of phononic frequency combs in a capacitively...

Platinum-nanostructured silicon microneedles with scalable fabrication for EEG biosensing

This study details the development and characterization of a silicon microneedle electrode array for enhanced biopotential recording. Fabricated using a streamlined two-step process, the device design was guided by mechanical analysis to ensure structural stability and minimize s...
