    摘要： An electromechanical polymer (EMP) transducer may include (a) one or more EMP layers each having a first operating characteristic; and (b) one or more EMP layers each having a second operating characteristic different from the first operating characteristic. The EMP transducer may include at least two EMP layers that are activated independently, and one or more EMP layers being configured to be a sensing layer. The sensing layer may sensitive to one or both of the operating characteristics (e.g., temperature, strain, pressure and their respective rates of change). Other operating characteristic may include resin type, modulus, film thicknesses, degrees of deformations, operating temperature ranges, a stretching ratio of the EMP layers, metallization patterns of electrodes, arrangements of active and inactive EMP layers, arrangements of irradiated EMP layers, arrangements of EMP layers acting as sensors, and arrangements of inactive layers of various degrees of stiffness.

    摘要： In some embodiments, a sensor system may include a deformable structure and a sensing element. The deformable structure may include at least one layer of piezoelectric material and at least one actuator port disposed on the at least one layer of piezoelectric material. The deformable structure may deform in response to external phenomenon. The at least one actuator port may be configured to actuate the at least one layer of piezoelectric material via application of an electrical signal to the at least one layer of piezoelectric material. The at least one layer of piezoelectric material may be configured to apply a force to the deformable structure when actuated. The sensing element may be configured to sense deformation of the deformable structure capacitively, optically, or via a sensing port according to embodiments.

    摘要： A multi-axis transducer is provided. The transducer includes: a stationary member; at least two connecting members and two or more energy-conversion elements disposed on each connecting member. Each connecting member is attached at one location thereof to one of the stationary member or a second connecting member and, in response to a stimuli, is free to move along any of three geometric axes that are perpendicular to each other. Each energy-conversion element operates to convert motion of the connecting member to electrical energy or vice versa. A common geometric plane passes through each of the at least two connecting members and the stationary member, and the two largest dimensions of each connecting member defines a geometric plane that is parallel with the common geometric plane.
