Recent advances in microelectronics and integrated circuits, system-on-chip design, wireless communication and intelligent low-power sensors have allowed the realization of a Wireless Body Area Network (WBAN). A WBAN is a collection of low-power, miniaturized, invasive/non-invasive lightweight wireless sensor nodes that monitor the human body functions and(More)
Recent advances in Micro-Electro-Mechanical Systems (MEMS) technology, integrated circuits, and wireless communication have allowed the realization of Wireless Body Area Networks (WBANs). WBANs promise unobtrusive ambulatory health monitoring for a long period of time and provide real-time updates of the patient’s status to the physician. They are widely(More)
In both the warm pool region and the high-nutrient low-chlorophyll (HNLC) region of the equatorial Pacific, the phytoplankton community is dominated by high concentrations of picophytoplankton regardless of whether El Ni * no, La Ni * na or normal conditions prevail. Flow cytometry measurements indicate that the picoplankton community consists of two(More)
Mohs micrographic surgery (MMS) has increasingly become an accepted therapy for melanoma in situ on chronically sun damaged skin (CSDS). However, melanocytes are difficult to locate in frozen material on hematoxylin and eosin. In addition, determining the cut-off between the melanoma and the "atypical melanocytic hyperplasia" in CSDS can be challenging in(More)
This paper presents an empirical investigation on the performance of body implant communication using radio frequency (RF) technology. In body implant communication, the electrical properties of the body influence the signal propagation in several ways. We use a Perspex body model (30 cm diameter, 80 cm height and 0.5 cm thickness) filled with a liquid that(More)
Healthy Aims is a 23- million, four-year project, funded under the EU's information society technology sixth framework program to develop intelligent medical implants and diagnostic systems (www.healthyaims.org). The project has 25 partners from 10 countries, including commercial, clinical, and research groups. This consortium represents a combination of(More)
A Body Senor Network (BSN) allows the integration of miniaturized, intelligent, low power, invasive, and non-invasive wireless sensor nodes to monitor body function and the surrounding environment. The inclusion of wireless sensor nodes within the body requires many more constraints to be met for safe and reliable operations. In this paper, we first study(More)
Recent advances in intelligent sensors, microelectronics and integrated circuit, system-on-chip design and low power wireless communication introduced the development of miniaturised and autonomous sensor nodes. These tiny sensor nodes can be deployed to develop a proactive Body Sensor Network (BSN). The rapid advancement in ultra low-power RF (radio(More)
This paper shows how Radio Frequency (RF) communication is possible for implanted medical devices. RF links between implanted medical devices and external monitoring and programming equipment is becoming more common. However, as new RF applications are introduced the battery operating life of the implanted medical device is a concern. This paper describes a(More)
