Abstract: Described herein are manufacturing techniques for achieving stress isolation in microelectromechanical systems (MEMS) devices that involve isolation trenches formed from the backside of the substrate. The techniques described herein involve etching a trench in the bottom side of the substrate subsequent to forming a MEMS platform, and processing the MEMS platform to form a MEMS device on the top side of the substrate subsequent to etching the trench.

Abstract: A microfluidic ion detector for detecting heavy metal ions in liquid and particulate matter from gas samples is described. The microfluidic ion detector includes a sample extraction structure for extracting sample ions from a sample liquid or extracting sample ions from the particulate matter of a gas sample, a separation structure for separating sample ions of different types once extracted, and a detection structure for detecting the sample ions. The microfluidic ion detector also includes a reference reservoir providing a reference ion against which the sample may be calibrated based on the operation of the separation structure. A portable, self-calibrating ion detector may be realized by including the described components on a single substrate.
