The invention discloses a self-generating electric drill column vibration sensor with a deformable edge and a design method, and potential difference is generated by utilizing interaction among charges, so that an electric signal is generated to deduce a measurement parameter of drill column vibration. Compared with other traditional sensors, the sensor does not need to provide power and is more suitable for the underground environment; according to the drill string vibration sensor, the clay particles are combined with water to form a cement mixture, and the mixture can be filled in containers in any shape. Therefore, the vibration sensor can be arranged in a cement mixture and then cured in an underground high-temperature environment, on one hand, the sensor can be applied to drill collars and drill columns with any section shapes, on the other hand, the sensor can be fixed after the cement mixture is cured, and the reliability of the sensor is improved. 本发明公开了一种边缘可变形的自发电钻柱振动传感器及设计方法，利用电荷之间的相互作用产生电势差，从而产生电信
