“…8 shows that the proposed ASK demodulator can even recover the modulated signal correctly when the data rate is up to 1.2 Mb/s. For wireless communication used in biomedical applications, the maximum data rate is about 240 kb/s [15]. Therefore, the proposed circuit has met the demands of many biomedical applications.…”

An all-MOS ASK demodulator with a wide bandwidth for lower industrial, scientific and medical (ISM) band applications is presented. The chip area is reduced without using any passive element. It is very compact to be integrated in a system-on-chip for wireless biomedical applications, particularly in biomedical implants. Because of low area cost and low power consumption, the proposed design is also easy to integrate in other mobile medical devices. The self-sampled loop with a MOS equivalent capacitor compensation mechanism enlarges the bandwidth, which is more than enough to be adopted in any application using lower ISM bands.Index Terms-Amplitude shift keying (ASK) demodulator, industrial, scientific and medical (ISM) band, self-sampled, wireless communication.

“…To preserve quality of service (QoS), techniques including adaptive channel coding, dynamic power adjustment, MIMO, and QoS-aware MAC should be used. UWB is also widely considered in [66] and [23]. The use of newer technologies involves: Smart textiles [42] that embed sensing and wireless capabilities in clothing, energy-aware routing protocols [36], near-field communications [2] that suffer path loss less than the more traditional radiated communications, and body-coupled communications (BCC) [3] that use the human body as transmission channel at frequencies below 100MHz, thus eliminating complex modulation schemes and high-frequency front-ends.…”

We provide a comprehensive review of the challenges and emerging technologies for WBANs: Wireless Body Area Networks. We describe leading applications and the tiers of the WBAN architectures, itemizing their major design areas. A succinct review of solutions, progress and possible future research in the areas of sensors, power and radio hardware components, the network stack, localization and mobility techniques, security and privacy, and of certification and standardization follows. We finally make the connection between WBANs and the fast growing research field of Cognitive Radios, which help establish efficient wireless transmissions in an increasingly crowded radio spectrum.

“…The theoretical formulation for the imaging procedure was presented and regions of filtration were distinguishable from regions where the ultrafiltrate was concentrated. Combined sensing and communication using FM-UWB waveforms operating at 4.5±0.5 GHz were able to non-invasively monitor heart rate and transmit the data for over wireless channels [62].…”

Medical radar is an emerging area of research and development in recent years, spurred by rapid advances in electromagnetic modeling, simulation, component development, and signal and image processing algorithms. In this paper, we review various important considerations in the design and development of medical radar systems for diagnostic applications.Most medical radar applications basically need two components: a sensor and a communication infrastructure (transceiver and protocols) to share the data gathered by the former [7]. By combining sensing and communications in the same package, UWB radar could be used to measure vital signs information, and UWB communication standards could be used to transmit these measurements to a processor. Wireless networking is necessary to transmit and share the monitored data with a central repository.It is important to ascertain which phenomenon actually impacts measured data. It was shown that body surface movements dominated remote radar measurements of heartbeat, compared to blood perfusion in the skin or internal body organ movements [8].A comprehensive list of relevant literature on medical radar is presented in [9], which includes references on general UWB radar, radar calibration, radar heartbeat and respiration measurements, medical radar systems, and medical radar imaging. DIELECTRIC PROPERTIES OF TISSUEThe dielectric properties of human tissue determine the radar reflections from different layers. Relevant data are available from several papers and reports over the past 60 years.Some of the earliest permittivity and loss measurements of various human tissues, such as skin, fat, muscle, etc. were made at centimeter wavelengths, over the 1-26 GHz frequency range [10]-
