A simulation of the muscle activation, contraction and movement is here presented. This system was developed based on the Bidomain mathematical model of the electrical propagation in muscles. This study shows an electrical stimuli input to a muscle and how this behave. The comparison between healthy subject and patient with muscle activation impairment is depicted, depending on whether the signal reaches a threshold. A 3D model of a bicep muscle and a forearm bone connected was constructed using OpenGL. This platform could be used for development of controllers for biomechatronic systems in future works...

Extensive literatures have shown approaches for decoding upper limb kinematics or muscle activity using multichannel cortical spike recordings toward brain machine interface (BMI) applications. However, similar topics regarding lower limb remain relatively scarce. We previously reported a system for training monkeys to perform visually guided stand and squat tasks. The current study, as a follow-up extension, investigates whether lower limb kinematics and muscle activity characterized by electromyography (EMG) signals during monkey performing stand/squat movements can be accurately decoded from neural spike trains in primary motor cortex (M1)...

This report compares wrist supination and pronation and flexion and extension movements with the common body-powered prosthesis and a new biomechatronics prosthesis with regard to patient satisfaction and problems experienced with the prosthesis. Fifteen subjects with traumatic transradial amputation who used both prosthetic systems participated in this study. Each subject completed two questionnaires to evaluate their satisfaction and problems experienced with the two prosthetic systems. Satisfaction and problems with the prosthetic's wrist movements were analyzed in terms of the following: supination and pronation; flexion and extension; appearance; sweating; wounds; pain; irritation; pistoning; smell; sound; durability; and the abilities to open a door, hold a cup, and pick up or place objects...

We present a novel example of a biomechatronic hybrid system. The living component of the system, embedded within microbial fuel cells, relies on the availability of food and water in order to produce electrical energy. The latter is essential to the operations of the mechatronic component, responsible for finding and collecting food and water, and for the execution of work. In simulation, we explore the behavioral and cognitive consequences of this symbiotic relation. In particular we highlight the importance of the integration of sensorimotor and metabolic signals within an evolutionary perspective, in order to create sound cognitive living technology...

Stem cell production systems need elaborate monitoring and control for meeting requirements on the final cell product. In this article, the use of biomechatronic design methodology for supporting these efforts is described. Biomechatronic design, which is based on a fundamental systematical design approach originating from mechanical engineering, is here applied for investigating how monitoring and control systems can be configured in stem cell manufacturing processes. Results are provided that demonstrate how the biomechatronic design tools are used to compare different process analytical instrumentation resulting in a design layout for the monitoring system for derivation of hepatocytes from human embryonic stem cells...

PURPOSE: This study examined the kinematic differences between a body-powered prosthesis and a biomechatronics prosthesis as a transradial amputee performed activities that involve flexion/extension and supination/pronation of the wrist. METHOD: The subject's wrist movements were calculated and compared as he completed a wrist range of motion test involving simulated flexion/extension and supination/pronation. RESULTS: The results revealed that, under the test conditions, the body-powered prosthesis limits an individual's ability to complete four different tasks of wrist movement especially when it comes to complete the supination/pronation movement...

Scale-up of cell culture bioreactors is a challenging engineering work that requires wide competence in cell biology, mechanical engineering and bioprocess design. In this article, a new approach for cell culture bioreactor scale-up is suggested that is based on biomechatronic design methodology. The approach differs from traditional biochemical engineering methodology by applying a sequential design procedure where the needs of the users and alternative design solutions are systematically analysed. The procedure is based on the biological and technical functions of the scaled-up bioreactor that are derived in functional maps, concept generation charts and scoring and interaction matrices...

Learning to grasp an object is an important milestone in neurological development during infancy. Several studies report development of reaching in infants but less attention is devoted to reaching with successful grasping and to development of grip force. This study investigates, in the first weeks of life, the development of palmar grasp both for assessment of unimanual/bimanual grasping actions in centrally and laterally placed objects and for measurement of exerted power grip force. We longitudinally examined ten infants from 18 weeks to 41 weeks, at 2-weeks intervals, with a toy placed in three positions (body midline, ipsilateral and contralateral shoulder)...

BACKGROUND: Optical assistance in laparoscopic surgery is essential for an optimal procedure. Unlike conventional surgery, it requires new systems to reduce spatial location time, navigation and cleanliness without compromising surgical quality. This article shows the kinematic analysis of a new bio-mechatronic design to assist laparoscopic visual perspective in real time, either during training or in surgery. METHODS: The bio-mechatronic system is analyzed in order to get the kinematic model of the system...

The study and measurement of grasping actions and forces in humans is important in a variety of contexts. In infants, it can give insights on the typical and atypical motor development, while it poses functional and operative requirements that are not fully matched by current sensing technology. Novel approaches for measuring infants' grasping actions are based on sensorized platform usable in natural settings. A new set of instrumented toys has been designed for the assessment/stimulation of upper limbs of infants between 4 and 9 months...

Our vision of plants is changing dramatically: from insensitive and static objects to complex living beings able to sense the environment and to use the information collected to adapt their behaviour. At all times humans imitate ideas and concepts from nature to resolve technological problems. Solutions coming from plants have the potential to face challenges and difficulties of modern engineering design. Characteristic concepts of the plant world such as reiteration, modularity and swarm behaviour could be of great help resolving technological problems...

This paper describes a non-invasive remote temperature measurement technique integrated with a biomechatronic surgery system devised in our laboratory and named FUSBOT (Focal Ultrasound Surgery RoBOT). FUSBOTs use High-Intensity Focused Ultrasound (HIFU) for ablation of cancers/tumors and targets accessible through various soft-tissue acoustic windows in the human body. The focused ultrasound beam parameters are chosen so that biologically significant temperature rises are achieved only within the focal volume...

It has been concluded from numerous neurophysiological studies that humans rely on detecting discrete mechanical events that occur when grasping, lifting and replacing an object, i.e., during a prototypical manipulation task. Such events represent transitions between phases of the evolving manipulation task such as object contact, lift-off, etc., and appear to provide critical information required for the sequential control of the task as well as for corrections and parameterization of the task. We have sensorized a biomechatronic anthropomorphic hand with the goal to detect such mechanical transients...

This paper presents a biomechanical model of the semicircular canals of the human vestibular system and the design of a 3D biomimetic structure that mimics the biological system. Starting from anatomical and physiological data, mechanical and structural parameters have been identified and a mathematical model has been formulated, by considering the semicircular organ as a canal filled by a liquid. The mathematical and mechanical models were used to simulate the behavior of the semicircular canals under known conditions of angular velocity and acceleration along three axes...

The neurorehabilitation robotics is a promising research field that allows improvements of the therapy effects. Some interesting systems for the neurorehabilitation of the upper limb are based on standard robotic arms and their applicability and effectiveness are based on the presence of patient's residual motor control synergy. On the other side, the exoskeletons overcome the single joint control allowing the full control of the arm kinematics. This paper presents the first results obtained at ARTS lab for the development of an exoskeleton for upper limb, starting from one of its building block that is a stand-alone active orthesis for functional assessment of the human wrist...

This paper presents the design methods followed in order to overcome the limits of the current prosthetic hands. The prosthesis biomechatronic approach arises from the knowledge of the biological system, assumed validated by its natural evolution. Nevertheless, the state of the art of technology, actuators, sensors, electronics and software, forces some trade-off in the implementation of the prototypes. The current hand prototype constitutes the platform used to direct all efforts of the prosthesis designer to the final goal: the cybernetic hand directly connected to the nervous system...
