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.

Ultra-Sensitive Biosensor for Medical Diagnostics

This device may enable miniaturization and new point-of-care applications in doctors' offices. Researchers have created an ultrasensitive biosensor that could open up new opportunities for early detection of cancer and “personalized medicine” tailored to the specific biochemistry of individual patients. The device, which could be several hundred times more sensitive than other biosensors, combines the attributes of two distinctly different types of sensors, said Muhammad A. Alam, a Purdue Uni versity professor of electrical and computer engineering.

Coaxial Nanocable Could Aid in Energy Storage

Researchers at Rice University have created a coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors. The nanocable was produced with techniques pioneered in the burgeoning graphene research field and could be used to build next-generation energy-storage systems.

Functional Electrical Stimulation Technique May Improve Neural Implants

Researchers improve the efficiency of devices that stimulate damaged nerves, reducing potential side effects. Electrical implants that shut down excessive activity in brain cells hold great potential for treating epilepsy and chronic pain. Likewise, devices that enhance neurons’ activity may help restore function to people with nerve damage.

Fully Printed Carbon Nanotube Transistor Circuits for Displays

Organic light-emitting diode (OLED)-based displays are used in cell phones, digital cameras, and other portable devices. But developing a lower-cost method for mass-producing such displays has been complicated by the difficulties of incorporating thin-film transistors that use amorphous silicon and polysilicon into the production process.
