Abstract:
1. A microelectromechanical (MEMS) apparatus comprising: a MEMS transducer having plurality of exterior surfaces; and a compliant isolation mechanism surrounding the plurality of exterior surfaces; a housing substrate defining an aperture into which the MEMS transducer is at least partially disposed, and where the compliant isolation mechanism separates the MEMS transducer from the housing substrate wherein the compliant isolation mechanism comprises plural layers of elastomeric-strain-absorbing-material surrounding some of the plurality of exterior surfaces of the MEMS transducer; wherein the plural layers of elastomeric-strain-absorbing-material comprises a first ESAM layer at least partially disposed adjacent the MEMS transducer and a second ESAM layer at least partially disposed adjacent first ESAM layer, wherein the first ESAM layer has an elasticity modulus value lower than an elasticity modulus value of the second ESAM layer.
