Isolation, according to the data sheet, is 4kV. Aside from the hole for the current-under-test, the 19.9 x 19.4 x 8mm device only has three pins: oV, +Vcc and output, plus two sturdy solder-in lugs ...

The team built a prototype sensor with 260 pixels, each made from up to 5 sensor nanowires for each transistor nanowire. In tests, 80% of the sensor circuits worked as desired (see image, right).
