Strategic Elements (SOR) has powered a Bluetooth sensor device using a moisture-powered battery.
The company equipped a computing device with both temperature and humidity sensors, plus onboard Bluetooth communication, and then harvested energy from moisture in the air. This was then converted to power a Cypress Semiconductor IoT sensor kit.
The Cypress Semiconductor IoT sensor kit is a development platform for devices with Bluetooth low energy (BLE) wireless connectivity. The kit demonstrates the potential of various components for a wide range of devices, like smart buildings and homes where temperature and humidity are core sensors.
Strategic Element’s graphene oxide-based battery ink technology allows extremely small, thin and light-weight battery cells to be printed onto surfaces like glass and flexible plastic.
The battery cells are designed to be powered and self-charged solely by humidity in the air or from the skin — an environmentally friendly source of energy, compared to alternatives based on lithium and coin cells.
Testing showed the company’s battery ink cells could enable real time temperature and humidity data to be captured and transmitted wirelessly to a laptop via sensors and a BLE communication module over the five-hour testing period, with a sampling rate of seven seconds.
This also marked the first time battery ink cells were integrated with a commercial supercapacitor. The company says this is a significant advancement, as higher performance applications require a supercapacitor or battery for greater energy storage.
The company says it is now looking into battery ink designed to produce a battery pack with a large number of miniature battery cells. By scaling down cell size, more batteries can be made in the same area, which could lead to increased power output.
Engineering to customise the battery ink for screen printing has already been conducted, and the company says it is aiming to finalise development and testing of a prototype battery ink formulated for screen printing over the next few weeks.
Additionally, the company says it’s looking to develop a prototype battery pack which can produce over a milliamp of electrical current by mid Q3 2021, which could dramatically expand the range of electronic devices the battery could power.
