Capacitive sensor for respiration monitoring
2015 IEEE Sensors Applications Symposium (SAS), 2015Respiration monitoring of patients with chronic diseases, children, elderly, or sportsmen can be a useful tool in health condition assessment, early diagnosis of various diseases, and real-time prediction of possibly dangerous health conditions. In this paper we present a low-cost solution of respiration monitoring system, based on a custom designed ...

2009 32nd International Spring Seminar on Electronics Technology, 2009
This paper is focused on a cavity in LTCC (Low Temperature Co-fired Ceramics), which is one of the methods used for creation of pressure sensor. The mechanical part is 3D structure in which there are integrated electrodes created by TFT (Thick Film Technology). One of them is fixed and the other one is on the deformation element.

A High-Accuracy Capacitance-to-Voltage Converter for Capacitive Sensors
2020 IEEE 11th Latin American Symposium on Circuits & Systems (LASCAS), 2020A switched-capacitor (SC) capacitance-to-time (C/T) converter used for differential capacitive sensors with improved accuracy is presented in this paper. Using three rather than two time intervals, the circuit can remove the influences of the propagation delay of the comparator the channel charge injection and clock feedthrough due to analog switches ...

Determination of the theoretical capacitance of a concave capacitance sensor
Review of Scientific Instruments, 1979The practical use of four concave capacitance plates for determining in situ volume fractions in two-phase pipelines has been amply demonstrated. In this letter, the system is analyzed theoretically using a microstrip technique and the results are compared with experimental data.

Unique and Unclonable Capacitive Sensors
IEEE Sensors Journal, 2018Inspired from nature, a new concept called 'sensors with unique and unclonable characteristic', has been developed. Such sensors respond to a measurand and provide a unique output. Random variations in the structure of the sensors are responsible for these unique characteristic.

A Smart Capacitive Angle Sensor
IEEE Transactions on Industrial Informatics, 2005This paper presents a smart capacitive angle sensor suited for automotive and industrial use. To comply with tough constraints of such applications in terms of environmental conditions, unit costs, and physical size, a fully integrated solution is mandatory.

An accurate interface for capacitive sensors
IEEE Transactions on Instrumentation and Measurement, 2002A new smart interface based on a first-order charge-balanced SC-oscillator is presented for capacitive sensors, which are shunted by a parasitic conductance. In the novel interface, the effect of shunting conductance is reduced by using the charge/discharge method.

Microelectronics International, 2018
Purpose The purpose of this paper is to analyse the possibilities of mechanical switch replacement by capacitive film touch sensor in applications requiring high reliability and short response time. Advantage of replacing mechanical switch by capacitive touch sensor is no mechanical wear and possible implementation of sensor in application where the ...

Elastomeric capacitive sensors
2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, 2011Elastomers are emerging as an alternative to inorganic materials for electromechanical transducers. The rubber-like polymers are characterized by high elasticity (their equivalent elastic modulus is typically 2 orders of magnitude lower than that of silicon) and high yield strain (>100%).
