There are many advantages to this new technology, however there are always negative impacts. This technology will most likely to be fairly expensive, and probably only the wealthier people of society will be able to afford it. This poses a problem because the countries in most need of this technology are poor countries, therefore the citizens will not be able to afford it. Being expensive this technology will not benefit the world, since most of the world cannot afford it.

When prosthetics are made, they cannot immediately go on the market. There is a very intense legal ramification that must occur first. Each part of the prosthetic must endure extensive testing in order to see if there are abnormalities or malfunctions. This process makes the prosthetic even more expensive on the market.

The time period where the arm is being developed can also be hazardous to the environment. The arm requires many materials to build including silicone. Silicone is a cancerous material and its disposal can prove dangerous. Also, while developing the arm, many tested arms that will be disposed. Although they will try to recycle the material from the arm, there will always be waste. These disposed parts can harm the environment. Even after the Piezo-sensory arm is developed, unused or outgrown artificial parts will be disposed by people, and can again be harmful to the environment.
The piezoelectric arm requires more integration with human tissue than other arms. There may be complications if the arm does not integrate well, and the body might reject the implants. Although the product would have gone through extensive testing, testing cannot always tell everything. If the arm does not integrate well with the body, there may be new consequences we never faced before.
