Piezo 1 is a mechanosensitive channel which means, it can sense external mechanical forces such as fluid flow-induced shear stress,

osmotic stress, and pressure-induced membrane stretch [1]. Moreover, “studies have demonstrated wide expression of the Piezo1 channel that enables many different types of cells to sense a diversity of “outside-in” mechanical forces, including indentation, membrane stretch, shear stress, osmotic stress, ultrasound, and compression”. Since piezo 1 channel could also be activated by traction forces, there are two different mechanisms that have been proposed to explain the mechanical activation of piezo 1 channel. These mechanisms are called “force-from-lipids” and “force-from-filaments”. [https://www.frontiersin.org/articles/10.3389/fphar.2019.01304/full]

For the “force-from-lipids” mechanism, membrane tension is induced by mechanical forces. This membrane tension leads to a reorganization of lipids within and surrounding the channel proteins. This reorganization of lipids results into membrane lipid-channel protein interactions that induce the channel to open. We can note that a recent study (Lin et al., 2019) gave support to this mechanism.
