摘要

开发无线生物识别传感器的主要挑战之一是需要将各种系统集成到一个非常紧凑的设备中。这些系统包括传感单元、调节电子设备、变送器和电源。本文提出了一种新的系统集成体系结构。这种新架构的一个独特之处在于，子系统被选择和设计为直接输出到输入连接。一组有源pH传感器用于将pH值转换为0 - 2伏范围内的电位。该信号由适合人体运动操作的静电能量采集器放大。放大的信号驱动一个定制的LC变送器，专门设计以适应收割机的输出。实现了一个非常简单的系统，并可作为其他无线传感器的演示。

MEMS Energy Harvesting Powered Wireless Biometric Sensor

One of the main challenges in developing wireless biometric sensors is the requirement for integration of various systems into a very compact device. Such systems include sensing units, conditioning electronics, transmitters and power supplies. In this work, a novel system integration architecture is presented. A unique feature of this new architecture is that the sub-systems are selected and designed for direct output-to-input connection. An array of active pH sensors is used to transform a pH level to an electrical potential in the range of 0 - 2 Volts. This signal is amplified by an electrostatic energy harvester suitable for human motion operation. The amplified signal drives a custom LC transmitter specially designed to suit the harvester output. A system of notable simplicity is achieved and may serve as a demonstrator for other wireless sensors.
