About Wisepower

WISEPOWER srl is aimed at the design and prototyping of a new class of energy generators for mobile devices.

This idea originates from the discovery, made in the university laboratory, of a new technology that significantly improves the performances of a wide class of electric power generators. Based on this new technology and on the long-standing experience of the inventors in research activities, they decided to give birth to a company aimed at applying this technology to designing micro energy generators for mobile devices.

Mobile electronic devices are energy hungry and the standard existing solutions, i.e. batteries, present a number of back draws like large size and heavy weight, finite life-time, high costs.

WISEPOWER srl has developed a new approach to solve the energy needs of mobile electronic devices: extraction of energy from the ambient when and where is needed. Specifically, WISEPOWER srl has developed a new and innovative technology for the energy-conversion, based on the use of non-linear dynamics applied to physical systems. Vibrational, light, heat energies, to name a few, are harvested from the ambient and converted into the electric energy available for powering electronic devices.

A special class of devices where our generators can constitute a unique solution is the so-called wireless-sensor-networks (WSN). These are small size (form 10-6 to 10-12 m3) devices aimed at sensing physical signals (light, sound, temperature, humidity, chemical composition, …) and transmitting the collected information through short range radio connections. Each device is a node of a communication network. The information is passed from node to node until it reached a computer hub. Applications for WSN range from human health monitoring, to environment control, both for civil and military purposes.

These energy generators are designed to integrate and, in some cases, to substitute the standard batteries presently used for powering mobile electronic devices.

The standard batteries have a number of drawbacks. The main are:

1. Size: batteries are large and heavy. No micro-batteries are available on the market.
2. Duration: batteries have a finite life-time, need frequent re-charging and their performances decrease with time.
3. Environment: batteries are not environment-friendly. They need to be collected after use.
4. Cost: energy provided by batteries is derived from other energy sources. The production-storage-transport-use chain adds to the costs.
5. Safety: batteries are not explosion proof. If batteries are heated above a certain temperature can show disruptive behaviours.

Our energy generators have a number of advantages. The main are:

1. Size: our generators can be scaled down to micro dimensions. The principle of operation is robust and scale-independent up to few microns (10-6 m).
2. Duration: our generators are subject to charge-discharge hysteretic cycle, thus no relevant aging effect has to be expected. In principle such generators can be operated for years without maintenance or replacement.
3. Environment: our generators are environment-friendly for two main reasons: 1) they harvest energy from the ambient and do not use fossil energy produced elsewhere. 2) they are not made with highly polluting materials and can thus be dispersed in the environment without major problems.
4. Cost: our generators produce ready to use energy when and where is needed. No production-storage-transport-use chain costs are effective.
5. Safety: our generators are explosion-proof. They can be heated without any significant risk but malfunctioning.

As we pointed out, our generators can be integrated with existing (rechargeable) batteries in order to store the energy when the device does not use it and to increase the peak power needed by some devices.

Among the different ambient energy sources, the mostly common used are:

1. Photovoltaic: light is converted directly into electric power;
2. Heat: difference in temperature can be used to convert heat into electric energy;
3. Motion: kinetic energy of moving masses can be converted into electric energy.
