Here, we report a bioinspired electrostatic\u2010field sensor that implements a solid\u2010state analogue of electrolocation using a corona\u2010polarized fluoropolymer electret. The pre\u2010charged electret establishes a quasi\u2010static electric field, and nearby objects reshape this field to induce measurable potential modulation on a grounded electrode, enabling friction\u2010free sensing without active emission or mechanical contact. The sensor detects both conductive and dielectric targets (metals, polymers, glass), while waveform features encode material\u2010dependent electrical signatures. The device achieves a near\u2010field change in separation sensitivity of 1.05\u00a0V per 50\u00a0\u00b5m and maintains stable responses over 10,000 approach\u2010withdraw cycles. Combined with machine\u2010learning models, the platform enables proximity warning, touch\u2010free interaction, material discrimination, coating\u2010defect recognition, gesture decoding, and gesture\u2010to\u2010robot control. This work establishes electrostatic\u2010field perturbation as a robust strategy for low\u2010power, multifunctional noncontact
