re: Panel casts doubt on MEMS for energy harvest

I do not want to look polemic, but I am not convinced by Mr. Andosca's argument regarding cloth dryers. I agree that this development could save power and money and I wish every dryer could feature those sensors. But on a practicle point of view, I do not see how a consumer would accept to pay a premium on a dryer for something which is not necessarily of huge interest. And I do not see why a dryer manufacturer would decide to include a new, non-mature device in its machine without a demand from the market. Appart from a governmental decision making mandatory such devices in dryers, I do not think there will ever be a market pull for this technology. This is typical techno-push. This kind of reasoning applies to a lot of examples regarding energy harvesting!

@AntoineB I agree it looks like technology push. But I might buy a clothes dryer that would switch itself off when the drum had reached a certain, selectable humidity....rather than dialing up a time.

Dryers already monitor the clothes and switch off when they are dry. I just looked on Sears.com and the cheapest dryer I found has this feature: Auto Dry monitors air temperature with an automatic thermostat and ends the cycle when clothes are properly dried

The clothes dryer costs of the order of $300 - $600. Why would a "premium" of $5 be a problem? Such consumer IoT devices will have to be sold for the sort of money that many people pay daily for a latte, and there is no reason why that price point cannot be achieved. Unlike the 5 cent RFID tag, there is still a real business in products which cost a few dollars each (with volumes eventually in the hundreds or millions or more).

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
