  • Clinical Perspectives in Upper Limb Prostheses: An Update
    Current Surgery Reports, 2019
    Co-Authors: Aidan D. Roche, Ben Lakey, Irene Mendez, Ivan Vujaklija, Dario Farina, Oskar C Aszmann
    Abstract:

    This paper aims to summarise the development trends in upper limb Bionics over the past 5 years. Increasingly pattern recognition and regression control algorithms are being used to decode EMG signals for prosthetic control and are moving towards clinically available devices. Additionally, bionic reconstruction has built on the principles of targeted muscle reinnervation to add another rung to the reconstructive ladder for upper limb deficits. Finally, novel methods to provide sensation to prostheses are trialled not just in the laboratory but in home testing systems as well. Engineering, surgical and rehabilitation methods are gradually adding more capabilities to modern prostheses, moving towards the goal of replicating natural hand function.

  • research and application conceptual integrated model based on triz and Bionics for product innovation
    International Journal on Interactive Design and Manufacturing (ijidem), 2017
    Co-Authors: Liu Xiaomin, Huang Shuiping, Chen Yuting
    Abstract:

    TRIZ and Bionics are two techniques for systematic innovation that can help designers achieve innovative product solutions. In order to help the designer to determine conflicts happened in the design of product, an adapted TRIZ method is proposed. Bionics is a new developing frontier science permeating and combine biology, mathematics and engineering studies, and the designer can attain a innovative solution by adapting Bionics method. This paper describes a interactive model by integrating TRIZ tools with coupling Bionics. Firstly, a new table of inventive principles based on biological function is presented, and the human–computer interaction query interface was designed by MATLAB tool. After design conflicts in product system are determined, designer or group of ideation chooses from the bionic template which is attained according to the conflict Matrix 2003 in TRIZ, The biological tree model is built to analyze biological coupling elements of the bionic template, and then analytic hierarchy process is applied to figure out the main and hypo-main coupling elements. By imitating functions of the main and hypo-main coupling elements, different kinds of bionic coupling models for product can be established. Finally, the designer can evaluate and judge whether the innovative solution is optimal or should be returned to design.

  • A pneumatic bionic voice prosthesis : pre-clinical trials of controlling the voice onset and offset
    U.S. Public Library of Science, 2018
    Co-Authors: Ahmadi Farzaneh, Noorian Farzad, Novakovic Daniel, Schaik, Andre Van
    Abstract:

    Despite emergent progress in many fields of Bionics, a functional Bionic Voice prosthesis for laryngectomy patients (larynx amputees) has not yet been achieved, leading to a lifetime of vocal disability for these patients. This study introduces a novel framework of Pneumatic Bionic Voice Prostheses as an electronic adaptation of the Pneumatic Artificial Larynx (PAL) device. The PAL is a non-invasive mechanical voice source, driven exclusively by respiration with an exceptionally high voice quality, comparable to the existing gold standard of Tracheoesophageal (TE) voice prosthesis. Following PAL design closely as the reference, Pneumatic Bionic Voice Prostheses seem to have a strong potential to substitute the existing gold standard by generating a similar voice quality while remaining non-invasive and non-surgical. This paper designs the first Pneumatic Bionic Voice prosthesis and evaluates its onset and offset control against the PAL device through pre-clinical trials on one laryngectomy patient. The evaluation on a database of more than five hours of continuous/isolated speech recordings shows a close match between the onset/offset control of the Pneumatic Bionic Voice and the PAL with an accuracy of 98.45 ±0.54%. When implemented in real-time, the Pneumatic Bionic Voice prosthesis controller has an average onset/offset delay of 10 milliseconds compared to the PAL. Hence it addresses a major disadvantage of previous electronic voice prostheses, including myoelectric Bionic Voice, in meeting the short time-frames of controlling the onset/offset of the voice in continuous speech

  • Bionics in patents – semantic-based analysis for the exploitation of bionic principles in patents
    Procedia Engineering, 2011
    Co-Authors: Lothar Walter, Ralf Isenmann, Martin G. Moehrle
    Abstract:

    In this paper we present a sophisticated method to exploit bionic inventions in patents with the help of semantic patent analysis. This method enables users to visualize similarities in patent content in a semantic patent map. These maps could be used for strategic decision-making, e.g. for developing technologies and commercial usage and – no less important – for providing new insights to researchers and practitioners involved in Bionics. A case study of US-based patents between 1976 and 2006 clearly shows that most bionic inventions are patented as medical applications in the area of surgery. Other fields of technological applications, however, apparently do not make use of bionic ideas for solving inventive problems. As a result, Bionics may provide great potential for solving technical problems that needs to be exploited, e.g. perhaps to be carried out with the help of TRIZ.
