Unobtrusive and continuous monitoring of vital signs is becoming more and more important
both for patient monitoring in the home environment and for sports activity tracking. Even …

Impedance plethysmography is a technique that allows monitoring changes in the volume of
specific tissues or organs inside the human body, through the measurement of variations in …

In this paper, we present an approach to sense human body capacitance and apply it to
recognize lower limb locomotion modes. The proposed wearable sensing system includes …

Continuous monitoring of respiratory rate is crucial in forecasting health crises and other
major physiological instabilities. Current respiratory monitoring methods limit the mobility of …

Respiratory rate is a critical vital sign that indicates health condition, sleep quality, and
exercise intensity. This paper presents a non-invasive, ultra-low-power, and cost-effective …

We present a methodology and a circuit to extract liquid resistance and capacitance
simultaneously from the same output signal using interdigitated sensing electrodes. The …

A new approach to monitoring respiration activity for first responders is proposed. This
approach emphasizes low cost and portability. Current commercial methods cost upwards of …

In this paper, we present a methodology and a circuit to extract liquid mixtures resistance
and capacitance simultaneously from the same output signal using interdigitated sensing …

The contents of the present thesis relate the design, characterization, and integration of
sensing systems in order to obtain portable, simple, and power efficient solutions. A …

This work presents a methodology for the design of a time-domain capacitance-to-digital
converter in an IoT context. We explore the two types of capacitance-to-digital converters in …
