Simplifying Capacitive Sensor Readout Using a New Direct Interface Circuit
Hidalgo-López, José Antonio
; Castellanos-Ramos, Julián (IEEE, 2022)
Direct interface circuits (DICs) are efficient for reading resistive, capacitive, or inductive sensors in a digital format. The simplest DICs consist of just a few passive elements that connect a digital processor (DP) to ... -
Tactile Sensors Based on Conductive Polymers
Macicior, Haritz; Sikora, Tomasz; Ochoteco, Estíbalitz; Castellanos-Ramos, Julián; Navas-González, Rafael Jesús; Vidal-Verdú, Fernando[et al.] (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 ... -
Three Realizations and Comparison of Hardware for Piezoresistive Tactile Sensors
Vidal-Verdú, Fernando; Oballe-Peinado, Óscar; Sánchez-Durán, José Antonio; Castellanos-Ramos, Julián; Navas-González, Rafael Jesús (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 ... -
Tri-axial tactile sensing element.
A 13 x 13 square millimetre tri-axial taxel is presented which is suitable for some medical applications. Finite Element Analysis is carried out to determine what structure is the best to obtain a uniform distribution of ... -
Two proposals to simplify resistive sensor readout based on Resistance-to-Time-to-Digital conversion
Hidalgo-López, José Antonio; Castellanos-Ramos, Julián (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 ... -
Two-capacitor direct interface circuit for resistive sensor measurements
Hidalgo-López, José Antonio; Oballe-Peinado, Óscar; Castellanos-Ramos, Julián; Sánchez-Durán, José Antonio (MDPI, 2021-02-22)
Direct interface circuits (DICs) avoid the need for signal conditioning circuits and analog- to-digital converters (ADCs) to obtain digital measurements of resistive sensors using only a few passive elements. However, such ... -
Wide range calibration method for direct interface circuits and application to resistive force sensors
Hidalgo-López, José Antonio; Oballe-Peinado, Óscar; Castellanos-Ramos, Julián; Tejero-Calado, Juan Carlos; Vidal-Verdú, Fernando (Institute of Electrical and Electronics Engineers, 2021-10-15)
A novel approach to interface resistive sensors directly to a Field Programmable Gate Array (FPGA) is presented in this paper. The circuit is based on Direct Interface Circuits (DICs), which make the sensor reading through ...
