| Just Add Parts and Shake . . .
| | | This column usually focuses on prosaic and proven applications for circuits and sensors. This month, though, I am going to talk about an emerging field called evolvable hardware, which potentially has tremendous applicability to designing robust sensing and control systems. |
| | Zzzzappp!
| | | When someone with a static charge buildup touches an electronic device the damages to the IC are not difficult to detect. It's the secondary ESD effects that are hard to troubleshoot because they might not hit the IC. |
| | MEMS Technology's True Potential
| | | Two recent market studies quantify the market for MEMS technology very differently. Both studies predict strong growth, but neither seems to touch on what I view as the true potential for microelectromechanical systems (MEMS) and micro-systems technology (MST). |

| The ΔΣ ADC Learns New Tricks
| | | A new architecture is blurring the distinction between successive approximation register (SAR) and ΔΣ ADCs, creating devices that couple high resolution with high throughput, achieving exceptional measurement accuracy and ease of integration. |
| | Optimizing Analog Front-Ends for Data Acquisition
| | | A general-purpose data acquisition (DA) system has to deal with input signals ranging from millivolts to tens of volts, wide frequency ranges, and a great variety of sensor types. Getting the most out of your analog front-end involves choosing your ADC and amplifier carefully. |

| Expand Your Gaming Space with Sensors
| | | Proximity sensors and accelerometers are changing the gaming experience as we know it today. While these technologies are not new, improvements in user acceptance, size, performance, and price are spurring their use in the gaming market. |
| | Is That Meat Okay to Eat?
| | | There's yet another food spoilage detector that can detect high levels of bacterial activity in poultry and other meats destined for the table. SensorfreshQ sniffs out biogenic amines that can be picked up by a handheld device that passes an air sample over the item of interest. |
| | And Check the Silverware Too
| | | At Cornell University, researchers are working on a new table napkin made of nanofibers that can advise of the presence of microorganisms you don't want to ingest. |

| |  | A Machine That Watches
| | | During an automated manufacturing process, the product typically moves along a production line at either constant or variable speeds. The first task of optoelectronic inspection is to discard that motion. For example, machine vision systems use triggers and shutters and photoelectric sensors use gates to freeze the object at a particular point in time so that it can be analyzed. |
