Using a novel broadband microchamber, electrical detection of live and dead single cells was demonstrated. Tests on Jurkat cells showed that live cells had lower resistance but higher capacitance than that of dead cells. The test results were compared with the limited literature on broadband electrical detection of single cells and the discrepancies, both qualitative and quantitative, were discussed. These results indicate that, while broadband electrical detection at the single-cell level is becoming feasible, many challenges remain in impedance match, calibration, sensitivity, cell manipulation, solution effect and modeling.

A numerical assessment methodology to understand the EMI imposed by magnetic resonance type wireless power transfer systems on active implantable medical devices (implantable cardiac pacemaker/cardioverter defibrillator) is introduced. A numerical estimation model that consists of magnetic resonant coils and a human torso phantom with a pacemaker model is constructed. Numerical simulation based on the finite element method yields the interference voltage induced at the connector of the pacemaker inside the torso phantom. Our example assumes magnetic resonance coils operating in the frequency band of 10 MHz.

This paper presents a stub-loaded printed antenna with a full ground plane and electromagnetically coupled feed for body area network devices operating in industrial, scientific, and medical (ISM) band at 2.45 GHz. Performance and characteristics are presented along with parametric analyses. Antenna performance is investigated under bending to check its suitability for conformal body centric wireless communication devices. The electromagnetically-coupled feed is tuned to fill a null in the radiation pattern and to achieve impedance matching, which is further fine tuned by stub loading. The proposed antenna exhibits a wide radiation pattern along the body surface to provide maximum coverage and its narrow physical width (14mm) makes it suitable for on-body applications.

With the growth of the demand of smaller and smaller implantable devices, THz technologies becomes appealing for potential applications in Body Area Networks at nano-scale. As an essential part for understanding the in-body propagation at THz frequency numerical investigations are presented in this paper to simulate the absorption path loss of fat at THz frequency. The results of the proposed analysis suggest that a distance in the order of millimeter might be suitable to guarantee a communication link between nano-devices located in human tissues.

Many biomedical applications, including in-body localization, in vivo sensor data acquisition, and measurement of the electrical properties of human tissues require or may greatly benefit from a highly concentrated and directional beam emanating from a transmitting antenna. While many beam focusing efforts have utilized large aperture antennas or large antenna arrays, these methods are not always convenient for biomedical use. Furthermore, sensing modalities operating in the far-field susceptive to multi-path issues related to the many diverse material property interfaces within the human body. This work presents the theoretical background related to the construction and operation of a very small and easily located antenna that generates a highly directive signal ideal for biomedical use. The antenna, constructed from a pair of orthogonally oriented magnetic dipoles excited in quadrature, utilizes the advantages associated with operating in the Fresnel region, directing most of its emitted energy 45 degrees from broadside. Numerical simulations support this operation and have led to a number of applications as identified herein prompting the development of a Finite Element Method compatible human body model based on the Visible Human Project data maintained by the National Institute of Health.

Wireless implantable devices have revolutionized the field of biomedical engineering for as long as adequate power supplies are conjured. This paper presents an ultrasonic power link front-end interfaced with a capacitive micromachined ultrasonic transducer (CMUT). The ultrasonic power link front-end consists of a rectifier, a charge pump, a clock extractor and a phase generator. The power link front-end designed in 0.18-μm CMOS process provides a 17 V DC supply for the implant microsystem, e.g. neural stimulator. It achieves an overall power efficiency of 0.3% in simulation.

Energy distribution under the human skin during ultrasound power transfer using a 15×15 MEMS transducer array with 2.2 MHz driving frequency is presented in this paper. When the surface pressure of the array element is 96 kPa, intensity at 2 mm under the skin is 0.96 W/cm2; intensity increases to 24 W/cm2 when the surface pressure increases to 0.48 MPa. In other words, the simulation results show that the larger the surface pressure, the larger the intensity. The simulated and the measured power density values at 7 mm in the vertical direction of the transducer surface in degassed water are 96.72 mW/cm2 and 94.08 mW/cm2, respectively. Temperature change due to ultrasound radiation on the skin is discussed, and the feasibility of ultrasonic power transfer for implantable medical devices specially implanted just underneath the skin is presented.
