项目摘要

DESCRIPTION (provided by applicant): A clear need exists for the development of advanced power sources and recharging protocols for implanted electro-medical devices. The useful lifetime of most implants is constrained by the longevity of the power source. Pacemaker and other implantable battery replacement procedures are expensive, cause patient distress, and have the potential for causing infections. Many new and emerging medical device technologies, such as enhanced inter-device telemetry, automated wireless alarm signaling, advanced sensors, and infusion pump therapies, continue to place demands on power. A novel new method for recharging secondary batteries can provide significant advantages over the infrequently used currently method. A wireless power transmission method based on the principle of ultrasound technology is being developed. The concept is made feasible by the development of PMN-PT, an advanced material that exhibits significant potential for transforming acoustic to electrical power. The potential advantages include much smaller transmitters and receivers, receivers that can be embedded in devices, and elimination of electromagnetic interference and metal heating. The goal is to demonstrate the feasibility of significant wireless power transfer to sites within the body using this material. Specific aims include designing the receiver, making the material with the correct properties, fabricating the receiver, developing the circuitry to mate it to the implantable battery, confirming useful power transmission levels experimentally, meanwhile being careful to adhere to accepted FDA ultrasound safety guidelines.

描述（由申请人提供）：明确需要为植入式电子医疗器械开发先进的电源和充电方案。大多数植入物的使用寿命受到电源寿命的限制。起搏器和其他植入式电池更换程序昂贵，导致患者痛苦，并有可能导致感染。许多新的和新兴的医疗设备技术，如增强的设备间遥测、自动无线报警信号、先进的传感器和输液泵治疗，继续对电力提出要求。一种用于对二次电池再充电的新颖的新方法可以提供优于目前不经常使用的方法的显著优点。正在开发基于超声波技术原理的无线电力传输方法。PMN-PT是一种先进的材料，具有将声学转化为电力的巨大潜力。潜在的优势包括更小的发射器和接收器，可以嵌入设备中的接收器，以及消除电磁干扰和金属加热。目标是证明使用这种材料将大量无线功率传输到体内部位的可行性。具体目标包括设计接收器，使材料具有正确的属性，制造接收器，开发电路将其与植入式电池配对，通过实验确认有用的功率传输水平，同时注意遵守公认的FDA超声安全指南。
