A minimally invasive blood‐extraction system is fabricated by the integration of an elastic self‐recovery actuator and an ultrahigh‐aspect‐ratio microneedle. The simple elastic self‐recovery actuator converts finger force to elastic energy to provide power for blood extraction and transport without requiring an external source of power. This device has potential utility in the biomedical field within the framework of complete micro‐electromechanical systems.
