We study pyroelectric and electromechanical effects in the prototype antiferroelectric liquid crystal 4-(1-methylheptyloxycarbonyl-phenyl)4'-octylbiphenil-4-carboxylate (MHPOBC). The linear electromechanical effect in the freely suspended liquid crystal films of MHPOBC has been detected in the broad temperature range inclusive of the antiferroelectric SmCA* as well as paralelectric SmA. The anomalous behavior of the hysteresis loop of SmCβ* in the (pyroelectric coefficient, dc bias electric voltage) coordinates has been found.
