Wearable devices for diagnosing health conditions or monitoring the surrounding environment are being increasingly developed. Continuous monitoring using wearable devices requires suitable sensors, data processing systems, and wireless communication systems. Although these components are widely available, they are often rigid and bulky, hindering their application to wearable devices. Moreover, dedicated systems should be developed with specific circuitry and sensors because data acquisition and processing require different systems and algorithms depending on the device type and purpose. In this study, devices and assembly‐type concepts toward miniaturized flexible devices are analyzed to acquire and process biosignals and environmental measurements. The concepts are applied to a wireless communication system for transmitting data obtained from a sensor. The resulting modular devices provide high compatibility and enable various functions and physical configurations. The operation of a wireless communication system is verified using a pulse oximeter, a UV sensor, a gyroscope, and a temperature sensor that provide quantitative information after postprocessing using a microcontroller. The experimental results suggest the system applicability in various fields such as healthcare and the Internet of Things, especially suited for wearable device solutions.
