NFC Controlled Battery Free Smart Lock - Electronica 2022

At Electronica 2022, we stopped by the Infineon stand to see what they had on show. Among a huge range of solutions for pretty much every part of the industry, one thing, in particular, caught our eye.

A seemingly normal padlock opened with a phone. The catch? There are no batteries anywhere involved and minimal circuitry. An onboard capacitor stores charge from the NFC poller - in this case, a smartphone - and when a threshold is met, a low-power MCU brokers secure entry before triggering a solenoid, unlocking the padlock. All via energy harvested from NFC.
This was one of several examples of similar uses for the tech at the stand, including a mockup 3d model that lays bare how simple the circuitry is. We spoke with Stathis from Infineon about the NFC lock and how it slots into Infineon's solutions for smart home designs.
