AEI(Applicable Electronics Inc.)公司由Alan Shipley成立于1984年。AEI公司与Science Wares公司合作，设计开发由电脑控制的、快速的、非损伤的扫描微电极测量系统，用以检测传导介质溶液中的离子流。
AEI公司主要负责设计和制造硬件系统，包括计算机控制运动定位系统、各种信号放大器、视频缩放系统及各种机械装置和配件。

一、非损伤的扫描微电极测量系统:

SIET/SPET
SIET（扫描离子选择性电极技术）可以在皮摩尔量级测量离子浓度变化。SPET(扫描式极谱电极技术)可以测量溶于水的氧分子的浓度变化。电极在三维步进电机控制下按照事先设定好的取样规则从一点到另一点地运行，可进行一维，二维，三维或者按照用户自设的复杂路径测量。不同种类的极化电极，如Clark whalen型、阴极型氧电极，碳纤维NO电极，还有很多其他种类的极谱电极都得到了广泛的应用。

SVET
SVET(扫描振荡电极技术)能够以最低每点约50毫秒的速度，在纳伏（nV）量级测量电压的梯度。正弦波发生器驱动压电晶体传感器以实现二维的振荡。电极振荡频率可达200Hz到1KHz，不会对电压梯度造成扰动。配有专门为SVET设计的PSD-2放大器。

SLEIS
PSD-2放大器和前置放大器同样适用于SLEIS（扫描局部电化学阻抗谱技术）在1KHz以下范围（比较经典的是30-100Hz范围）的测量。实际上，一种方法是将微电极固定不动，用PSD-2的振动器驱动样品，直接或通过电势恒定器。另一种模式是一个轴向使用SVET,另一个使用SLEIS,在电势恒定器的控制下同时对样品进行扫描。这种测量方式可以给使用者提供很高的敏感性，但是同时在空间分辨率上受电极尖端所限，一般直径5-50微米。

DVIT
DVIT（视频差成像技术）是一种定位金属表面腐蚀的图像辨别技术，可对一系列图像的微小差别进行计算和分析，从而鉴别出腐蚀开始的位置。有时需要在溶液中加入化学指示剂染料作为辅助。并可以和SVET或SIET联合使用，同时获得数据。

 Applicable Electronics was established in 1984. The corporate mission is to design, develop and market computer-controlled, rapid, non-invasive, scanning microelectrode measurement systems to detect ionic currents in conductive solutions. The major fields of application for these NDT techniques are biology and corrosion.

Applicable Electronics works together with Science Wares, Inc. Falmouth, MA to continue systems development. Applicable Electronics designs and manufactures system hardware. Eric Karplus, owner of Science Wares, Inc. is the owner and software engineer of the ASET (Automated Scanning Electrode Techniques) software package as well as the mechanical designer and manufacturer of some of the system components.

Both Alan Shipley and Eric Karplus were employed at the Marine Biological Laboratory in Woods Hole, MA at the National Vibrating Probe Facility (NVPF), which, since 1995, is called the Bio-Currents Research Center. The NIH Division of Research Resources in 1981 established the NVPF and continues funding under its new name, BRC. Shipley and Karplus worked together to build the NVPF by assisting Dr. Carl Scheffey and Dr. Lionel Jaffe in the development of the scanning microelectrode techniques. Since 1994, they are both full-time business professionals dedicated to the development and marketing of these techniques to the world.

Both companies work closely with the laboratory of Dr. Hugh Isaacs of Brookhaven National Laboratory, Upton, NY to continue systems development as they are applied to corrosion studies. Applicable Electronics was awarded a Phase I SBIR grant from the U.S. Department of Energy, September, 2001. Alan Shipley was PI and Brookhaven National Labs and Science Wares were contractors on the grant. Project title: "Non-Invasive Techniques to Study Local Passivity Breakdown of Metal Alloys in Aqueous Media". Phase II award, May 30, 2002. The project was a success and produced the DVIT (Differential Video Imaging Technique) which is now available for sale. This is a rapid NDT system for detecting initial corrosion. A patent is pending.

Applicable Electronics has donated the necessary equipment and expertise to help create the University of Massachusetts Vibrating Probe Facility, in Amherst, MA under the direction of Professor Joseph G. Kunkel. The purpose is to continue development of the equipment in a working laboratory for use in biological studies. Applicable Electronics also provides student fellowships at the facility. Science Wares, Inc. donates software, machining and technical support to this facility.
