Wireless telemetry system for implantable cardiac monitoring in small animal subjects using pressure-volume sensors

Miniature implantable telemetry system for pressure-volume cardiac monitoring

“…Physical implementation of the telemetry system is described in Section 4.6. * Portions of this chapter are published in NEWCAS 2013 [239], BIOCAS 2013 [31], and published in Springer Biomedical Devices Journal [240]. The external unit consists of a wireless transceiver, microcontroller, and computer for processing.…”

“…In this section, the design and experimental details of a custom 3D bio-compatible implantable capsule that is used to house the wireless telemetry system designed in Chapter 4 is presented [30,31]. The capsule is designed specifically for the dimensions and shape of the PV system and is 3D printed in four different materials: ABS, RDG720 Transparent Acrylic, ABS-M30i, and 316L Stainless Steel.…”

An 11‐μ W, 9‐bit fully differential, cyclic/algorithmic ADC in 0.13 μm CMOS

“…For example, the ADC can be used in implantable bio‐telemetry systems or other bio‐medical devices. One such system is presented by Fricke in and . His system is designed for cardiac monitoring in small animal subjects with peak heart rates of ∼ 180 bpm (3 Hz) or a highest Nyquist tone of 200 Hz.…”

CMOS voltage regulator for RF energy harvester

“…Motivations to achieve this particular objective are multiple; creating a telemetry system of such complexity and micro size is exceptionally challenging engineering and academic task [1]. What is more, constraints imposed on practical solutions for energy harvesting, low power consumption, and the integration of implantable systems require some new theoretical and/or technological advances.…”
