“…Most research groups have used active sensors that consisted of a reusable preamplifier circuit located as close as possible to the CRE (usually on the back of the sensing electrode), and then transmit the captured signal by cable to an external bioamplifier for further analogue processing [3,[5][6][7]11]. In this context, the trend in ECG monitoring is towards minimizing wiring and developing smart wearable or wireless systems that provide greater patient comfort and simplify the recording system and protocol [2,[12][13][14].…”

Concentric ring electrodes (CRE) have been proposed for sensing bioelectrical activity with high spatial resolution. Computational studies have revealed that the CRE dimensions are closely related to the electric dipole depth they can sense, but further experimental confirmation is needed. We aimed to develop and test a wireless multichannel ECG recording system based on a new flexible multi-ring electrode and to check the influence of CRE dimensions on the acquired signals. The system provided high-precision ECG signals by a simple procedure. The bipolar concentric ECG signal amplitude and SNR increase with the CRE's outer ring dimension. Differences in the signal morphologies, associated with different sensitivities to the location of the active dipoles, were also obtained in the case of diameters smaller than 34mm. A system with several wireless sensor nodes developed could be easily used by clinical staff for non-invasive cardiac monitoring and diagnosis with high spatial and temporal resolution.

“…The Receiver module is interfaced with the Laptop through the sound port and wireless EMG signal can again be seen on the virtual oscilloscope. The arrangement also helps in acquiring wireless ECG signals [20]. However, changes in the band pass frequency range needs to be made in the algorithm to acquire the EMG signal.…”

The paper represents work on the challenge of real time, non-invasive simultaneous acquisition and wireless transmission of human physiological parameters using easy and cost effective approach. Electromyograph (EMG) signal detection and analysis is utilized in various clinical and biomedical applications including generation of control signal for prosthetic tools. However, better solutions to obtain noise free signal using compact detection arrangement and wireless communication technologies are being upgraded. In this work, surface EMG signal is acquired under various levels of bicep muscle contractions using simple computer interface and processed using MATLAB based Filter algorithm for online clean display and wireless transmission. EMG and Carotid artery pulsation are then acquired in time coherence to analyse the effect of rectus abdominis muscle contractions on carotid pulse wave and developed into a stand alone MATLAB executable file. The effect manifests as raised amplitude in the Carotid pulse wave form. Hence, a clear correlation is established between surface EMG signal and Carotid artery pulsation to give a compact, cost efficient solution to physiological signal monitoring.

“…Probably the most popular medical signal to be implemented in telemedicine kits is the ECG signal. The prototypes developed in [1] and [2] and [3] aim to perform a real time ECG measurement with wireless transmission. The authors in [1] used an amplification stage based on op amps prior to the transmission.…”

Telemedicine is always a popular topic thanks to the constants advancements of technology. The focus on development of new devices has been mainly on decreasing size to increase portability. Our research focused on improving functionality but not giving up on portability and cost. In this paper we are presenting the first prototype device that measures 4-leads electrocardiogram (ECG) and phonocardiogram (PCG) signals with low cost, high portability and wireless connectivity features in mind. We designed and developed a prototype that measures ECG using a standard ECG cable; we designed and developed a digital stethoscope prototype and also the necessary hardware for both medical signals to be transmitted through Bluetooth to a computer. We present here the hardware design, a new communication protocol for transmission of both signals from the device to the computer, and the software system to enable remote consultations. We designed the prototype with the main purpose of using low cost parts without sacrificing functionality, with the purpose of using it in remote zones of the Caribbean coast of Colombia. We show open issues and prepare a field implementation of the kit in the target zone.
