I am looking for information on some kind of actuator which can produce about 1 mm displacement while consuming low power, was thinking of piezoelectric ones as they can have "ms" response time. Any leads much appreciated.

Piezoelectric multilayer with flextensional amplification may solve your need. These actuators have displacement / stroke from few micron to mm range at lesser driving voltage. Blocked force vary accordingly. Response time from microsec to millisec is possible with such actuators.
Premkumar S. Thank you sir, could you forward any relevant publication ?

Amplified Piezoelectric actuators are commercially available. You can select based on your requirement.
Few publications with different configurations
1 Design, fabrication, and testing of flexurally amplified piezo actuator
2 High frequency, large displacement, and low power consumption piezoelectric translational actuator based on an oval loop shell
3 New “HAPA”, “FTA”, and “HD-FTA” Piezoelectric Actuators
Many publications are available that you can get it on search
