A Story of Energy Parasite – for Presentation

by Peiqi Su on April 16, 2013

Please go to my blog to see the latest update. Say “Hello World” I’m an energy parasite on your finger! Where it comes from? The ancestor The ancestor of our energy parasite is a bio mechanical energy harvester from a paper: Biomechanical Energy Harvesting: Generating Electricity During Walking with Minimal User Effort. [First draft] Literature Reviews .|| […] more…

Hello world! This is my energy parasite, in prehistoric times. I’m sure it’s future generations could be better. Materials The small signal diode solved the problem that the current generated by piezo element is too little to be forwarded. The max forward voltage is 1V when the current is 10 mA [Datasheet]. The 3mm LED works better than the […] more…

Finger Parasite – Product Development

by Peiqi Su on April 4, 2013

  The idea is to make a “parasite” on a finger. The “parasite”, as a ring, could opportunistically harvest small bit of energy form the movement of a finger. After a series of tests, the Piezo Element turned out to be a feasible material. Test 1: Piezo Vibration Sensor (Large) In my test, this Piezo Vibration Sensor could generate up […] more…

“Breath Parasite” is an idea that to harvest energy from every breath. For the minimum viable product, I tried to 1) transfer the linear motion to rotation (motion) ; 2) rotate a DC motor to generate electricity which could power a LED (power). 1. Motion: linear motion –> rotation (photo) 2. Power: electromagnetic induction Parts: […] more…

“Finger Parasite” is an idea that to harvest energy from finger motion, mainly for using mouse and typing. For the minimum viable product, I tried to attach a flex sensor to and finger and use Precessing to generally measure the quantity of finger movement. 1. The expriments Parts: 22k ohm resistor*1, SpectraSymbol flex sensor*1   […] more…

Harvest Small Energy from Human Motion

by Peiqi Su on March 10, 2013

My concept is to opportunistically harvest small bit of energy from human motion. (will pick up one motion to project) From a higher level, to build a system which harvest body energy, monitor body conditions and visualize the data on/around body.

Fitbit data charts

by Peiqi Su on March 4, 2013

I tried FitBit One for days, from Feb.19 to Feb 21. It recorded my daily steps, walking distance, burning calories, time in bed times of awakenings and so on. Here is the line chart of my daily waking steps and distances:   My daily waking steps and burning calories: what is my average stride length? […] more…

Generating Electricity During “Using The Mouse”

by Peiqi Su on February 26, 2013

My interests in biomechanical energy sprouted in childhood. In many cartoons, I always saw a bulb lit up on top of someone’s head when this character came up with an idea. At that time, I believed that something must change inside our body when we are thinking. A few years later, a program on Discovery showed […] more…

Science + Design => Holistic Product UX

by Peiqi Su on February 19, 2013

It was a great lecture that Dr. Dan Formosa shared his experience in applying biomechanics to product design. I’m very interested in the product: “Cimzia Home Injection Experience” and read the related paper: The effect of a new syringe design on the ability of rheumatoid arthritis patients to inject a biological medication (http://www.sciencedirect.com/science/article/pii/S000368701100072X) (NYU access only). The paper […] more…
