TZ SMArt Devices
Making the ordinary extraordinary
Unlike conventional electronic locks, TZ SMArt Devices use advanced Shape Memory Alloy (SMA) materials as actuators and embedded sensors to optimize operation. This technology offers a number of strong advantages including allowing for innovative physical designs and packaging.
TZ SMArt Devices are based on one of three current actuation topologies:
- Rotary actuation: this is where the SMA is configured to rotate the mechanism in a radial fashion, opening a series of pawls or similar mechanisms to release a capture pin or stud
- Flex actuation: this is the case where the SMA is used to bend or flex the mechanism so that the lock can release a spring loaded latch or clear an interference device so that the lock can operate
- Linear actuation: is where the SMA is used in a linear fashion to pull a shuttle or clear an interference mechanism away from an engagement point in the lock
