A System for Wireless Power Transfer and Data Communication of Long-Term Bio-Monitoring

Abstract

Abstract-

Ultra-Reliable Cooperative Short-Packet Communications With Wireless Energy Transfer

“…Substituting (7) into (15) and using the PDF expression for g SD and g DS , we attain (16) and (17). Notice that for the infinite battery case, (7) becomes γ = φg SD g DS − ϕg SD .…”

Miniature implantable telemetry system for pressure-volume cardiac monitoring

“…Here, both a custom pressure sensor and telemetry system were developed, however, it was designed to monitor femoral pressures and not the higher LV pressure. Others [127,137] have focused on creating wireless power systems for these pressure implants to be used long term. Full implantable blood vessel cuff monitoring systems have also advanced throughout the years to current state-of-the-art methods such as the systems mentioned in [79] and [220].…”

“…These batteries are typically replaced via a surgical procedure that can cause complications with patients. Research into different battery technologies has yielded smaller, higher density batteries, however, these are still only available in research applications [126][127][128][129]. Higher power applications including pacemakers, neurostimulators, etc, will often utilize rechargeable batteries to extend the life of the implant.…”

“…This is significantly important for small animal implant design as the size is severely limited, thus the applicable power sources are limited [4]. Nevertheless, small animal power transfer is an active area of research focusing on coil misalignment [136] and full power cage solutions [21,126,127,[144][145][146].…”

Skin-Integrated Wearable Systems and Implantable Biosensors: A Comprehensive Review

“…Asgari et al integrated an antenna, a transceiver unit and a wireless network algorithm to enable their left ventricular assistance devices to establish a reliable telemetry communication with an extracorporeal platform, such as a smartphone, tablet or personal computer [123]. Kilinc et al presented a system for wireless power transfer and data communication of battery less biosensor systems implantable in small animals, based on an implant coil placed to induce AC voltage from the available magnetic field [124]. Ryou et al developed an endoscopically implantable biosensor for real time detection of UGIB equipped with a radio and antenna capable of transmitting out of the body and wirelessly linked to an external computer and transceiver [125].…”
