Mechanical structures for smart-phone enabled sensing
The paper presents a new strategy for sensor design that is made possible by the usage of ubiquitous mobile devices for signal capture, digitization, and data processing. The approach taken is to design simple mechanical sensor elements such that they produce a sensor output that is easily acquired...

The paper presents a new strategy for sensor design that is made possible by the usage of ubiquitous mobile devices for signal capture, digitization, and data processing.
