A wireless bio-medicalr sensor Network was designed to detect a human heartbeat and respiration signals without direct skin contact. In order to design a wireless bio-medical sensor quantitatively, the signal to-noise ratio (SNR) in the baseband output of a sensor should be calculated. Therefore, we analyzed the SNR of the wireless biomedical sensor, considering the signal power attenuation in ...

The development of a bio-hybrid tactile sensor array that incorporates a skin analogue comprised of alginate encapsulated fibroblasts is described. The electrical properties are modulated by mechanical stress induced during contact, and changes are detected by a ten-channel dual-electrode impedance sensing array. By continuously monitoring the impedance of the sensor array at a fixed frequency,...

Plankton research has always been an important area of biology. Due to various environmental issues and other research interests, plankton hatching and harnessing has been extremely red-marked zone for bio-aqua scientists recently. To counter this problem, no wireless sensor assisted technique or mechanism has yet not been devised. In this literature, we propose a novel approach to pursue this ...

BACKGROUND There have been many studies that utilize the bio-impedance measurement method to analyze the movements of the upper and lower limbs. A fixed electrical current flows into the limbs through four standard disposable electrodes in this method. The current flows in the muscles and blood vessels, which have relatively low resistivity levels in the human body. This method is used to measu...

In this paper, we are focused on a mobile human emotion recognition system which is based on biosignal. Cardio signal is a proper bio-signal for emotion recognition and we use photoplethysmography (PPG) sensors to gather cardio signals. We mainly consider real-time heart rate variability (HRV) analysis which is essential to mobile emotion recognition. A mobile sensor module embedding a digital ...

Advanced remote sensing techniques and algorithms are combined to produce and analyse an improved 12-year multi-sensor time series of bio-optical properties for the Adriatic Sea. First, a multi-sensor series of normalized water-leaving radiance is created with an optically-based merging technique applied to SeaWiFS and MODIS data. Then, two empirical algorithms, embedded in a dynamic algorithm ...

Nowadays sensors and especially biosensors play an important role in medical diagnosis and detection of food and environment contaminations. Biosensors’ facilities have been improved significantly by using technologies such as surface plasmon resonance, microfluidics, laser, and electrochemistry. These technologies are now available on chips in micro- and nano-scale and are capable of mea...

Clustered sensor networks have shown to increase system throughput, decrease system delay and save energy. In this paper, we propose a bioinspired clustering protocol inheriting the social behavior of Rhesus Macaque monkeys, targeting prolonged network lifetime. The behavioral features are added to the basic LEACH, thereby reducing the energy overhead involved in the set-up phase. The simulatio...
