Design and fabrication of flexible tactile sensing and feedback interface for communication by deafblind people

Humans generally interact and communicate using five basic sensory modalities and mainly through vision, touch and audio. However, this does not work for deafblind people as they have both impaired hearing and vision modalities, and hence rely on touch-sensing. This necessitates the development of alternative means that allows them to independently interact and communicate. To do this requires a solution which has the capability for tactile sensing and feedback. Therefore, tactile interface becomes a critical component of any assistive device usable by deafblind people for interaction and communication. Given that existing solutions mainly use rigid and commercial components, there is a need to tap into the advancements in flexible electronics in order develop more effective and conformable solutions. This research involves the development of flexible tactile communication interface usable in assistive communication devices for deafblind people. First, commercial sensors and actuators were utilised as a proof-of-concept and then four novel tactile interfaces were explored which include two similar touch-sensitive electromagnetic actuators, one capacitive tactile sensing array, and a facile flexible inductance-based pressure sensor. The two fabricated touch-sensitive electromagnetic actuators (Type 1 and 2) are both based on electromagnetic principle and capable of simultaneous tactile sensing and feedback. Each comprises of a tandem combination of two main modules - the touch-sensing and the actuation module, with both modules integrated as a single device in each case. The actuation module employs a flexible planar spiral coil and a Neodymium magnet assembled in a soft Polydimethylsiloxane (PDMS) structure, while the touch-sensing module is a planar capacitive metal- insulator-metal structure of copper. The flexible coil (~17µm thick and with 45 turns) was fabricated on a Polyimide sheet using Lithographie Galvanoformung Abformung (LIGA) process. The results of characterisation of these actuators at frequencies ranging from 10Hz to 200Hz, shows a maximum displacement (~ 190µm) around 40Hz. Evaluation of this by 40 (20 deafblind and 20 sighted and hearing) participants show that they can feel vibration at this range. Another tactile interface fabricated is an 8 x 8 capacitive tactile sensing array. The sensor was developed on a flexible Polyvinyl Chloride (PVC) sheet with column electrodes deposited on one side and row electrodes on the reverse side. It is intended for use as an assistive tactile communication interface for deafblind people who communicate using deafblind manual alphabets as well as the English block letters. An inductance-based pressure sensor was also designed, fabricated and characterised for use as an input interface for finger Braille as well as other tactile communication methods for deafblind people. It was realised with a soft ferromagnetic elastomer and a 17µm-thick coil fabricated on a flexible 50 µm-thick polyimide sheet. The ferromagnetic elastomer acts as the core of the coil, which when pressed, sees the metal particles moving closer to each other, leading to changes in the inductance. The coil, with 75µm conductor and 25µm pitch, was also realised using LIGA micromolding technique. Seven different sensors were fabricated using different ratios (1:1, 1:2, 1:3, 1:5, 2:1, 3:1, and 5:1) of Ecoflex to Iron particles. The performance of each sensor was investigated and generally, sensors with higher Iron particles gave better sensitivity, linear as well as dynamic range. In comparison with all other fabricated sensors, the sensor made with 1:5DD was recommended for application as a tactile interface

This book brings together all 16 articles published in the Special Issue "Applied Mathematics to Mechanisms and Machines" of the MDPI Mathematics journal, in the section “Engineering Mathematics”. The subject matter covered by these works is varied, but they all have mechanisms as the object of study and mathematics as the basis of the methodology used. In fact, the synthesis, design and optimization of mechanisms, robotics, automotives, maintenance 4.0, machine vibrations, control, biomechanics and medical devices are among the topics covered in this book. This volume may be of interest to all who work in the field of mechanism and machine science and we hope that it will contribute to the development of both mechanical engineering and applied mathematics
