The main problem with this so far has been the small power that could be generated with these harvesting circuits.
Some researchers have now presented a new approach that might make this more feasible in the future. It is based on piezoelectric zinc-oxide nanowires aound 2-3 um in diameter.
Due to their small dimensions these nanowires promise a power generation per volume significantly higher than achieved with current techniques.

They claim the "Sonic Slide 3000" is the worlds thinnest fingerprint sensor with superb accuracy and low power requirements.
The sensor is based on a piezoceramic array with an imaging zone of 9.6mmx0.4mm creating a 256 shade geryscale image of the finger.
The applicaiton maybe questionable, with more and more fingerprint-based applications all around us, but the technology is rally interesting as there could be lots of other applications for it.

Yole has recently published a preliminary overview of the top 30 MEMS manufacturers for 2008.
One of their main conclusions is that the financial crisis effects each MEMS device and hence each manufacturer differently. The more mature and closer related to the automotive sector a MEMS device is the bigger the impact.
Even though, Bosch seems to have done pretty well moving up to 4th place.

Many of the clusters have a kind of "one-stop-shop" approach to attract more customers.

an online portal that will serve as a matchmaker for companies in the entire MEMS supply chain, from material suppliers to OEMs.
This certainly sounds interesting as it could make life for people in the MEMS and related businesses much easier to identify suppliers, potential collaborators etc.
At the moment the directory however is rather US-centric with only a couple of non-US companies in the directory and it only lists companies which are members of the MIG.
This will likely put potential users of the portal off as in fact it does not cover the entire MEMS supply chain, but only a small part of it, namely only companies willing to pay to be included in this directory.
In conclusion: Great idea, but opening the portal to non-MIG member-companies would in my opinion greatly benefit the directory.
It uses a thin silicon cantilever with integrated trackes used to both heat the cantilever and measure it's heating profile.
As the temperature profile depends on the nature of the materials condensed onto the cantilevers and is significantly different for explosives and non-explosives, it can be used to identify explosives.
