Electron Beam Writer Enables Microfabrication

Integrated electronics could activate prosthetics. The new electron beam writer housed in the cleanroom facility at the Qualcomm Institute, previously the UCSD division of the California Institute of Telecommunications and Information Technology, is important for two major areas of research by Shadi Dayeh, PhD, an electrical and computer engineering professor. He is developing next-generation, nanoscale transistors for integrated electronics. At the same time, he is working to develop neural probes that can extract electrical signals from brain cells and transmit the information to a prosthetic device or computer. To achieve this level of signal extraction or manipulation requires tiny sensors spaced very closely together for the highest resolution and signal acquisition. Enter the new electron beam writer.

Heart Pump with Behind-the-Ear Power Connector

One-third of patients with heart pumps develop infection at abdominal connection. Cardiac surgeons and cardiologists at the University of Maryland Heart Center are part of a multi-center clinical trial evaluating the efficacy of powering heart pumps through a skull-based connector behind the ear. The pumps, called left ventricular assist devices (LVADs), support the heart’s main pumping chamber, the left ventricle. LVADs are implanted in the chest and powered with external batteries. Typically, these devices, which are used for patients with severe heart failure, are powered through an electrical cord connected at the abdomen, where potentially deadly infections can develop.

Robotic Exoskeleton Vastly Improves Quality of Life

Worldwide an estimated 185 million people use a wheelchair daily. A company based in Auckland, New Zealand, has developed an innovative robotic technology that helps people with mobility impairment get back on their feet— the Rex Bionics robotic exoskeleton. Its integrated maxon motors help to ensure smooth limb movement.

Electrical and Mechanical Integration in Aerospace Design

This paper addresses the issue of increasing complexity of today's aerospace electrical systems. Manufacturers now seek a high degree of integration between their business and design tools. MCAD, ECAD, PLM, PDM, Workflow and ERP systems are no longer selected purely through their individual functionalities, they must also integrate - and the integration must include all data in the process.

Key Considerations for Integrating Wireless Technology in Medical Devices

Significant opportunities exist to incorporate wireless technology into medical devices. Wireless technology increases the effectiveness of countless every day functions. While some simply are about the convenience factor, like being able to quickly transmit patient records from one hospital to another via email, others have the power to be lifesaving. Medical device manufacturers know that there is significant opportunity to incorporate wireless technology into medical devices. However, design engineers who are extremely knowledgeable about the design of medical devices face a number of challenges in marrying off-the-shelf wireless chipsets with proprietary medical devices in development.

Self-Charging Power Cell for Small Devices

A hybrid power cell uses a new technique for electrical charge conversion and storage. Scientists at Georgia Tech say that they have developed a new self-charging power cell technology that directly converts mechanical energy to chemical energy. Then, the power is stored until it is needed to generate electricity. This hybrid generator- storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries, they say.
