This study presents an approach to use different biomedical signals in order to do biometric identification. The biomedical signals are captured using Arduino and Libelium platforms, what offers a low cost solution. The biomedical signals used are Electromyogram, Electrocardiogram and the Galvanic Skin Response. These signals are parametrized using well-known measures and Neural Networks are used...
In this letter, a preliminary study of the progression of bone healing in hip fracture model is done using a non-invasive Split Ring Resonator sensor (SRR). An SRR sensor was designed and used on phantom models representing different locations of femur such as distal, thigh and trochanter. For use on these targets and to model the bone healing different morphologies of tissues are considered and their...
Different from traditional multiple backbones continuum manipulators, a novel elephant-trunk manipulator, called ET Arm, is design and developed. The ET Arm is composed of one or two segments (called muscle segment). The muscle segment includes three reduced motors, three flexional rods connected to screw, multiple disks, springs and wired bellows. When any flexional rod and the screw at the end of...
This paper describes a flexible loop antenna for in-body applications. This antenna works in the Med Radio band(402 MHZ–406 MHZ) which is the standard band for Bio Implantable applications, ISM Bands at 433 MHZ“434.8 MHZ and 902 MHZ“ 928 MHZ. The antenna is having a size of a 3.5 mm radius and height of 15 mm. The simulated antenna is having a Bandwidth of 228 MHZ (310 MHZ–538 MHZ) at 400 MHZ and...
Essential tremor (ET) is one of the most common movement disorders that causes a rhythmic trembling of the hands, head, voice, legs or trunk. Currently, no medication is specifically designed to treat ET, However, some solutions exist to temporarily suppress tremor. This paper presents a novel low cost alternative to the existing solutions, known as Functional Electrical Stimulation (FES) and its...
The purpose of this study was to estimate the effects of some anatomical, physiological and detection system parameters on the root mean square (RMS) and the total power (TTP) of simulated surface electromyographic (EMG) signals generated in a cylindrical multilayer volume conductor represents the limb muscle. These signals were detected by the longitudinal single differential (LSD), transversal double...
A good comprehensive study of the electromagnetic properties of biological layers is important since we cannot discuss an implantable antenna design without investigating the interaction of electromagnetic radiation with the tissue. The human body is not an ideal medium for the transmission of radio waves which can be considered as a barrier degrading the performance of the transmission system that...
This paper proposes a novel wireless link for energizing pulse generators for deep brain stimulation. The proposed link consists of two magnetically coupled planar resonators. Experimental results referring to a prototype working in the MedRadio band and using minced pork in order to take into account the presence of human tissues are reported and discussed. Results obtained this way demonstrate a...
Wireless power delivery and telemetry are the key aspects of an implantable device that enables long-term operation which is otherwise limited by the factors like battery capacity (in battery operated systems), infections and pain (tethered systems). In this paper, we present our efficient wireless power delivery and reliable telemetry platform that enables a completely implantable muscle stimulator...
A wearable RFID reader antenna operating in the UHF band is considered for its application in the scenario of tracking humans in a controlled environment as a navy ship.

The recent surge of implantable and wearable medical devices have paved the way for realizing intra-body networks (IBNs). Traditional RF-based techniques fall short in wirelessly connecting such devices owing to absorption within body tissues. A different approach is known as galvanic coupling, which employs weak electrical current within naturally conducting tissues to enable intra-body communication...

The most detailed models we have used have contained approximately 35000 vertices and 70000 polygons. We have...
Surface electromyography (SEMG) systems are able to effectively sense muscle activity, irrespective of any apparent body motion, in a highly convenient and non-intrusive manner. These advantages make SEMG based systems highly attractive for use as a human computer interface. Despite such advantages, there are still a significant amount of challenges that should be resolved before such systems can...
