Capacitive sensing of the electrocardiogram allows inconspicuous monitoring of the most well-known electrophysiological signal. Wheelchair users with cardiac maladies would benefit from ECG unobtrusive monitoring. However, motion and daily life activities impose strong artifacts to the signal acquired. This study aims at the extended capacitive electrocardiogram acquisition with and without mov...

This paper reports the design and fabrication of capacitive silicon nanomechanical resonators with the selective vibration of a high-order mode. Fixed-fixed beam capacitive silicon resonators have been successfully produced by the use of electron beam lithography, photolithography, deep reactive ion etching, and anodic bonding methods. All resonators with different vibration modes are designed ...

This study looks at two ways of extracting a glottal waveform from recorded speech. One way is to inverse filter the flow at the mouth. Another is to inverse filter the microphone signal. Theoretically, the microphone signal is considered to be the equivalent of a first order differentiation of the flow signal recorded at the lips. Recording the oral airflow is more complicated than the recordi...
