Currently, voice rehabilitation of larynx cancer patients is performed by inserting a one-way shunt valve between trachea and oesophagus that prevents food and liquid from entering the trachea. Pressing the tracheal opening with a finger forces exhaled air through the shunt valve to the oesophagus, where soft tissue structures serve as a substitute voice. However, the voice is in many cases of poor quality and the process creates a mental barrier during speaking, as patients have to literally point at their handicap.
The NEWVOICE project aims to improve the quality of life for laryngectomees by developing a new voice-producing shunt prosthesis that is able to produce a voice with sufficient loudness, adjustable fundamental frequency and natural intonation.
Dr. Bart Verkerke, Project Manager of the Department of BioMedical Engineering at the main partner, the University of Groningen, describes how the partners initiated this work in a previous EUREKA project. “Most of the NEWVOICE participants were involved in project E! 723 ARTIFICIAL LARYNX, during which we gained a lot of the expertise in medical devices to improve the rehabilitation process that will be used in this project.”

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
