On the issue of cost, MEMS fabrication methods are always that high (and even higher) at inception, but will fall fast based on the huge volume potential. I can easily envision this at $1 in the very near future. But I see a possible drawback in the intended application. Reed switches are by nature, 'vicinity' switches. They are activated when magnetic field comes close to them. Once swallowed, it is going to get 'out-of-vicinity' of a passing magnet. I suppose if the design-intent is to swallow a switch (within whatever host device) and then undergo a powerful MRI, I could see the switch activating. But a more conventional handheld magnetic actuator, such as a pace-maker programmer for example, would have to output a substantially higher magnetic field than is presently achieved to activate the switch, assuming its resident within the bowels of the digestive tract. That's pretty deep.
Yes, a2, I think that the applications mentioned here are appropriate due to necessity. They are definitely high-end, and most applications don't call for a reed switch that costs several dollars. As the price goes down, though, the number of applications will rise.
Very true elizebath I also do agree with you on this. It's worth paying a premium price if the product is really a good rather than taking a risk with a low price, specially when it comes to an health care product.
True Elizebeth its seems to be that the company is practicing marketskiming pricing at the introductory level.
Anyway, when it comes to medical devices its still in the affordable level by the individuals.
Right now, an ingestible enoscope is big -- a pill measuring 25 mm long and 10 mm in diameter. I'd have to be pretty sick to agree to swallow a pill that large. That's why, as TJ points out, there will be applications for this technology before the cost comes down.
The Medical Device industry is an odd market place. The volume for products is not really that high, and if you have a unique device you can pretty much charge what ever you want, and company's do (sorry patients).
One of the strangest aspects to the industry is the reuse of disposable devices, like tubing sets. It's not that big of an issue in large, industrial nations, but in smaller countries tubing sets for various procedures are sometimes reused. Devices now try to track the tubing sets to make certain that they are not used more than once. As the tubing sets become more expensive, because of the electronics to prevent reuse, you then start to see bootleg tubing sets of dubious quality. Certainly worse than getting a bootleg Carolina Herrara bag.
@Elizabath: Indeed there are certain things which should consider as high priority than the cost. Health industry is one example for it. Quality plays a major role in these areas / industries and it should be focused in a much higher manner. So in such scenarios cost factor becomes secondary.
That's a good thing, Chuck, even though both you and TJ point out that sometimes the cost is worth it. I know personally I will pay a little extra for something because I do believe you get what you pay for. Health is one place where skimping wouldn't be such a great option.
The question of whether engineers could have foreseen the shortcut maintenance procedures that led to the crash of American Airlines Flight 191 in 1979 will probably linger for as long as there is an engineering profession.
More than 35 years later, the post-mortem on one of the country’s worst engineering disasters appears to be simple. A contractor asked for a change in an original design. The change was approved by engineers, later resulting in a mammoth structural collapse that killed 114 people and injured 216 more.
If you’re an embedded systems engineer whose analog capabilities are getting a little bit rusty, then you’ll want to take note of an upcoming Design News Continuing Education Center class, “Analog Design for the Digital World,” running Monday, Nov. 17 through Friday, Nov. 21.
