Introduction

The integration of Edge AI into implantable bioelectronics marks a paradigm shift in the way healthcare is delivered through medical devices [1]. Implantable devices, such as pacemakers, insulin pumps, and neurostimulators, have traditionally relied on cloud-based systems for data processing and decision-making [2]. However, these cloud-based systems introduce significant challenges in terms of latency, energy consumption, and data security [3]. The need for real-time, life-saving decisions in critical healthcare scenarios has revealed the limitations of relying solely on remote servers for data analysis. Cloud-based systems often experience delays in data transmission and processing, which can be detrimental when immediate intervention is required [4]. Edge AI overcomes these challenges by enabling the processing of physiological data directly on the device, allowing for near-instantaneous responses. By decentralizing data processing, Edge AI ensures faster, more efficient decision-making and enhances the overall performance of implantable bioelectronics [5].

In implantable bioelectronics, the need for low-latency decision-making is critical to ensure patient safety [6]. Medical devices must be capable of responding autonomously to changing physiological conditions, such as abnormal heart rhythms, fluctuating glucose levels, or neurological changes [7]. For instance, a pacemaker needs to detect arrhythmias in real time and adjust the pacing rate without delay, preventing the risk of cardiac arrest [8]. Similarly, an insulin pump must adjust insulin delivery promptly based on real-time glucose data to avoid dangerous spikes or drops in blood sugar. By processing data directly on the device, Edge AI allows for immediate decision-making, eliminating the delays associated with transmitting data to external servers [9]. This reduction in latency enhances the reliability of implantable devices, ensuring timely interventions in critical healthcare situations [10].

The power consumption of implantable devices is another significant challenge that Edge AI addresses effectively [11]. Implantable bioelectronics operate within stringent power limitations due to the small size of the batteries used in these devices [12]. Maintaining a long-lasting battery life is crucial since the devices are expected to function autonomously for extended periods, often years, without needing to be replaced or recharged [13]. Traditional cloud-based systems exacerbate this issue by requiring continuous wireless communication for data transmission, consuming a substantial amount of energy. In contrast, Edge AI allows devices to process data locally, reducing the need for frequent data transmission [14]. By minimizing data communication to external servers, Edge AI enables the device to conserve energy, extending the operational life of the battery. Moreover, Edge AI optimizes the computational efficiency of algorithms, ensuring that even resource-constrained devices can perform real-time data analysis and decision-making with minimal power consumption [15].
