Feasibility Study for Non-Contact Heartbeat Detection at 2.4 GHz and 60 GHz
نویسندگان
چکیده
Two new schemes for human non-invasive cardiopulmonary activity monitoring are demonstrated using microwave low power and non-contact Doppler sensors. The two systems, using direct conversion architecture and simple design, are demonstrated and tested at a distance of 1 m from the patient. The first one proposes a simple technique for direct measurement of heartbeat signal at 2.4 GHz while the second scheme improves detection sensitivity when operating at 60 GHz.

Klebsiella pneumonia, a Microorganism that Approves the Non-linear Responses to Antibiotics and Window Theory after Exposure to Wi-Fi 2.4 GHz Electromagnetic Radiofrequency Radiation
Background: Drug resistance is widely believed to be an increasingly serious threat to global public health. We have previously reported that short term exposure of microorganisms to diagnostic ultrasound waves could significantly alter their sensitivity to antibiotics. In our previous studies, Klebsiella pneumoniae showed major differences in the sensitivity to antibiotics in exposed and non-e...

Background: Electromagnetic fields (EMF) with different intensities are widely used at home, offices and public places.Today, there is a growing global concern about the effects of human exposure to EMFs. Epilepsy is one of the most common chronic neurological diseases, affecting 50 million people of all ages worldwide. We aimed to investigate the effect of exposure to Wi-Fi radiation on epilep...
متن کاملMicrowave Doppler Radar for Heart Beat Detection Versus Electrocardiogram: A Validation Approach
This paper provides a validation approach for a microwave Doppler Radar system used for heartbeat detection. The proposed system is tested at 16 GHz with several transmitted power, simultaneously with a pc-based electrocardiogram. Obtained results show accurate detection for the heartbeat signal in terms of heartbeat rate and heart rate variability.

In this paper, the design, implementation, and experimental results of a high-efciency dual-band GaN-HEMT Doherty power amplier (DPA) are presented. An extensive discussion about the design of the passive structures is presented showing different possible topologies of the dual-band DPA. One of the proposed topologies is used to design a dual-band DPA in hybrid technology for the frequency ba...
