□ Purpose & contents
The primary goal of our research is to develop a green smart patch and its software applications. The proposed smart patch will consume around 100uW of power, and it will be operating without battery using energy harvesting solution. Throughout our research works, the following techniques will be developed:
- Ultra low-power sensor interface circuit and analog-digital converter.
- Low complexity DSP techniques and ultra low-power implementations of DSP.
- A reconfigurable processor whose performance is comparable to ASIC in terms of performance/watt.
- Low-power integrated RF transceiver for wireless link.
- Green energy harvesting techniques to derive power from light and body heat.
- Smart path application software and clinical trials for the smart patch.

□ Result
Our proposed green smart patch, which is a wearable, battery-less and reliable medical device, will be clinically verified and used for patients' biomedical signal diagnosis and analysis. The contents of our research are as follows:
- Development of low-noise 5uW sensor interface circuit and 1uW analog-digital converter, which are required to sense the continuous analog signal generated from human body and to convert the sensed analog signal into digital.
- Digital sub-threshold circuit design techniques development for ultra-low-power design of DSP blocks.
- Design of reconfigurable functional units and hardwired control units (static control units) for minimizing the overhead due to programmable execution,
- Development of ultra-low-power and highly efficient energy harvesting circuit using light and body heat.
- Development of ultra-low-power unit block circuits as well as integrated RF transceiver, which are required to transmit the medical information acquired by the smart patch to external devices requires.
- Development of pulse oximetry, as one example of applications, and its application software in the 1st phase. Clinical trials on a number of intraoperative or asthma patients for validating the effectiveness of the smart patch. In the 2nd phase, development of a green smart patch supporting multiple clinical applications.

□ Expected Contribution
- The developed pulse oximetry patch and multi-purpose green smart patch are expected to enhance the mobility of the patients who need continuous check-up and enable the real time monitoring of the oxygenation of the patients' hemoglobin.
- The proposed HW/SW co-design methodology is expected to be used for the general applications as well as the patch owing to its low-power design capability.
- The developed ultra-low-power RF and analog circuit design techniques are expected to be applied to various battery-less implementation of wireless links.
- The proposed energy harvesting method is expected to be applied to various battery-less electronic systems that operate being attached to human skins.
