Abstract:
An apparatus for characterizing a first material property of a first array of samples and a second material property of a second array of samples, comprising:a) a first array of 5 or more sensors wherein each sensor of said first array of 5 or more sensors is configured to be associated with at least one sample of said first array of samples; b) a second array of 5 or more sensors interchangeable with said first array of 5 or more sensors wherein each sensor in said second array of 5 or more sensors is configured to be associated with at least one sample of said second array of samples; c) electronic test circuitry interchangeably in electrical communication with said first array of 5 or more sensors and said second array of 5 or more sensors through at least one electrical interconnection device wherein said electronic test circuitry is configured for sending an output signal to said first array of samples and said second array of samples respectively through said first array of 5 or more sensors and said second array of 5 or more sensors and said electronic test circuitry is further configured for receiving input signals from said first array of samples and said second array of samples, wherein; i) said first material property of said first array of samples is determined by comparing said output signals sent to said first array of 5 or more sensors with said input signals from said first array of samples; and ii) said second material property of said second array of samples is determined by comparing said output signals sent to said second array of 5 or more sensors with said input signals from said second array of samples.
