Thermal Energy Based Resonant Inductively Coupled Wireless Energization Method for Implantable Biomedical Sensor

Abstract

Abstract-In order to energize the biomedical implantable electronic devices wirelessly for in vivo health monitoring of patients in remote and inaccessible areas, an alternate driving energy source is highly desirable and increasingly important. In pertinent to this, a thermal energy driven resonant inductively coupled wireless energizing scheme has been developed for powering biomedical implantable devices. The system is designed to convert the generated heat energy to a high frequency energy source so as to facilitate energy transfer through resonant inductive link to the automated biomedical sensing system allied with the receiver unit. The automated biomedical smart sensor is competent to acquire the body parameter and transmit the consequent telemetry data from the body to the data recording segment. The real-time body temperature parameter in different conditions has been experimented. To ensure its accuracy, the sensed data have been matched with the observations carried out by a calibrated device. The intended scheme can be utilized for wireless monitoring of other health parameters like physiological signals and bladder as well as blood pressure of the patients.

Photovoltaic Driven Resonant Wireless Energy Transfer System for Implantable Electronic Sensor

“…This necessitates the pursuit of wireless energizing technique which is cordless, reliable, safer, smarter, and environmental friendly [9,10]. Although the inductive coupling based wireless energization technique is acceptable for powering the sensors, but not widely adopted because of its coil configuration, large dimension and low efficiency [11], providentially, the magnetic resonant coupling based wireless technique goes to the forefront recently and also has been regarded as a viable method for powering electronic devices [12][13][14][15][16]. However, to expand the usability of the wirelessly energized implantable electronic devices for continuous patient monitoring in inaccessible and outdoor areas derelict of grid power supply, renewable energy based energizing system can be a partial and accepted solution [17].…”
