| Summary: | Wearable devices are making significant impact in changing the current healthcare industry.
These devices are capable of helping patients read their vital signs and provide warning
indication when critical condition was detected. Smart contact lens is growing popular such
that even big companies like google have come out with a conceptual lens. This is very
convenient for patients with chronic diseases such as diabetes as a smart contact lens can
provide non-intrusive methods by the usage of their glucose level. However, much research on
smart contact lens uses wireless communication for the transmission of data which requires the
use of an external receiver. Hence, electrochromic alarm system is an alternative mode of data
transmission, but it requires a power supply system. Existing studies have incorporated lithium
ion battery in smart contact lens. However, lithium ion battery is dangerous to be used on the
eye as it has a high voltage range.
In this project, power supply system with battery using ions in tear and self-charging by solar
energy harvesting, would be designed and implemented on the smart contact lens. This will
remove the requirement of an external transmitter or receiver used in wireless power supply. |
