Market Overview

This novel, self-powered sensor technology enables wireless transmission over a range of tens of meters without a motor or active power supply. The smart sensor market is expected to grow from 18.58 billion USD in 2015 to 57.77 billion USD by 2022, with the wireless sensor market share expected to reach over $940 million by 2020. However, all commercially available wireless sensors in the market require a power source. Clemson University researchers have developed a portable, self-powered wireless sensor that can be adapted to many applications such as smart electrochromic screens, security alarms, temperature and pressure sensors, and infrared sensors.


Electrochromic touch screens, security alarms, temperature and pressure sensors

Technical Summary:

This wireless sensor and transmitter is comprised of a tactile driven electric generator, using 3D-printed nanocarbon and polymer electrodes. The technology relies on two electrodes capable of producing > 2000 V, which when connected to a metal conductor is sufficient to create an electric field that can be used to wirelessly communicate a signal over range of few tens of meters. The sensor is completely self-contained and requires no additional power. Additionally, waveforms generated by the sensor can be modulated by mechanical action such as hand tapping in a given sequence. These waveforms are preserved in the wireless signal (akin to Morse coding) and can be detected by existing compatible commercial electronic receivers. Thus, the technology can be developed into products suitable for security applications requiring wireless transmission of codes.


  • Operates without batteries or an external power source, making it environmentally friendly, maintenance free, and long lasting
  • Comprised of simple design features and inexpensive materials, minimizing manufacturing costs
