Ellefsen et al. monitor Piezo-dependent Calcium signals in live cells by TIRF and super-resolution microscopy and find that Ca2+ flickers localize to areas of high traction force. They show that Myosin II activity and MLCK are needed for the generation of Piezo Ca2+ signals and that Piezo1 channels are mobile in the plasma membrane.
