摘要： The present invention provides a flexible and stretchable wearable electronic device system. The system includes a sweat-activated battery that has an anode and a cathode and a dry electrolyte-impregnated carrier in contact with the anode and the cathode. A sweat-absorbing layer is in contact with the dry electrolyte-impregnated carrier. An adhesive layer is provided for attaching the sweat-activated battery to the skin of a user. A flexible electronic device such as a sweat sensor or a lighting element is connected to the sweat-activated battery and is powered by the sweat-activated battery.

摘要： An activation device for a battery for an electronic ignition mechanism has an ampoule filled with an electrolyte and a device for breaking the ampoule. The breaking device contains two leaf spring elements, which are fixed with a prestress on a component in the housing interior and between which the ampoule is clamped. At least the leaf spring element which supports the ampoule on the bottom side snaps from a first shape into a second shape when a force due to acceleration is applied.

摘要： A battery includes a battery casing defining a chamber therein, and an electrolyte powder disposed in the chamber. The electrolyte powder is configured to surround a zinc material that is separated from the electrolyte powder by a permeable separator sheet. The battery also includes a conductive member having a first end configured for electrical communication with an anode terminal of the battery, and, a second end configured for electrical communication with the zinc material. A conductive layer is also disposed between an inner surface of the casing and the electrolyte powder, the conductive layer being configured for electrical communication with a cathode terminal of the battery. There is also a liquid release mechanism configured for allowing release of a liquid in the chamber to activate an ion flow between the electrolyte powder and the zinc material via the permeable separator sheet.

摘要： Methods and systems for providing battery backup power to a home or other building are disclosed. Methods and systems include a fluid container holding an electrolyte solution. The electrolyte solution is prevented from flowing through an array of galvanic cells having annular flow paths via a fluid flow control mechanism, such as a valve, which is energized by an external power source. When the external power source is removed, such as during a power outage, the fluid flow control mechanism is deenergized and electrolyte solution is allowed to flow through the galvanic cell array, generating electric current. Energy produced by the system then powers the home or other building until the external power source returns, which in turn closes the fluid flow control mechanism and ceases energy production by the system.

摘要： A body-mountable device includes an electrochemical battery configured to provide power when exposed to an aqueous fluid. The aqueous fluid could be blood, sweat, tears, or some other bodily fluid. The electrochemical battery includes an anode that includes zinc metal and is configured to provide an electrical potential relative to a cathode when the anode and cathode are exposed to oxygen and an aqueous fluid. The electrochemical battery could provide power to electronics configured to measure a physiological parameter at a plurality of points in time, to record such measured parameters, to transmit such measured parameters to an external system, or to perform some other functions. Components of the body-mountable device could be embedded in a polymeric material configured for mounting to a surface of an eye. Components of the body-mountable device could be disposed on a flexible substrate configured for mounting to a skin surface.
