In near-field electromagnetic links, the inductive voltage is usually much larger than the compliance of low-voltage integrated-circuit (IC) technologies used for the implementation of implantable devices. Thus most integrated power-recovery approaches limit the induced signal to low voltages with inefficient shunt regulation or voltage clipping. In this paper, we propose using high-voltage (HV) complementary...
Implantable biomedical devices such as sensors and neurostimulators require a near-field inductive link to transmit power wirelessly. However, the near-field induced voltage is usually much larger than the compliance of low-voltage integrated circuit technologies. Thus most integrated power recovery approaches limit the induced signal to low-voltages with inefficient shunt regulation, or voltage clipping...
For most implantable biomedical devices, inductive power is an important alternative to the limited lifetime batteries. In case of a near-field inductive link, the induced voltage is usually much larger than the compliance of low-voltage integrated circuit (IC) technologies. Most power recovery approaches limit the voltage with inefficient shunt regulation, or voltage clipping. In this paper, a step-down...
Wirelessly powered implantable biomedical devices require a near-field inductive link to provide enough power for high current stimulation of large electrode-nerve impedances. In that situation, the induced voltage may be much larger than the compliance of low-voltage integrated circuits, especially during low-load conditions. In fact, most power recovery approaches limit the voltage with an inefficient...
The electrode-tissues interface (ETI) is one of the key issues for the safety, reliability and efficiency of implantable devices such as stimulators and sensors. The aim of this paper is to report an implantable telemetry device, based on a full custom integrated circuit (IC) to monitor the ETI. The proposed system performs various types of measurements, such as impedance spectroscopy, cyclic voltammetry,...
This paper concerns the design and implementation of a Bi-channel Selective Neurostimulator (BSN). It is dedicated to demonstrate the efficiency of bilateral sacral roots stimulation during chronic experiments in small animals (rats). The complete BSN implant has been highly miniaturized. It is powered and controlled by an inductive RF link and includes two channels. Even though they are meant for...
This paper concerns the design and implementation of a new implantable Neuro-Monito-Stimulation System (NMSS) for the urinary tract rehabilitation in paraplegics. In addition to selective stimulation for voluntary micturition and permanent stimulation for reduction of the detrusor overactivity, the NMSS includes telemetry capabilities of electrodes-tissues contact. Resistance up to 10 kOmega could...
