Harvested energy unleashed
News & Analysis  
12/15/2008   Post a comment
For many, the concept of energy harvesting is tightly associated with the 'green' movement. While that's certainly one aspect, it overlooks a whole range of applications that have less to do with solving the world's so-called energy crisis and more to do with solving the problem of powering remote or embedded devices -- indefinitely. That is, without wires and without potentially expensive battery replacement, thereby truly cutting the wire.

Adapt standard tests to non-standard devices: Automotive qualification of a MEMS-based sensor system
Design How-To  
12/11/2008   Post a comment
AEC-Q100 does not address MEMS and unencapsulated devices. This is where the engineer designing the test plan must get creative in seeking a solid physics-of-failure-based test regime. The authors prove that an exposed humidity sensor can survive a lifetime of humidity-temperature and bias, tests particularly severe for the sensor and its exposed wire bonds.
