Voltree Power’s patented bioenergy harvester converts living plant metabolic energy to useable electricity, providing a unique battery replacement alternative. When coupled with our software and low-power transceiver hardware, this technology makes practical the deployment of large-scale, long-term sensor networks in a variety of previously inaccessible environments, such as under triple-canopy or in hostile terrain. Voltree Power’s bioenergy harvester can be used with temperature and humidity sensors as shown below, or with a wide variety of other sensors.

Benefits of this technology include:
- Enables the use of mesh sensor technology where it would otherwise be difficult to install power devices or hard-to-reach sensor devices for maintenance.
- Eliminates the cost of (hundreds) of thousands of batteries, labor costs associated with battery replacement/maintenance, along with environmental and labor costs of responsible battery disposition/recycling.
- Does not depend on wind, light, heat gradients, or mechanical movement.
- Weather-resistant and completely quiet.
- Absence of any heat or noise signatures, making it ideal for various covert, security-sensitive sensing applications.
- Environmentally benign to produce and operate.
- Parasitically harvests metabolic energy from any large plant without harming it.
- Useful lifetime of the device is only limited by the lifetime of the host.
Javelin Embedded
Javelin Embedded is a version of Voltree Power’s Javelin node that can be used with Voltree Power’s bioenergy harvester or with other renewable power sources. Like other Javelin nodes, Javelin Embedded allows for the collection and transmission of sensor data from remote or hard-to-reach areas.
