摘要：
Pulsed electromagnetic field (PEMF) apparatuses and methods of making and using them. In particular, described herein are two-part PEMF apparatuses that include a self-contained, lightweight, small, compact (e.g., in some variations, wearable) generator unit that is adapted to releasably and replaceably mate with an applicator unit. The generator unit typically includes a power source and a controller that generated PEMF waveforms to be applied, including the shape and timing of the PEMF waveforms. The applicator unit typically includes a radio frequency (RF) power amplifier, a loop antenna, and impedance matching circuitry for matching the impedances for the connection between the antenna loop and the RF power amplifier. Thus, the generator module may control the application of PEMF signals without requiring impedance matching between the separable generator unit and the applicator unit. The applicator unit can include a plurality of variable capacitors that can be used to tune the PEMF signals.
