With the rapid development of flexible interconnection technology in active distribution networks (ADNs), many power electronic devices have been employed to improve system operational performance. As a novel fully-controlled power electronic device, energy storage integrated soft open point (ESOP) is gradually replacing traditional switches.
After charging and then turning off the external input voltage, the energy storage module can effectively sustain the release of ionic drugs. The drug release stops when the external wireless charging is closed and all the electrical energy stored in the supercapacitors is exhausted.

In particular, the energy storage module is fully made of biodegradable materials while achieving high electrochemical performance (including a high capacitance of 93.5 mF cm −2 and a high output voltage of 1.3 V), and its charge storage mechanism is further revealed by comprehensive characterizations.
However, advances in power modules have lagged far behind the tissue-integrated sensor nodes and circuit units. Here, we report a soft implantable power system that monolithically integrates wireless energy transmission and storage modules.
In this study, a phase-changing soft open point (PC-SOP) is proposed as a new way of connecting soft open points (SOPs) to balance the power flows among three phases by controlling active power and reactive power. Then an operational strategy based on PC-SOPs is presented for three-phase four-wire unbalanced systems.
