The design and implementation of a novel piezoelectric-based actuator for an implantable middle-ear hearing aid is described in this paper. The proposed actuator has excellent low-frequency output characteristics. and can generate high output in a specific frequency band by adjusting the mechanical resonance. The actuator consists of a piezoelectric element. https://safeersappliancers.shop/product-category/hide-oven-with-variosteam-stainless-steel-60cm/
