Introduction

Wei Yan is an inventor associated with Singapore and the Massachusetts Institute of Technology. His patent work concerns an acoustic fabric designed to detect sound through fibers integrated into a textile matrix.

Latest Patents

The provided information lists 1 patent for Wei Yan: “Highly Sensitive Acoustic Fabric Including an Acoustic Fiber Transducer.” The invention describes a fiber transducer with a piezoelectric domain made from non-centrosymmetric crystalline-phase piezoelectric material and inorganic piezoelectric particles. Electrically connected charge-collector domains gather charge generated in the piezoelectric domain, while conductors carry that charge to the end of the fiber as a signal indicating acoustic pressure on the textile matrix. An outer acoustic-energy transmission material is designed to match the matrix’s vibrational modes. The patent specifies a Young’s modulus of 0.3 Pa to 500 MPa for this material and a ratio of the relevant moduli between about 5 and about 70,000.
