  • Publication number: 20110215931
    Abstract: Sensing a force and/or a change of motion proximate to a person's head via one or more sensing elements (e.g., a pressure sensor, an accelerometer) disposed on a flexible substrate having a sufficient mechanical coupling to the person's head. The conformality of the sensing element facilitates intimate proximity to the surface of the person's head to ensure accurate sensing. A processor receiving one or more signals from the sensing element may provide information relating to possible injury to a body part (e.g., head trauma) resulting from sensed forces and/or changes in motion. Such information may be conveyed by one or more output devices that provide indications of possible degrees of injury/trauma. A conformal sensing apparatus may be integrated with a protective garment or accessory, such as a helmet, wherein the conformality of the sensing apparatus also ensures sufficient comfort for the wearer.

  • Publication number: 20110034912
    Abstract: System, devices and methods are presented that integrate stretchable or flexible circuitry, including arrays of active devices for enhanced sensing, diagnostic, and therapeutic capabilities. The invention enables conformal sensing contact with tissues of interest, such as the inner wall of a lumen, a the brain, or the surface of the heart. Such direct, conformal contact increases accuracy of measurement and delivery of therapy. Further, the invention enables the incorporation of both sensing and therapeutic devices on the same substrate allowing for faster treatment of diseased tissue and fewer devices to perform the same procedure.

  • Publication number: 20100116526
    Abstract: In embodiments, the present invention may attach at least two isolated electronic components to an elastomeric substrate, and arrange an electrical interconnection between the components in a boustrophedonic pattern interconnecting the two isolated electronic components with the electrical interconnection. The elastomeric substrate may then be stretched such that the components separate relative to one another, where the electrical interconnection maintains substantially identical electrical performance characteristics during stretching, and where the stretching may extend the separation distance between the electrical components to many times that of the unstretched distance.

  • Publication number: 20100087782
    Abstract: A system, device and method are presented for utilizing stretchable active integrated circuits with inflatable bodies. The invention allows for such operative features to come into direct contact with body structures, such as the inner wall of a lumen. Such direct contact increases accuracy of measurement and delivery of therapy.

  • Publication number: 20100073016
    Abstract: One aspect of the invention relates to an ultrathin micro-electromechanical chemical sensing device which uses swelling or straining of a reactive organic material for sensing. In certain embodiments, the device comprises a contact on-off switch chemical sensor. For example, the device can comprises a small gap separating two electrodes, wherein the gap can be closed as a result of the swelling or stressing of an organic polymer coating on one or both sides of the gap. In certain embodiments, the swelling or stressing is due to the organic polymer reacting with a target analyte.

  • Patent number: 7644489
    Abstract: A passive nanomagnet alignment method is described to self-align a membrane to another surface. The membrane and the surface each have a plurality of nanomagnets patterned on it, wherein the nanomagnets are magnetized based on an applied external magnetic field. The membrane is brought into close proximity and coarse alignment to the surface by a positioning mechanism (e.g., an actuation force), such that the nanomagnets on the membrane attract to and self-align with the nanomagnets on said surface based on the nanomagnet magnetizations.
