• The proposed optical wake-up receiver drastically reduces the power consumption by more than one third compared to other wake-up receivers which could be a milestone in the medical field if successfully conducted. 1.INTRODUCTION Wireless sensor network is spatially distributed autonomous sensors deployed for monitoring the physical conditions and organizing the collected data at the central control unit [1]. According to previous research work, traditionally RF solutions exhibits high standby power which is more than 10pW. [...]the sensing accuracy of ultrasound wake-up receiver will be affected by soft or curved materials due to the difficulties in reading reflections from the material [8]. [...]it has 4.4pW standby power, which is still considered high compared to the previous research with 695pW standby power of optical wake-up receiver [9]. Otherwise, protocol controller will always in standby mode to reduce the power consumption. 3.RESULTS AND ANALYSIS 3.1.Design of an on-chip optical wake-up receiver The circuit functional blocks in the wake-up receiver as shown in Figure 4.
