  • Flexible, self-rolled superficial flow sensor
    Patent number: 10782164
    Abstract: A superficial flow sensor is provided, which may comprise a substrate, and a thin film comprising a self-rolled portion, a stationary portion, and a free ribbon portion. According to some aspects of the present disclosure, the self-rolled portion may be configured to have a residual stress and to deform under external forces.
    Type: Grant

  • FLEXIBLE, SELF-ROLLED SUPERFICIAL FLOW SENSOR
    Publication number: 20180356264
    Abstract: A superficial flow sensor may include a substrate; a thin film with a self-rolled portion, a stationary portion, and a free ribbon portion; an embedded strain gauge circuit; and at least one contact pad. According to some aspects, the self-rolled portion may deform under external forces, and the embedded strain gauge circuit may detect the deformation of the self-rolled portion.

  • Gaseous flow sensor and related method thereof
    Patent number: 9746361
    Abstract: A gas flow sensing device, and related method of manufacturing, comprising a conductive layer encapsulated in dielectric film, suspended over a cavity to form a diaphragm. The conductive layer functions as both a heating a sensing element and is patterned to provide uniform heat distribution across the diaphragm. The device is designed to sense flow from any direction relative to the device and the design of the dielectric film and diaphragm reduces sensor drift during prolonged operation.
