Abstract
A downhole power generator module having a body with one or more couplings that are configured to connect the body to a downhole tool string positioned downhole in a wellbore. An axial passageway is formed through the outer housing and couplings. The power generator module has a pressure-driven electric generator such as a triboelectric or piezoelectric generator positioned within the body. A port in the body enables communication of well fluids from the wellbore to the generator. Pressure changes in the well fluids are communicated to the pressure-driven electric generator, causing it to autonomously generate electric power downhole. The generated power is provided directly to other downhole tools without intervention from the surface.
