    • An electrochemical suspended element-based sensor system includes a solution cell for holding an electrolyte comprising solution including at least one electrochemically reducible or oxidizable species. A working electrode (WE), reference electrode (RE) and a counter electrode (CE) are disposed in the solution. The CE includes an asymmetric suspended element, wherein one side of the suspended element includes a metal or a highly doped semiconductor surface. The suspended element bends when current associated with reduction or oxidation of the electrochemically reducible or oxidizable species at the WE passes through the suspended element. At least one measurement system measures the bending of the suspended element or a parameter which is a function of the bending.
    • 基于电化学悬浮元件的传感器系统包括用于保持电解质的溶液池,所述电解质包含至少一种电化学还原性或可氧化物质的溶液。 在该溶液中设置工作电极(WE),参比电极(RE)和对电极(CE)。 CE包括不对称悬置元件,其中悬浮元件的一侧包括金属或高度掺杂的半导体表面。 当与WE的电化学还原性或可氧化物质的还原或氧化相关的电流通过悬浮元件时,悬浮元件弯曲。 至少一个测量系统测量悬挂元件的弯曲或作为弯曲函数的参数。
