Flexible pressure sensors usually exhibit high sensitivity, excellent resolution, and can be mass-produced. Herein, a high-resolution, capacitive, paper-based, 3D-printed sensor with simple, low-cost preparation method is proposed. The has wide detection range (300–44,000 Pa), short response time (<50 ms), mechanical stability during repeated loading/unloading (3750 Pa). It measure the weigh...

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...

Based on a capacitive angle and angular rate sensor, a sensor measuring the relative angle between two rotating shafts has been developed. Two rotatable electrodes are placed between two sensor plates. The relative angle between the two rotors and the absolute position of the rotor blades are calculated from measurements of the capacitive coupling between different transmitting stator segments ...

We report fabrication and characterization of a new hydrogel-based microsensor for wireless chemical monitoring. The basic device structure is a high-sensitivity capacitive pressure sensor coupled to a stimuli-sensitive hydrogel that is confined between a stiff porous membrane and a thin glass diaphragm. As small molecules pass through the porous membrane, the hydrogel swells and deflects the d...

In this paper we investigate a short range capacitive proximity sensor as complementary sensor system in situations, where conventional optical based sensor systems have short comings, e.g., due to space requirements. In the presented collision avoidance scenario it can be used even without any vision or Lidar based sensor system. Our sensor is capable of detecting humans and objects made of co...

Flexible Pressure Sensors Inspired by splashed particles from laser processing, in article number 2207362, Liang Guo and co-workers propose a method for mold/mask-free fabrication of microstructured flexible electrodes femtosecond laser-activated metal deposition. The capacitive pressure sensor with such presents outstanding performance can be easily made into arrays spatial mapping.

Three-layered electrode structures are often employed in multiple-electrode capacitive position sensors. Even when advanced algorithms and well-designed guarding electrodes are used, the electric-field-bending effect is still one of the major contributors to the nonlinearity of capacitive position sensors. In this paper, the effects of electric-field bending on linearities of five capacitive li...

Flexible pressure sensors are essential components of electronic skins for future attractive applications ranging from human healthcare monitoring to biomedical diagnostics, robotic skins, and prosthetic limbs. Here we report a new kind of flexible pressure sensor. The sensors are capacitive, and composed of two Ag wrinkled electrodes separated by a carbon nanotubes (CNTs)/polydimethylsiloxane ...
