A multiplexing architecture for mixed-signal CMOS fuzzy controllers
(Institution of Engineering and Technology, 1998)Limits to precision impose limits to the complexity of analog circuits, hence fuzzy analog controllers are usually oriented to fast low-power systems with low-medium complexity. This paper presents a strategy to preserve ... -
A Modular Programmable CMOS Analog Fuzzy Controller Chip
(IEEE Circuits and Systems Society, 1999)We present a highly modular fuzzy inference analog CMOS chip architecture with on-chip digital programmability. This chip consists of the interconnection of parameterized instances of two different kind of blocks, namely ... -
Three Realizations and Comparison of Hardware for Piezoresistive Tactile Sensors
(MDPI, 2001-03-17)Tactile sensors are basically arrays of force sensors that are intended to emulate the skin in applications such as assistive robotics. Local electronics are usually implemented to reduce errors and interference caused by ... -
Neuro-fuzzy chip to handle complex tasks with analog performance
(IEEE Computational Intelligence Society, 2003)This paper presents a mixed-signal neuro-fuzzy controller chip which, in terms of power consumption, input–output delay, and precision, performs as a fully analog implementation. However, it has much larger complexity ... -
Tactile Sensors Based on Conductive Polymers
(Springer Berlin / Heidelberg, 2010)This paper presents results from a selection of tactile sensors that have been designed and fabricated. These sensors are based on a common approach that consists in placing a sheet of piezoresistive material on the top ... -
A large area tactile sensor patch based on commercial force sensors
(MDPI, 2011)This paper reports the design of a tactile sensor patch to cover large areas of robots and machines that interact with human beings. Many devices have been proposed to meet such a demand. These realizations are mostly ... -
Insights into the Mechanical Behaviour of a Layered Flexible Tactile Sensor

Two proposals to simplify resistive sensor readout based on Resistance-to-Time-to-Digital conversion
(Elsevier, 2023)Direct Interface Circuits (DICs) are simple circuits used in readouts for all types of sensors. For resistive sensors, all DICs perform a resistance-to-time-to-digital conversion using just the sensor, some calibration ... -
Direct interface circuits for resistive sensors affected by lead wire resistances
(Elsevier, 2023-08)This article proposes two novel circuits for the digital readout of resistive sensors with parasitic series resistances caused by the lead wire needed to connect remote sensors. Both circuits are based on so-called direct ... -
An estimation of triaxial forces from normal stress tactile sensor arrays
(Elsevier, 2023-10-04)This work proposes a new method to find an optimal solution of the inverse problem of the Boussinesq equation for ill-posed problems, applicable in the reconstruction of triaxial forces for processing contact data in tactile ... -
