Miniaturized hexapod MEMS microrobots with two kinds of actuators were described in this paper. The actuator of MEMS microrobots had two types which were shape memory alloy (SMA) actuator and piezoelectric (PZT) actuator. For PZT type microrobot, a piezoelectric element was affixed outside the rotor. The piezoelectric element would be expanded by electrical pulses and impacted on the rotor to generate...
The popular electrostatic discharge (ESD) protection device, multi-finger NMOS with gate-coupling technique for better uniform turning-on, can be affected by process variation. The transmission line pulsing (TLP) test results reveal this phenomenon. The trigger voltage of the same pin on some products shifts from 9.5 V to 15.5 V. No such significant difference was ever reported in the literature....
