Electrical stimulation has proven to be a promising therapeutic option in the treatment of various diseases and health conditions. In this context, adapting stimulation parameters and monitoring sensory data is an essential tool to investigate the underlying principles of electrical stimulation in preclinical studies. Current electrostimulating devices for studies in small rodents are wired or use radio frequency (RF) to communicate with the outside world. However, cables are a common source of infection and RF-capable devices are limited to large intra-PCB coils and low efficiency communication. We propose a highly miniaturized and energy-efficient RF module as an extension to electrically stimulating devices. The RF module is exemplarily presented in combination with a neurostimulation device featuring a compact and biocompatible encapsulation scheme for fully implantation in small rodents.
