A major OEM has a goal of developing a disposable consumer product incorporating a miniature battery. The device has to operate in contact with human tissues and fluids. The battery targets included to support device operation for a full day, fit in a miniature non-linear cavity and be completely bio-compatible with human tissues. The OEM had spent considerable time developing the device and searching for a power solution. After several attempts to find a battery partner able to develop such unique product, and failing to develop it in-house, this OEM eventually connected with FlexEl.
