In Vivo Demonstration of Addressable Microstimulators Powered by Rectification of Epidermically Applied Currents for Miniaturized Neuroprostheses
Electrical stimulation is used in order to restore nerve mediated functions in patients with neurological disorders, but its applicability is constrained by the invasiveness of the systems required to perform it. As an alternative to implantable systems consisting of central stimulation units wired to the stimulation electrodes, networks of wireless microstimulators have been devised for fine m...
متن کاملReal-time sonography to estimate muscle thickness: comparison with MRI and CT.
PURPOSE We investigated the feasibility of using real-time sonography to measure muscle thickness. Clinically, this technique would be used to measure the thickness of human muscles in which intramuscular microstimulators have been implanted to treat or prevent disuse atrophy. METHODS Porcine muscles were implanted with microstimulators and imaged with sonography, MRI, and CT to assess image ...
متن کاملWireless Microstimulators Based on Electronic Rectification of Epidermically Applied Currents : Safety and Portability Analysis
Miniaturization of implantable medical electronic devices is currently compromised by the available means for electrically powering them. Most common energy supply techniques for implants – batteries and inductive couplers – comprise bulky parts which, in most cases, are significantly larger than the circuitry they feed. For overcoming such miniaturization bottleneck in the case of implants for...
متن کاملBladder-wall and pelvic-plexus stimulation with model microstimulators: Preliminary observations.
Severe urinary retention is not a common condition, but may occur following some pelvic surgeries or other medical conditions. Electrical stimulation of the bladder has been examined as a means of managing this difficult problem. We conducted preliminary investigations in cats to prove the hypothesis that pelvic-plexus (bladder-neck) stimulation would produce greater micturition response with r...
متن کاملLow Power Wireless ECG Acquisition and Cardiac Stimulation SOCs for Body Sensor Networks
In recent years, body sensor networks (BSNs) based applications or devices have become more and more popular, and acceptable to the people for monitoring the real-time health information, such as the electrocardiogram (ECG). In order to enhance the portability and increase the popularization of BSNs, a low-power wireless ECG acquisition system on a chip (SOC) stuck on the body is required. In t...
