Abstract:
1. An electronic sensing device, comprising: a blanket, on which a circuit unit is provided, having a plurality of blanket couplers; wherein the blanket has at least a plurality of connecting regions, where a plurality of sensor units are mounted thereto, and the plurality of blanket couplers include first blanket couplers and second blanket couplers for each of the plurality of connecting regions; wherein the circuit unit includes first wires and second wires, the first wires having ends that are attached to the first blanket couplers and the second wires having ends that are attached to the second couplers of each of the plurality of connecting regions, and the first and second wires being connected to a display unit; wherein a plurality of sensor units, which each have an impact surface, are detachably fastened to the blanket and electrically connected to the plurality of blanket couplers; wherein each of the plurality of the sensor units include an up conductive layer, a low conductive layer, at least a first sensor unit coupler, and at least a second sensor unit coupler, further wherein the up conductive layer is electrically connected to the first sensor unit coupler, which is electrically connected to the first blanket coupler, and the low conductive layer is electrically connected to the second sensor unit coupler, which is electrically connected to the second blanket coupler, and the up conductive layer is insulated from the low conductive layer in a normal condition, and the up conductive layer is warped to contact the low conductive layer when the impact surface receives an external force; wherein each of the plurality of sensor units further include an insulating layer between the up conductive layer and the low conductive layer which has at least an opening for the warped up conductive layer contacting the low conductive layer through the opening; wherein each of the plurality of sensor units further include a front sheet with the impact surface thereon and a rear sheet to sandwich the up conductive layer, the insulating layer, and the low conductive layer therebetween, and the up conductive layer is behind the front sheet; wherein a respective one of each of the first blanket couplers and the second blanket couplers are detachably engaged with the first sensor coupler and the second sensor coupler of each of the plurality of sensor units to fix each of the plurality of sensor units on one of the plurality of connecting regions of the blanket; and wherein the display unit is electrically connected to the circuit unit of the blanket to show a message when the impact surface of each of the plurality of sensor units receive an external force.
