An open‐loop self‐adaptive wireless power transfer system using magnetic resonance coupling for implantable biosensors, which provides stable wireless power regardless of variations in operating distance and lateral misalignment between the transmitting and receiving antennas, is proposed. According to adaptive impedance matching algorithms under the minimum reflected power conditions, the proposed system achieves an improved power transfer efficiency of maximum 47% within the operating distance. © 2016 Wiley Periodicals, Inc.
