abstract = "Conductive hearing loss (CHL) is the most common type of hearing impairment among infants and young children. Most conductive hearing aids, including bone-anchored aids, are invasive and require surgical procedures to be implanted into the skull. In addition, non-invasive wearable conductive hearing aids are bulky, rigid, and unstable. Neither aid is ideal for infants and pediatric patients with conductive hearing loss. Here, we implemented a unimorph piezoelectric actuator into a flexible substrate to achieve a micro-epidermal actuator for non-invasive Band-Aid-like conductive hearing aids. The flexible aid will generate vibrations on the surface of skin and transmit to the cochlea through a skin-bone path, thus bypassing obstructions and damage in the auditory canal. We used finite element analysis to study vibrations from microepidermal actuators and obtain output force level. A Laser Doppler vibrometer was also used to measure displacement of vibrations for an actuator placed on a segment of a cadaveric skull calvarium.",
