Capacitive CO 2 Sensor †

The objective of the present paper is to provide a concept for a chemical sensor having a small size, a low power consumption and a high reliability for sensing CO2 under different humidity levels at atmospheric pressure, while maintaining a long term stability under working conditions. A high temperature regeneration process of the sensing layer is unneeded to ensure a long term stability of t...

Multi-Channel Capacitive Sensor Arrays

In this paper, multi-channel capacitive sensor arrays based on microstrip band-stop filters are studied. The sensor arrays can be used to detect the proximity of objects at different positions and directions. Each capacitive sensing structure in the array is connected to an inductive element to form resonance at different frequencies. The resonances are designed to be isolated in the frequency ...

Embedded Distributed Capacitive Tactile Sensor

A novel embedded distributed capacitive tactile sensor system designed to be installed on humanoid robots is presented. It provides pressure and shape information about the contacts with objects and the environment. The system is based on conformable mesh of sensors having triangular shape, interconnected in order to form a networked structure. Each triangle is a flexible substrate allowing the...
