Connecting Miniaturized Devices

Miniaturized devices also expand medical service beyond the hospital environment. Large machines have been reduced in size and provide a number of advantages and new applications. As more devices are used, countertop space, wall mounts, and systems and wireless controls in smaller offices. Also, with device capability expanding, the early, low-cost disposable tools are being replaced with smart devices that do more for the physician and are reusable. Higher-end medical devices are expanding the services available in the doctor’s office and reducing time to diagnosis. Emergency and portable medical equipment are being utilized in areas from airports and ambulances to group medical stations for sporting events.

Early technology examples of the new medical era include dental x-ray chips that eliminate the use of film, stethoscopes, esophageal scopes, and arthroscopic surgery tools. A number of catheter systems now include electronic chips placed temporarily below the epidermis or touching brain tissue to monitor symptoms, such as seizures. Bone conduction and subcutaneous electronics are routinely applied to children with extreme hearing loss.

To operate and use these electronic systems, nano and miniature connectors are fit into the designs, enabling increased portability, lower weight, and product sterilization (when necessary). Systems using nano connectors have pioneered the research of brain mapping, and fit into most cochlear implant hearing technologies. Probe tips, motor drives, and transesophageal probes all require the use of micro and nano connectors to support miniaturization or reuse of the where applicable. Often times, micro and nano connectors are molded into the medical device, module, or probe tip and become part of the whole instrument. Micro and nano connector reliability becomes key to the application as this industry grows and expands. To this end, the focus on high-reliability and long range performance are critical in the design of interconnects into the new era of “medical quality” micro and nano systems.

Xray M18: Love it! but... - R/C Tech Forums

1: Even though I got 31 tires in the trade, I can only make TWO SETS !... One foam (What I am using now), and one rubber, which need to be re-glued very badly. The rest are composed of pairs of matching tires, and a few sets missing one of the tires, and quite a few single odd-balls... Is there anywhere that I can get the tires for cheap? I looked real quick and the cheapest I could find was $14 shipped for a pair of 2. I really like the foams, they have good grip on all surfaces, but I feel like I am going to destroy them on concrete.
