Abstract

A sensing device has at least two remote units mounted on an attachable tape, the remote units being mounted on separate branches of the attachable tape, a controller mounted on the attachable tape, electrical connections at least between each remote unit and the controller, the electrical connections on the attachable tape, and a surface to which the tape is attached such that the branches are separated from each other. A method of manufacturing a sensing device, including providing an attachable substrate, and fabricating electronic devices on the substrate, the electronic devices including at least two remote units, a controller and electrical connections between the remote units and the controller, and arranging the electronic devices such that at least two remote units are separated from each other.

Claims

1. A sensing device, comprising:

at least two remote sensing units mounted on an attachable tape, the remote sensing units being mounted on separate branches of the attachable tape, wherein the tape is an attachable, flexible substrate upon which the remote units and other electrical components reside, strips of which form the branches;

a controller mounted on the attachable tape such that each branch is defined by a regions of the tape between the controller and a remote sensing unit;

electrical connections at least between each remote sensing unit and the controller, the electrical connections on the attachable tape; and

a surface to which the tape is attached such that the branches are separated from each other.

2. The sensing device of claim 1, wherein the flexible substrate comprises one of paper, plastic, metal, or cloth.

3. The sensing device of claim 1, wherein at least one remote sensing unit comprises a sensor for sensing one of temperature, pressure, radiation, acceleration, acoustic information, magnetic field, moisture, gases, chemical or biological substances.

4. The sensing device of claim 1, wherein the controller includes at least one of a power supply, drive electronics, memory circuits or a user read out device.

5. The sensing device of claim 1, the branches being configured in a tetrahedron layout.

6. The sensing device of claim 1, wherein the electrical connections comprise multiple electrical connections and each sensing unit comprises multiple remote sensing units and only one of the electrical connections and one of the multiple sensing units in the branch is used.

7. The sensing device of claim 1, wherein each remote sensing unit is a different distance from the controller.

8. The sensing device of claim 1, wherein the remote sensing units are pressure sensors to detect blasts and the surface is a helmet.

9. The sensing device of claim 1, wherein at least one branch has an adjustable length portion between the remote unit and the controller.

10. The sensing device of claim 9, wherein the adjustable length portion comprises one of elastomeric portions of the substrate with associated stretchable conductive regions for electrical connection;

electrically conductive epoxies or polymers embedded with conductive particles;

meandering conductive traces;

carbon nanotubes or conductive nanowires embedded in an elastomeric material;

a bendable portion;

or stretchable fabric with woven conductive fibers.
