Since the introduction of implantable pacemakers in the early 1960s, implantable medical devices have become more and more interesting for healthcare services. Nowadays, the devices designed to monitor physiological data from inside the human body have gre ...

This work presents the design and realization procedure of small implantable antenna for biotelemetry applications. The radiator occupies a volume smaller than 3 cm(3) (without its biocompatible insulation), is well matched within the Medical Implanted Com ...

Nowadays mobile and battery-powered applications push the need for radically miniaturized and low-power frequency standards that surpass the stability achievable with quartz oscillators. For the miniaturization of double-resonance rubidium (Rb-87) atomic c ...

We present our studies on a compact high-performance continuous wave (CW) double-resonance (DR) rubidium frequency standard in view of future portable applications. Our clock exhibits a short-term stability of 1.4 x 10(-13) tau(-1/2), consistent with the s ...

This paper presents a method for the analysis of planar multilayered waveguide-fed antennas. The method combines mixed-potential integral equations (for laterally open regions) and modal field integral equations (for laterally closed regions) with a seamle ...

Nowadays there is an increasing need for radically miniaturized and low-power atomic frequency standards, for use in mobile and battery-powered applications. For the miniaturization of double-resonance (DR) Rubidium (Rb-87) atomic clocks, the size reductio ...

The design procedure, realization and measurements of an implantable radiator for telemetry applications are presented. First, free space analysis allows the choice of the antenna typology with reduced computation time. Subsequently the antenna, inserted i ...

A wireless sensor platform for use in ultralow-power wireless sensor networks (WSNs) is presented. The proposed round sensor (RoSe) node is physically robust, is resistant to humidity, and has a housing that can be in direct contact with food. These charac ...

This work investigates the measurement of electrically small implantable antennas. Several radiators have been analyzed showing the importance of the feeding coaxial cable that is usually used for testing purposes. Simple solution to the problem is present ...

In this paper a new wireless sensor node intended for use in ultra-low power Wireless Sensor Networks (WSN) is presented. The node uses commercial of-the-shelf radio, microcontroller and a custom developed antenna embedded in the housing. Over-molding with ...
