Sensors that monitor infrastructure, such as bridges or buildings, or are used in medical devices, such as prostheses for the deaf, require a constant supply of power. The energy for this usually ...

In Part I of this series, we explored the differences between user interfaces based on mechanical buttons and those utilizing capacitive touch sensors. In Step 1 we discussed the look and feel of a ...

Designing a sensing application involves circuitry for amplification of a sensor signal, its conditioning and, in most cases, conversion into digital form. This is achieved conventionally by using ...
