This paper presents a method of simulating capacitive sensor using COMSOL Multiphysics. A petal-form sensitive electrode structure applied to angle was simulated software; the calculated sines and cosines with capacitance value fill in simulation sensor. First, according construction principle structure, GeoGebra graphing calculator theoretical analysis expression function used obtain two-dimen...

Capacitive sensors in both touch and proximity varieties are becoming more common in many industrial and research applications. Each sensor requires one or more electrodes to create an electric field and measure changes thereof. The design and layout of those electrodes is crucial when designing applications and systems. It can influence range, detectable objects, or refresh rate. In the last y...

Kalimbo is an extended kalimba, built from repurposed materials and fitted with sensors that enable it to function as a reductionist control interface through physical gestures and capacitive sensing. The work demonstrates an attempt to apply theories and techniques from visual collage art to the concept of musical performance ecologies. The body of the instrument emerged from material-led maki...

We have created a new electronic musical instrument, referred to as the Termenova (Russian for “daughter of Theremin”) that combines a free-gesture capacitivesensing device with an optical sensing system that detects the reflection of a hand when it intersects a beam of an array of red lasers. The laser beams, which are made visible by a thin layer of theatrical mist, provide visual feedback an...

We study the feasibility of leveraging the sensors embedded on mobile devices to enable a user authentication mechanism that is easy for users to perform, but hard for attackers to bypass. The proposed approach lies on the fact that users perform gestures in a unique way that depends on how they hold the phone, and on their hand’s geometry, size, and flexibility. Based on this observation, we i...

This paper addresses the challenges related to the design of a high-resolution, low-latency capacitive displacement sensor. An auto-alignment mechanism of the sensor head is proposed which relaxes the resolution requirement of the readout circuit. Different interfacing principles are investigated and analyzed, and the advantage of using a switched-capacitor readout topology for a specific appli...

Reliable hermetic packaging of microelectromechanical system (MEMS) pressure sensor arrays for underwater applications always presents a formidable challenge, which is further compounded by the unforgiving harsh sea environments, during the design, fabrication and characterization stages of the sensor arrays. As such, a flexible underwater diaphragm-based pressure sensor array packaging scheme ...
