Forearm Motion Recognition With Noncontact Capacitive Sensing

Enhancing Accelerometer-Based Activity Recognition with Capacitive Proximity Sensing

Activity recognition with a wearable accelerometer is a common investigated research topic and enables the detection of basic activities like sitting, walking or standing. Recent work in this area adds different sensing modalities to the inertial data to collect more information of the user’s environment to boost activity recognition for more challenging activities. This work presents a sensor ...

Pervasive Activity Detection with Capacitive Sensing

This paper presents a toolkit for realizing capacitive sensing applications for human-computer interaction in pervasive computing systems. We describe the CapSenseToolkit, a complete toolkit for prototyping and implementing systems for detecting presence of humans and objects and for integrating 3D interaction with everyday objects. This allows to acquire data and develop sophisticated algorith...

Active Capacitive Sensing: Exploring a New Wearable Sensing Modality for Activity Recognition

The paper describes the concept, implementation, and evaluation of a new on-body capacitive sensing approach to derive activity related information. Using conductive textile based electrodes that are easy to integrate in garments, we measure changes in capacitance inside the human body. Such changes are related to motions and shape changes of muscle, skin, and other tissue, which can in turn be...

Droplet-based interfacial capacitive sensing.

This paper presented a novel droplet-based pressure sensor using elastic and capacitive electrode-electrolyte interfaces to achieve ultrahigh mechanical-to-electrical sensitivity (1.58 μF kPa(-1)) and resolution (1.8 Pa) with a simple device architecture. The miniature transparent droplet sensors, fabricated by one-step laser micromachining, consisted of two flexible polymer membranes with cond...
