Ultra-Low-Power Capacitive Sensors (Sensors Europe 2020)

Dr Phil Poole, Director Semiconductors
Microdul AG

Presentation Summary

Microdul has developed some of the lowest power capacitive sensors. The presentation will first describe capacitive sensors based on a technique that automatically compensates slow changes to the background capacitance level and react to fast touch and proximity events. A new ultra-low-power (720nA) capacitive sensor based on a different principle will be described that can be used as a standalone capacitive switch or as a sensor that can output a capacitance value. This sensor can be used for a wake-up function for wearables, tags and cards. Further development of the ULP sensor for an EU-Horizon 2020 project called AMANDA will be illustrated.
