break.data: Sample recording of SICM pipette breakage

In breakage: SICM pipette tip geometry estimation

Description

Position and current data recorded using a scanning ion conductance microscope in hopping mode. An elevated fall rate drove the pipette to overshoot its detection range and collide with the cover slip surface and break, altering its resistance.

Usage

data(break.data)

Format

A data frame with 9999 observations on the following 3 variables.

s

The time of each data point, in milliseconds from the start of the recording.

pA

The ion current passing through the pipette, in picoamps.

Z

The pipette position, in microns, recorded within the frame of reference of the SICM piezo actuator.
