摘要

描述了一种新型微型（28毫米× 38毫米）屏蔽法拉第杯，用于量化毫米环境物体上的皮库仑电荷，如小昆虫或植物，液滴，灰尘颗粒或粉末。静电计电子元件包含在设备内，避免任何低电平信号传输到外部静电计。它使用电压斜坡-电容方法进行校准，在没有参考静电计的情况下产生定义的电荷脉冲。该装置可以安装在声学悬浮器中，为小物体提供无接触、零泄漏的悬浮，测量它们释放时的电荷。方便和简单的使用打开了新的环境收费测量机会。

A Faraday cup for charge measurements in biophysical and environmental fieldwork

A novel miniature (28 mm × 38 mm) shielded Faraday cup is described for quantifying picocoulomb charges on millimetre environmental objects, such as small insects or plants, droplets, dust particles or powders. The electrometer electronics is contained within the device, avoiding any transfer of low level signals to an external electrometer. It is calibrated using a voltage ramp – capacitor method, generating defined charge pulses without a reference electrometer. The device can fit within an acoustic levitator to provide non-contact, zero leakage suspension of small objects, measuring charge on their release. Convenience and simplicity of use open new environmental charge measurement opportunities.
