An implantable device includes a body part and a piezoelectric part. The body part is configured to grasp a pulsatile organic or inorganic tissue. The piezoelectric part is mechanically coupled to the body part and is configured to convert a varying shear force transferred from the body part to the piezoelectric part into voltage. An implantable system, comprises the implantable device and a stent like object configured to be inserted and deployed within a pulsatile or static tissue. The implantable device is configured to form a sealed junction with the pulsatile tissue while pressing against an outer circumference area of the stent.
