RESUMO
The study of swimming behavior is an important part of fish biology research and the swim tunnel is used to study swimming performance as well as metabolism of fish. In this investigation, we have developed a user-friendly, automated, modular, and low-cost swim tunnel that permits to study the performance of one or more fish separately, as well as a small group of individuals. To validate our swim tunnel, we assessed swimming activity of four different species (zebrafish, medaka, guppy, and cavefish) recording reliable data of swimming behavior and performance. Because swimming behavior has been recently used in different fields from physiology to ecotoxicology, our setup could help researchers with a low-cost solution.

The aim of the present paper is to illustrate the phases of design and application of an innovative input source for an EMG upper limb prosthetic arm: a laryngophone, otherwise called throat microphone (t-mic). In the last years several different input sources were explored, from the implantable myoelectric sensors to the mechanomyographic sensors. The idea of controlling a prosthesis with vocal commands is quite recent but seems to be promising in helping users to better control their devices, improving the quality of their life.
