Intraocular MEMS Capacitive Pressure Sensor
2021Microelectromechanical system (MEMS) sensors are suitable for measuring intraocular pressure (IOP). IOP measurement is useful for monitoring diseases such as glaucoma. The average pressure range for healthy persons is within 10–20 mmHg. A pressure beyond this range could damage the eye nerves and causes of blindness.

Transient response of capacitive pressure sensors
Sensors and Actuators A: Physical, 1992Abstract The responses of capacitive pressure sensors to step and impulse waveforms are computed for small deflections and low damping using the thin-plate theory. These sensors behave as second-order systems with one degree of freedom. From present and previous results, the expression of the transfer function is established.

A textile based capacitive pressure sensor
Proceedings of IEEE Sensors, 2003This paper introduces an approach for decoding the pressure information exerted over a broad piece of fabric by means of capacitive sensing. The proposed sensor includes a distributed passive array of capacitors (i.e. an array where no active elements are involved), whose capacitance depends on the pressure exerted on the textile surface, and an ...

Soft Capacitive Pressure Sensors: Trends, Challenges, and Perspectives
ACS Nano, 2022Soft pressure sensors are critical components of e-skins, which are playing an increasingly significant role in two burgeoning fields: soft robotics and bioelectronics. Capacitive pressure sensors (CPS) are popular given their mechanical flexibility, high sensitivity, and signal stability.

Capacitive Silicon Differential Pressure Sensor
Proceedings of the International Solid-State Sensors and Actuators Conference - TRANSDUCERS '95, 2005A capacitive differential pressure sensor based on silicon bulk micromachining is presented. This sensor, which is part of a flow metering system, transforms the differential pressure delivered by a fluidic oscillator into capacitance variations. These variations are then converted by an ASIC into a digital output signal.

Performance Optimization of a Capacitive Pressure Sensor
Key Engineering Materials, 2015In this paper, the thermo-mechanical modelling of an entire sensor structure, under hydrostatic pressure, is carried out using commercial FEM software COMSOL multiphysics. A comparison of the obtained results with those found in the literature, allows us to corroborate the well-known models.

Catheter‐tip capacitive pressure sensor
Electronics and Communications in Japan (Part II: Electronics), 1990AbstractAs a pressure sensor to be used at the tip of a catheter, a capacitive relative pressure sensor was fabricated. This paper describes the fabrication process and the characteristics of this pressure sensor.The size of the sensor fabricated is 0.7 × 3.5 × 0.8 mm3 and the spacing between the capacitor electrodes is either 1.0 μm or 1.5 μm.

Touch mode capacitive pressure sensors
Sensors and Actuators A: Physical, 1999Touch mode capacitive pressure sensors offer better performance in industrial applications than other devices. In touch mode operation, the diaphragm of the capacitive pressure sensor touches the substrate structure in operation range. The advantages of this mode of operation are near-linear output characteristics, large over-range pressure and robust ...

Miniature polymer capacitive pressure sensor
Proceedings 2007 IEEE SoutheastCon, 2007This paper describes the development of a miniaturized pressure sensing device made of polymer materials. An all-polymer design imparts a high degree of physical flexibility, if required, and makes the device very lightweight. The use of moldable polymers for the device components allows the rapid prototyping of this device, cutting down production ...
