Title

A 200 mm by 100 mm Smart Dust system with an average current consumption of 1.3 nA

Abstract
In this paper we present a microscale ""Smart Dust"" type system with a volume of 200 mm × 100 mm × 10 mm, called lablet. The lablet contains a 20 Hz low power clock generator, a sensor, electric actuators and a simple finite state machine to implement a predefined response to the sensor input. The system operates with supply voltages ranging from 0.3 V to 1.8 V and is thus suitable to be supplied from a capacitor with decreasing voltage. An input rectifier allows powering the lablet independent of polarity. The average current consumption of the system was measured to be 1.3 nA when supplied from a capacitor with an initial voltage of 1.8 V. The system is intended to be used within electrolyte solutions. The small system scale allows the investigation of ""pourable electronics"", a concept where large quantities of microsystems are deployed within a chemical solution to perform a predefined task. Several lablets have been designed and fabricated in a standard 180 nm CMOS process and the electrical functionality has been verified by contacting the lablet electrodes with multiple probe needles.
