I am exploring the possibility of using non-invasive capacitive sensing techniques to detect carotid artery stenosis.

The idea is to measure electrical capacitance changes caused by variations in blood volume and vessel wall properties during the cardiac cycle. Since stenosis alters blood flow and vessel compliance, these changes might reflect as measurable differences in capacitance.

I am interested in discussing:

• Whether such a capacitive method can provide clinically significant accuracy for detecting stenosis
• Challenges in isolating capacitance signals from surrounding tissues and motion artifacts
• Any published work or experimental results on capacitive or impedance-based detection of atherosclerosis/stenosis

I welcome insights from researchers working in biomedical instrumentation, signal processing, and cardiovascular diagnostics.
